Definitions
- Hospitals, nursing homes, and other patient care facilities typically include patient monitoring devices at one or more bedsides in the facility.
- Patient monitoring devices generally include sensors, processing equipment, and displays for obtaining and analyzing a medical patient's physiological parameters such as blood oxygen saturation level, respiratory rate, and the like.
- Clinicians including doctors, nurses, and other medical personnel, use the physiological parameters obtained from patient monitors to diagnose illnesses and to prescribe treatments. Clinicians also use the physiological parameters to monitor patients during various clinical situations to determine whether to increase the level of medical care given to patients.
- Blood pressure is one example of a physiological parameter that can be monitored.
- Many devices allow blood pressure to be measured by sphygmomanometer systems that utilize an inflatable cuff applied to a person's arm. The cuff is inflated to a pressure level high enough to occlude a major artery. When air is slowly released from the cuff, blood pressure can be estimated by detecting “Korotkoff” sounds using a stethoscope or other detection means placed over the artery.
- a device for obtaining physiological information of a medical patient can include a blood pressure device that can be coupled to a medical patient and a wireless transceiver electrically coupled with the blood pressure device.
- the wireless transceiver can wirelessly transmit blood pressure data received by the blood pressure device and physiological data received from one or more physiological sensors coupled to the blood pressure device.
- a single cable is also provided for connecting multiple different types of sensors together.

- the blood pressure device 110 includes a wireless transceiver 116 , which can transmit sensor data obtained from the patient 101 to a wireless transreceiver 120 .
- the patient 101 is advantageously not physically coupled to a bedside monitor in the depicted embodiment and can therefore have greater freedom of movement.
- the blood pressure device 110 a includes an inflatable cuff 112 , which can be an oscilometric cuff that is actuated electronically (e.g., via intelligent cuff inflation and/or based on a time interval) to obtain blood pressure information.
- the cuff 112 is coupled to a wireless transceiver 116 .
- the blood pressure device 110 a is also coupled to a fingertip optical sensor 102 via a cable 107 .
- the optical sensor 102 can include one or more emitters and detectors for obtaining physiological information indicative of one or more blood parameters of the patient 101 .
- the optical sensor 102 can also be used to obtain a photoplethysmograph, a measure of plethysmograph variability, a measure of blood perfusion, and the like.
- the blood pressure device 110 a is coupled to an acoustic sensor 104 a via a cable 105 .
- the cable 105 connecting the acoustic sensor 104 a to the blood pressure device 110 includes two portions, namely a cable 105 a and a cable 105 b .
- the cable 105 a connects the acoustic sensor 104 a to an anchor 104 b , which is coupled to the blood pressure device 110 a via the cable 105 b .
- the anchor 104 b can be adhered to the patient's skin to reduce noise due to accidental tugging of the acoustic sensor 104 a.
- the acoustic sensor 104 a can be a piezoelectric sensor or the like that obtains physiological information reflective of one or more respiratory parameters of the patient 101 . These parameters can include, for example, respiratory rate, inspiratory time, expiratory time, inspiration-to-expiration ratio, inspiratory flow, expiratory flow, tidal volume, minute volume, apnea duration, breath sounds, rales, rhonchi, stridor, and changes in breath sounds such as decreased volume or change in airflow.

- the velocity of the exciter waveform can be calculated by a processor (such as a processor in the wireless transceiver 120 , described below). From this velocity, the processor can derive a blood pressure measurement or blood pressure estimate.
- the processor can output the blood pressure measurement for display.
- the processor can also use the blood pressure measurement to determine whether to trigger the blood pressure cuff 112 .
- the acoustic sensor 104 placed on the upper chest can be advantageously combined with an ECG electrode (such as in structure 208 of FIG. 2B ), thereby providing dual benefit of two signals generated from a single mechanical assembly.
- the timing relationship from fidicial markers from the ECG signal, related cardiac acoustic signal and the resulting peripheral pulse from the finger pulse oximeters produces a transit time that correlates to the cardiovascular performance such as blood pressure, vascular tone, vascular volume and cardiac mechanical function.
- Pulse wave transit time or PWTT in currently available systems depends on ECG as the sole reference point, but such systems may not be able to isolate the transit time variables associated to cardiac functions, such as the pre-ejection period (PEP).
- the addition of the cardiac acoustical signal allows isolation of the cardiac functions and provides additional cardiac performance metrics. Timing calculations can be performed by the processor in the wireless transceiver 120 or a in distributed processor found in an on-body structure (e.g., such as any of the devices herein or below: 112 , 210 , 230 , 402 , 806 ).

- Movement and/or position data can also be used as a contributing factor to adjusting parameter measurements. Blood pressure, for instance, can change during patient motion due to changes in blood flow. If the patient is detected to be moving, the patient's calculated blood pressure (or other parameter) can therefore be adjusted differently than when the patient is detected to be sitting.
- a database can be assembled that includes movement and parameter data (raw or measured parameters) for one or more patients over time.

Description
- This application claims priority benefit under 35 U.S.C. §120 to and is a continuation-in-part of U.S. patent application Ser. No. 12/840,209, filed Jul. 20, 2010, entitled “Wireless Patient Monitoring System,” which claims the benefit of priority under 35 U.S.C. §119(e) of the following U.S. Provisional Patent Applications:

App. No. Filing Date Title Attorney Docket 61/226,996 Jul. 20, 2009 Wireless Blood MASIMO.730PR Pressure Monitoring System 61/259,037 Nov. 6, 2009 Wireless Blood MASIMO.730PR2 Pressure Monitoring System 61/290,436 Dec. 28, 2009 Acoustic MASIMO.763PR2 Respiratory Monitor 61/350,673 Jun. 2, 2010 Opticoustic Sensor MASIMO-P120 - Each of the foregoing applications is incorporated by reference in their entirety.
- Hospitals, nursing homes, and other patient care facilities typically include patient monitoring devices at one or more bedsides in the facility. Patient monitoring devices generally include sensors, processing equipment, and displays for obtaining and analyzing a medical patient's physiological parameters such as blood oxygen saturation level, respiratory rate, and the like. Clinicians, including doctors, nurses, and other medical personnel, use the physiological parameters obtained from patient monitors to diagnose illnesses and to prescribe treatments. Clinicians also use the physiological parameters to monitor patients during various clinical situations to determine whether to increase the level of medical care given to patients.
- Blood pressure is one example of a physiological parameter that can be monitored. Many devices allow blood pressure to be measured by sphygmomanometer systems that utilize an inflatable cuff applied to a person's arm. The cuff is inflated to a pressure level high enough to occlude a major artery. When air is slowly released from the cuff, blood pressure can be estimated by detecting “Korotkoff” sounds using a stethoscope or other detection means placed over the artery.
- In certain embodiments, a device for obtaining physiological information of a medical patient can include a blood pressure device that can be coupled to a medical patient and a wireless transceiver electrically coupled with the blood pressure device. The wireless transceiver can wirelessly transmit blood pressure data received by the blood pressure device and physiological data received from one or more physiological sensors coupled to the blood pressure device. To further increase patient mobility, in some embodiments, a single cable is also provided for connecting multiple different types of sensors together.
- For purposes of summarizing the disclosure, certain aspects, advantages and novel features of the inventions have been described herein. It is to be understood that not necessarily all such advantages can be achieved in accordance with any particular embodiment of the inventions disclosed herein. Thus, the inventions disclosed herein can be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as can be taught or suggested herein.
- Various embodiments will be described hereinafter with reference to the accompanying drawings. These embodiments are illustrated and described by example only, and are not intended to limit the scope of the disclosure. In the drawings, similar elements have similar reference numerals.

FIG. 7 illustrates an embodiment of a physiological parameter display that can be used with any of the patient monitoring systems described above. -
FIG. 8 illustrates a further embodiment of a patient monitoring system. - In clinical settings, medical sensors are often attached to patients to monitor physiological parameters of the patients. Some examples of medical sensors include blood oxygen sensors, blood pressure sensors, and acoustic respiratory sensors. Typically, each sensor attached to a patient is connected to a bedside monitoring device with a cable. The more cables that couple the patient to the bedside monitoring device, the more the patient's freedom of movement can be restricted. In addition, cables pose a tripping hazard to health care workers and make it difficult to perform rapid transport to therapeutic areas such as the operating room when emergency situations arise.
- This disclosure describes embodiments of wireless patient monitoring systems that include a wireless device coupled to a patient and to one or more sensors. In one embodiment, the wireless device transmits sensor data obtained from the sensors to a patient monitor. By transmitting the sensor data wirelessly, these patient monitoring systems can advantageously replace some or all cables that connect patients to bedside monitoring devices. To further increase patient mobility and comfort, in some embodiments, a single cable connection system is also provided for connecting multiple different types of sensors together.
- These patient monitoring systems are primarily described in the context of an example blood pressure cuff that includes a wireless transceiver. The blood pressure cuff and/or wireless transceiver can also be coupled to additional sensors, such as optical sensors, acoustic sensors, and/or electrocardiograph sensors. The wireless transceiver can transmit blood pressure data and sensor data from the other sensors to a wireless receiver, which can be a patient monitor. These and other features described herein can be applied to a variety of sensor configurations, including configurations that do not include a blood pressure cuff.
-
FIGS. 1A and 1B illustrate embodiments of wirelesspatient monitoring systems patient 101. The blood pressure device 110 includes awireless transceiver 116, which can transmit sensor data obtained from thepatient 101 to awireless transreceiver 120. Thus, thepatient 101 is advantageously not physically coupled to a bedside monitor in the depicted embodiment and can therefore have greater freedom of movement. - Referring to
FIG. 1A , theblood pressure device 110 a includes aninflatable cuff 112, which can be an oscilometric cuff that is actuated electronically (e.g., via intelligent cuff inflation and/or based on a time interval) to obtain blood pressure information. Thecuff 112 is coupled to awireless transceiver 116. Theblood pressure device 110 a is also coupled to a fingertipoptical sensor 102 via acable 107. Theoptical sensor 102 can include one or more emitters and detectors for obtaining physiological information indicative of one or more blood parameters of thepatient 101. These parameters can include various blood analytes such as oxygen, carbon monoxide, methemoglobin, total hemoglobin, glucose, proteins, glucose, lipids, a percentage thereof (e.g., concentration or saturation), and the like. Theoptical sensor 102 can also be used to obtain a photoplethysmograph, a measure of plethysmograph variability, a measure of blood perfusion, and the like. - Additionally, the
blood pressure device 110 a is coupled to anacoustic sensor 104 a via a cable 105. The cable 105 connecting theacoustic sensor 104 a to the blood pressure device 110 includes two portions, namely acable 105 a and acable 105 b. Thecable 105 a connects theacoustic sensor 104 a to ananchor 104 b, which is coupled to theblood pressure device 110 a via thecable 105 b. Theanchor 104 b can be adhered to the patient's skin to reduce noise due to accidental tugging of theacoustic sensor 104 a. - The
acoustic sensor 104 a can be a piezoelectric sensor or the like that obtains physiological information reflective of one or more respiratory parameters of thepatient 101. These parameters can include, for example, respiratory rate, inspiratory time, expiratory time, inspiration-to-expiration ratio, inspiratory flow, expiratory flow, tidal volume, minute volume, apnea duration, breath sounds, rales, rhonchi, stridor, and changes in breath sounds such as decreased volume or change in airflow. In addition, in some cases therespiratory sensor 104 a, or another lead of therespiratory sensor 104 a (not shown), can measure other physiological sounds such as heart rate (e.g., to help with probe-off detection), heart sounds (e.g., S1, S2, S3, S4, and murmurs), and changes in heart sounds such as normal to murmur or split heart sounds indicating fluid overload. In some implementations, a second acoustic respiratory sensor can be provided over the patient's 101 chest for additional heart sound detection. In one embodiment, the acoustic sensor 104 can include any of the features described in U.S. Patent Application No. 61/141,584, filed Dec. 30, 2008, titled “Acoustic Sensor Assembly,” the disclosure of which is hereby incorporated by reference in its entirety. - The acoustic sensor 104 can also be used to generate an exciter waveform that can be detected by the
optical sensor 102 at the fingertip, by an optical sensor attached to an ear of the patient (seeFIGS. 2A , 3), by an ECG sensor (seeFIG. 2C ), or by another acoustic sensor (not shown). The velocity of the exciter waveform can be calculated by a processor (such as a processor in thewireless transceiver 120, described below). From this velocity, the processor can derive a blood pressure measurement or blood pressure estimate. The processor can output the blood pressure measurement for display. The processor can also use the blood pressure measurement to determine whether to trigger theblood pressure cuff 112. - In another embodiment, the acoustic sensor 104 placed on the upper chest can be advantageously combined with an ECG electrode (such as in
structure 208 ofFIG. 2B ), thereby providing dual benefit of two signals generated from a single mechanical assembly. The timing relationship from fidicial markers from the ECG signal, related cardiac acoustic signal and the resulting peripheral pulse from the finger pulse oximeters produces a transit time that correlates to the cardiovascular performance such as blood pressure, vascular tone, vascular volume and cardiac mechanical function. Pulse wave transit time or PWTT in currently available systems depends on ECG as the sole reference point, but such systems may not be able to isolate the transit time variables associated to cardiac functions, such as the pre-ejection period (PEP). In certain embodiments, the addition of the cardiac acoustical signal allows isolation of the cardiac functions and provides additional cardiac performance metrics. Timing calculations can be performed by the processor in thewireless transceiver 120 or a in distributed processor found in an on-body structure (e.g., such as any of the devices herein or below: 112, 210, 230, 402, 806). - In certain embodiments, the wireless patient monitoring system 100 uses some or all of the velocity-based blood pressure measurement techniques described in U.S. Pat. No. 5,590,649, filed Apr. 15, 1994, titled “Apparatus and Method for Measuring an Induced Perturbation to Determine Blood Pressure,” or in U.S. Pat. No. 5,785,659, filed Jan. 17, 1996, titled “Automatically Activated Blood Pressure Measurement Device,” the disclosures of which are hereby incorporated by reference in their entirety. An example display related to such blood pressure calculations is described below with respect to
FIG. 7 . - The
wireless transceiver 116 can transmit data using any of a variety of wireless technologies, such as Wi-Fi (802.11x), Bluetooth (802.15.2), Zigbee (802.15.4), cellular telephony, infrared, RFID, satellite transmission, proprietary protocols, combinations of the same, and the like. Thewireless transceiver 116 can perform solely telemetry functions, such as measuring and reporting information about thepatient 101. Alternatively, thewireless transceiver 116 can be a transceiver that also receives data and/or instructions, as will be described in further detail below. - The
wireless receiver 120 receives information from and/or sends information to the wireless transceiver via an antenna (not shown). In certain embodiments, thewireless receiver 120 is a patient monitor. As such, thewireless receiver 120 can include one or more processors that process sensor signals received from thewireless transceiver 116 corresponding to the sensors 102 a, 102 b, 104, and/or 106 in order to derive any of the physiological parameters described above. Thewireless transceiver 120 can also display any of these parameters, including trends, waveforms, related alarms, and the like. Thewireless receiver 120 can further include a computer-readable storage medium, such as a physical storage device, for storing the physiological data. Thewireless transceiver 120 can also include a network interface for communicating the physiological data to one or more hosts over a network, such as to a nurse's station computer in a hospital network. - Moreover, in certain embodiments, the
wireless transceiver 116 can send raw data for processing to a central nurse's station computer, to a clinician device, and/or to a bedside device (e.g., the receiver 116). Thewireless transceiver 116 can also send raw data to a central nurse's station computer, clinician device, and/or to a bedside device for calculation, which retransmits calculated measurements back to the blood pressure device 110 (or to the bedside device). Thewireless transceiver 116 can also calculate measurements from the raw data and send the measurements to a central nurse's station computer, to a pager or other clinician device, or to a bedside device (e.g., the receiver 116). Many other configurations of data transmission are possible. - In addition to deriving any of the parameters mentioned above from the data obtained from the sensors 102 a, 102 b, 104, and/or 106, the
wireless transceiver 120 can also determine various measures of data confidence, such as the data confidence indicators described in U.S. Pat. No. 7,024,233 entitled “Pulse oximetry data confidence indicator,” the disclosure of which is hereby incorporated by reference in its entirety. Thewireless transceiver 120 can also determine a perfusion index, such as the perfusion index described in U.S. Pat. No. 7,292,883 entitled “Physiological assessment system,” the disclosure of which is hereby incorporated by reference in its entirety. Moreover, thewireless transceiver 120 can determine a plethysmograph variability index (PVI), such as the PVI described in U.S. Publication No. 2008/0188760 entitled “Plethysmograph variability processor,” the disclosure of which is hereby incorporated by reference in its entirety. - In addition, the
wireless transceiver 120 can send data and instructions to thewireless transceiver 116 in some embodiments. For instance, thewireless transceiver 120 can intelligently determine when to inflate thecuff 112 and can send inflation signals to thetransceiver 116. Similarly, thewireless transceiver 120 can remotely control any other sensors that can be attached to thetransceiver 116 or thecuff 112. Thetransceiver 120 can send software or firmware updates to thetransceiver 116. Moreover, the transceiver 120 (or the transceiver 116) can adjust the amount of signal data transmitted by thetransceiver 116 based at least in part on the acuity of the patient, using, for example, any of the techniques described in U.S. Patent Publication No. 2009/0119330, filed Jan. 7, 2009, titled “Systems and Methods for Storing, Analyzing, and Retrieving Medical Data,” the disclosure of which is hereby incorporated by reference in its entirety. - In alternative embodiments, the
wireless transceiver 116 can perform some or all of the patient monitor functions described above, instead of or in addition to the monitoring functions described above with respect to thewireless transceiver 120. In some cases, thewireless transceiver 116 might also include a display that outputs data reflecting any of the parameters described above (see, e.g.,FIG. 5 ). Thus, thewireless transceiver 116 can either send raw signal data to be processed by thewireless transceiver 120, can send processed signal data to be displayed and/or passed on by thewireless transceiver 120, or can perform some combination of the above. Moreover, in some implementations, thewireless transceiver 116 can perform at least some front-end processing of the data, such as bandpass filtering, analog-to-digital conversion, and/or signal conditioning, prior to sending the data to thetransceiver 120. An alternative embodiment may include at least some front end processing embedded in any of the sensors described herein (such assensors FIG. 8 ). - In certain embodiments, the
cuff 112 is a reusable, disposable, or resposable device. Similarly, any of thesensors cables 105, 107 can be disposable or resposable. Resposable devices can include devices that are partially disposable and partially reusable. Thus, for example, theacoustic sensor 104 a can include reusable electronics but a disposable contact surface (such as an adhesive) where thesensor 104 a comes into contact with the patient's skin. Generally, any of the sensors, cuffs, and cables described herein can be reusable, disposable, or resposable. - The
cuff 112 can also can have its own power (e.g., via batteries) either as extra power or as a sole source of power for thetransceiver 116. The batteries can be disposable or reusable. In some embodiments, thecuff 112 can include one or more photovoltaic solar cells or other power sources. Likewise, batteries, solar sources, or other power sources can be provided for either of thesensors - Referring to
FIG. 1B , another embodiment of thesystem 100B is shown. In thesystem 100B, theblood pressure device 110 b can communicate wirelessly with theacoustic sensor 104 a and with theoptical sensor 102. For instance, wireless transceivers (not shown) can be provided in one or both of thesensors blood pressure device 110 b. Theblood pressure device 110 b can transmit these signals on to thewireless transceiver 120. In addition, in some embodiments, theblood pressure device 110 b can also process the signals received from thesensors wireless transceiver 120. Thesensors wireless transceiver 120 or patient monitor. In one embodiment, thesystem 100B shown can be considered to be a body LAN, piconet, or other individual network. -
FIGS. 2A and 2B illustrate additional embodiments ofpatient monitoring systems FIG. 2A illustrates a wirelesspatient monitoring system 200A, whileFIG. 2B illustrates a standalonepatient monitoring system 200B. - Referring specifically to
FIG. 2A , ablood pressure device 210 a is connected to apatient 201. Theblood pressure device 210 a includes awireless transceiver 216 a, which can transmit sensor data obtained from thepatient 201 to a wireless receiver at 220 viaantenna 218. In the depicted embodiment, theblood pressure device 210 a includes aninflatable cuff 212 a, which can include any of the features of thecuff 112 described above. Additionally, thecuff 212 a includes apocket 214, which holds thewireless transceiver 216 a (shown by dashed lines). Thewireless transceiver 216 a can be electrically connected to thecuff 212 a via a connector (see, e.g.,FIG. 5 ) in some embodiments. As will be described elsewhere herein, the form of attachment of thewireless transceiver 216 a to thecuff 212 a is not restricted to a pocket connection mechanism and can vary in other implementations. - The
wireless transceiver 216 a is also coupled to various sensors inFIG. 2A , including anacoustic sensor 204 a and anoptical ear sensor 202 a. Theacoustic sensor 204 a can have any of the features of the acoustic sensor 104 described above. Theear clip sensor 202 a can be an optical sensor that obtains physiological information regarding one or more blood parameters of thepatient 201. These parameters can include any of the blood-related parameters described above with respect to theoptical sensor 102. In one embodiment, theear clip sensor 202 a is an LNOP TC-I ear reusable sensor available from Masimo® Corporation of Irvine, Calif. In other embodiments, theear clip sensor 202 a is a concha ear sensor (seeFIGS. 4A and 4B ). - Advantageously, in the depicted embodiment, the
sensors wireless transceiver 216 a via a single cable 205. The cable 205 is shown having two sections, acable 205 a and acable 205 b. For example, thewireless transceiver 216 a is coupled to anacoustic sensor 204 a via thecable 205 b. In turn, theacoustic sensor 204 a is coupled to theoptical ear sensor 202 a via thecable 205 a. Advantageously, because thesensors 202 a, 204 are attached to the wireless transceiver 216 in the cuff 212 in the depicted embodiment, the cable 205 is relatively short and can thereby increase the patient's 201 freedom of movement. Moreover, because a single cable 205 is used to connect bothsensors - In some embodiments, the cable 205 is a shared cable 205 that is shared by the
optical ear sensor 202 a and theacoustic sensor 204 a. The shared cable 205 can share power and ground lines for each of thesensors sensors sensors different sensors - The two
cables separate cables cable acoustic sensor 204 a via a single connector. As separate cables, in one embodiment, thecable 205 b can be connected to a first port on theacoustic sensor 204 a and thecable 205 a can be coupled to a second port on theacoustic sensor 204 a. -
FIG. 2B further illustrates an embodiment of the cable 205 in the context of a standalonepatient monitoring system 200B. In the standalonepatient monitoring system 200B, ablood pressure device 210 b is provided that includes apatient monitor 216 b disposed on acuff 212 b. The patient monitor 216 b includes adisplay 219 for outputting physiological parameter measurements, trends, waveforms, patient data, and optionally other data for presentation to a clinician. Thedisplay 219 can be an LCD display, for example, with a touch screen or the like. The patient monitor 216 b can act as a standalone device, not needing to communicate with other devices to process and measure physiological parameters. In some embodiments, the patient monitor 216 b can also include any of the wireless functionality described above. - The patient monitor 216 b can be integrated into the
cuff 212 b or can be detachable from thecuff 212 b. In one embodiment, the patient monitor 216 b can be a readily available mobile computing device with a patient monitoring software application. For example, the patient monitor 216 b can be a smart phone, personal digital assistant (PDA), or other wireless device. The patient monitoring software application on the device can perform any of a variety of functions, such as calculating physiological parameters, displaying physiological data, documenting physiological data, and/or wirelessly transmitting physiological data (including measurements or uncalculated raw sensor data) via email, text message (e.g., SMS or MMS), or some other communication medium. Moreover, any of the wireless transceivers or patient monitors described herein can be substituted with such a mobile computing device. - In the depicted embodiment, the patient monitor 216 b is connected to three different types of sensors. An
optical sensor 202 b, coupled to a patient's 201 finger, is connected to the patient monitor 216 b via acable 207. In addition, anacoustic sensor 204 b and an electrocardiograph (ECG)sensor 206 are attached to the patient monitor 206 b via the cable 205. Theoptical sensor 202 b can perform any of the optical sensor functions described above. Likewise, theacoustic sensor 204 b can perform any of the acoustic sensor functions described above. TheECG sensor 206 can be used to monitor electrical activity of the patient's 201 heart. - Advantageously, in the depicted embodiment, the
ECG sensor 206 is a bundle sensor that includes one or more ECG leads 208 in a single package. For example, theECG sensor 206 can include one, two, or three or more leads. One or more of theleads 208 can be an active lead or leads, while another lead 208 can be a reference lead. Other configurations are possible with additional leads within the same package or at different points on the patient's body. Using abundle ECG sensor 206 can advantageously enable a single cable connection via the cable 205 to thecuff 212 b. Similarly, an acoustical sensor can be included in theECG sensor 206 to advantageously reduce the overall complexity of the on-body assembly. - The cable 205 in
FIG. 2B can connect two sensors to thecuff 212 b, namely theECG sensor 206 and theacoustic sensor 204 b. Although not shown, the cable 205 can further connect an optical ear sensor to theacoustic sensor 204 b in some embodiments, optionally replacing the fingeroptical sensor 202 b. The cable 205 shown inFIG. 2B can have all the features described above with respect toFIG. 2A . - Although not shown, in some embodiments, any of the sensors, cuffs, wireless sensors, or patient monitors described herein can include one or more accelerometers or other motion measurement devices (such as gyroscopes). For example, in
FIG. 2B , one or more of theacoustic sensor 204 b, theECG sensor 206, thecuff 212 b, the patient monitor 216 b, and/or theoptical sensor 202 b can include one or more motion measurement devices. A motion measurement device can be used by a processor (such as in the patient monitor 216 b or other device) to determine motion and/or position of a patient. For example, a motion measurement device can be used to determine whether a patient is sitting up, lying down, walking, or the like. - Movement and/or position data obtained from a motion measurement device can be used to adjust a parameter calculation algorithm to compensate for the patient's motion. For example, a parameter measurement algorithm that compensates for motion can more aggressively compensate for motion in response to high degree of measured movement. When less motion is detected, the algorithm can compensate less aggressively. Movement and/or position data can also be used as a contributing factor to adjusting parameter measurements. Blood pressure, for instance, can change during patient motion due to changes in blood flow. If the patient is detected to be moving, the patient's calculated blood pressure (or other parameter) can therefore be adjusted differently than when the patient is detected to be sitting.
- A database can be assembled that includes movement and parameter data (raw or measured parameters) for one or more patients over time. The database can be analyzed by a processor to detect trends that can be used to perform parameter calculation adjustments based on motion or position. Many other variations and uses of the motion and/or position data are possible.
- Although the patient monitoring systems described herein, including the
systems FIGS. 3A and 3B ), can be carried by the patient (e.g., via a shoulder strap or handle), or can be placed on the patient's bed next to the patient, among other possible locations. - Additionally, various features shown in
FIGS. 2A and 2B can be changed or omitted. For instance, the wireless transceiver 216 can be attached to the cuff 212 without the use of thepocket 214. For example, the wireless transceiver can be sown, glued, buttoned or otherwise attached to the cuff using any various known attachment mechanisms. Or, the wireless transceiver 216 can be directly coupled to the patient (e.g., via an armband) and the cuff 212 can be omitted entirely. Instead of a cuff, the wireless transceiver 216 can be coupled to a non-occlusive blood pressure device. Many other configurations are possible. -
FIGS. 3A and 3B illustrate further embodiments of apatient monitoring system FIG. 3A depicts a tetheredpatient monitoring system 300A, whileFIG. 3B depicts a wirelesspatient monitoring system 300B. Thepatient monitoring systems - Referring to
FIG. 3A , the acoustic andECG sensors FIG. 2 are again shown coupled to thepatient 201. As above, thesesensors cable 250 is coupled to ajunction device 230 a instead of to a blood pressure cuff. In addition, theoptical sensor 202 b is coupled to thepatient 201 and to thejunction device 230 a via acable 207. Thejunction device 230 a can anchor thecable 205 b to the patient 201 (such as via the patient's belt) and pass through any signals received from thesensors patient monitor 240 via asingle cable 232. - In some embodiments, however, the
junction device 230 a can include at least some front-end signal processing circuitry. In other embodiments, thejunction device 230 a also includes a processor for processing physiological parameter measurements. Further, thejunction device 230 a can include all the features of the patient monitor 216 b in some embodiments, such as providing a display that outputs parameters measured from data obtained by thesensors - In the depicted embodiment, the patient monitor 240 is connected to a
medical stand 250. The patient monitor 240 includesparameter measuring modules 242, one of which is connected to thejunction device 230 a via thecable 232. The patient monitor 240 further includes adisplay 246. Thedisplay 246 is a user-rotatable display in the depicted embodiment. - Referring to
FIG. 3B , thepatient monitoring system 300B includes nearly identical features to thepatient monitoring system 300A. However, thejunction device 230 b includes wireless capability, enabling thejunction device 230 b to wirelessly communicate with the patient monitor 240 and/or other devices. -
FIGS. 4A and 4B illustrate embodiments ofpatient monitoring systems cable connection systems 410 for connecting sensors to a patient monitor 402. Like the cable 205 described above, thesecable connection systems 410 can advantageously enhance patient mobility and comfort. - Referring to
FIG. 4A , thepatient monitoring system 400A includes a patient monitor 402 a that measures physiological parameters based on signals obtained fromsensors optical ear sensor 412 and anacoustic sensor 420 in the embodiment shown. Theoptical ear sensor 412 can include any of the features of the optical sensors described above. Likewise, theacoustic sensor 420 can include any of the features of the acoustic sensors described above. - The
optical ear sensor 412 can be shaped to conform to the cartilaginous structures of the ear, such that the cartilaginous structures can provide additional support to thesensor 412, providing a more secure connection. This connection can be particularly beneficial for monitoring during pre-hospital and emergency use where the patient can move or be moved. In some embodiments, theoptical ear sensor 412 can have any of the features described in U.S. application Ser. No. 12/658,872, filed Feb. 16, 2010, entitled “Ear Sensor,” the disclosure of which is hereby incorporated by reference in its entirety. - An
instrument cable 450 connects the patient monitor 402 a to thecable connection system 410. Thecable connection system 410 includes asensor cable 440 connected to theinstrument cable 250. Thesensor cable 440 is bifurcated into twocable sections individual sensors anchor 430 a connects thesensor cable 440 andcable sections anchor 430 a can include an adhesive for anchoring thecable connection system 410 to the patient, so as to reduce noise from cable movement or the like. Advantageously, thecable connection system 410 can reduce the number and size of cables connecting the patient to a patient monitor 402 a. Thecable connection system 410 can also be used to connect with any of the other sensors, patient-worn monitors, or wireless devices described above. -
FIG. 4B illustrates thepatient monitoring system 400B, which includes many of the features of themonitoring system 400A. For example, anoptical ear sensor 412 and anacoustic sensor 420 are coupled to the patient. Likewise, thecable connection system 410 is shown, including thecable sections anchor 430 b. In the depicted embodiment, thecable connection system 410 communicates wirelessly with apatient monitor 402 b. For example, theanchor 430 b can include a wireless transceiver, or a separate wireless dongle or other device (not shown) can couple to theanchor 430 b. Theanchor 430 b can be connected to a blood pressure cuff, wireless transceiver, junction device, or other device in some embodiments. -
FIG. 5 illustrates a more detailed embodiment of awireless transceiver 516. Thewireless transceiver 516 can have all of the features of thewireless transceiver 516 described above. For example, thewireless transceiver 516 can connect to a blood pressure cuff and to one or more physiological sensors, and thetransceiver 516 can transmit sensor data to a wireless receiver. - The depicted embodiment of the
transceiver 516 includes ahousing 530, which includesconnectors 552 for sensor cables (e.g., for optical, acoustic, ECG, and/or other sensors) and aconnector 560 for attachment to a blood pressure cuff or other patient-wearable device. Thetransceiver 516 further includes anantenna 518, which although shown as an external antenna, can be internal in some implementations. - In addition, the
transceiver 516 includes adisplay 554 that depicts values of various parameters, such as systolic and diastolic blood pressure, SpO2, and respiratory rate (RR). Thedisplay 554 can also display trends, alarms, and the like. Thetransceiver 516 can be implemented with thedisplay 554 in embodiments where thetransceiver 516 also acts as a patient monitor. Thetransceiver 516 further includescontrols 556, which can be used to manipulate settings and functions of thetransceiver 516. -
FIGS. 6A through 6C illustrate embodiments of wireless patient monitoring systems 600.FIG. 6A illustrates apatient monitoring system 600A that includes awireless transceiver 616, which can include the features of any of the transceivers 216, 216 described above. Thetransceiver 616 provides a wireless signal over awireless link 612 to apatient monitor 620. The wireless signal can include physiological information obtained from one or more sensors, physiological information that has been front-end processed by thetransceiver 616, or the like. - The patient monitor 620 can act as the
wireless receiver 220 ofFIG. 2 . The patient monitor 620 can process the wireless signal received from thetransceiver 616 to obtain values, waveforms, and the like for one or more physiological parameters. The patient monitor 620 can perform any of the patient monitoring functions described above with respect toFIGS. 2 through 5 . - In addition, the patient monitor 620 can provide at least some of the physiological information received from the
transceiver 616 to a multi-patient monitoring system (MMS) 640 over anetwork 630. TheMMS 640 can include one or more physical computing devices, such as servers, having hardware and/or software for providing the physiological information to other devices in thenetwork 630. For example, theMMS 640 can use standardized protocols (such as TCP/IP) or proprietary protocols to communicate the physiological information to one or more nurses' station computers (not shown) and/or clinician devices (not shown) via thenetwork 630. In one embodiment, theMMS 640 can include some or all the features of the MMS described in U.S. Publication No. 2008/0188760, referred to above. - The
network 630 can be a LAN or WAN, wireless LAN (“WLAN”), or other type of network used in any hospital, nursing home, patient care center, or other clinical location. In some implementations, the network 210 can interconnect devices from multiple hospitals or clinical locations, which can be remote from one another, through the Internet, one or more Intranets, a leased line, or the like. Thus, theMMS 640 can advantageously distribute the physiological information to a variety of devices that are geographically co-located or geographically separated. -
FIG. 6B illustrates another embodiment of apatient monitoring system 600B, where thetransceiver 616 transmits physiological information to abase station 624 via thewireless link 612. In this embodiment, thetransceiver 616 can perform the functions of a patient monitor, such as any of the patient monitor functions described above. Thetransceiver 616 can provide processed sensor signals to thebase station 624, which forwards the information on to theMMS 640 over thenetwork 630. -
FIG. 6C illustrates yet another embodiment of apatient monitoring system 600B, where thetransceiver 616 transmits physiological information directly to theMMS 640. TheMMS 640 can include wireless receiver functionality, for example. Thus, the embodiments shown inFIGS. 6A through 6C illustrate that thetransceiver 616 can communicate with a variety of different types of devices. -
FIG. 7 illustrates an embodiment of aphysiological parameter display 700. Thephysiological parameter display 700 can be output by any of the systems described above. For instance, thephysiological parameter display 700 can be output by any of the wireless receivers, transceivers, or patient monitors described above. Advantageously, in certain embodiments, thephysiological parameter display 700 can display multiple parameters, including noninvasive blood pressure (NIBP) obtained using both oscillometric and non-oscillometric techniques. - The
physiological parameter display 700 can display any of the physiological parameters described above, to name a few. In the depicted embodiment, thephysiological parameter display 700 is shown displayingoxygen saturation 702,heart rate 704, andrespiratory rate 706. In addition, thephysiological parameter display 700 displaysblood pressure 708, including systolic and diastolic blood pressure. - The
display 700 further shows aplot 710 of continuous or substantially continuous blood pressure values measured over time. Theplot 710 includes atrace 712 a for systolic pressure and atrace 712 b for diastolic pressure. Thetraces traces - Periodically, oscillometric blood pressure measurements (sometimes referred to as Gold Standard NIBP) can be taken, using any of the cuffs described above. These measurements are shown by
markers 714 on theplot 710. By way of illustration, themarkers 714 are “X's” in the depicted embodiment, but the type ofmarker 714 used can be different in other implementations. In certain embodiments, oscillometric blood pressure measurements are taken at predefined intervals, resulting in the measurements shown by themarkers 714. - In addition to or instead of taking these measurements at intervals, oscillometric blood pressure measurements can be triggered using ICI techniques, e.g., based at least partly on an analysis of the noninvasive blood pressure measurements indicated by the
traces plot 710, thedisplay 700 can provide a clinician with continuous and oscillometric blood pressure information. -
FIG. 8 illustrates another embodiment of apatient monitoring system 800. The features of thepatient monitoring system 800 can be combined with any of the features of the systems described above. Likewise, any of the features described above can be incorporated into thepatient monitoring system 800. Advantageously, in the depicted embodiment, thepatient monitoring system 800 includes acable hub 806 that enables one or many sensors to be selectively connected and disconnected to thecable hub 806. - Like the patient monitoring systems described above, the
monitoring system 800 includes acuff 810 with apatient device 816 for providing physiological information to amonitor 820 or which can receive power from a power supply (820). Thecuff 810 can be a blood pressure cuff or merely a holder for thepatient device 816. Thepatient device 816 can instead be a wireless transceiver having all the features of the wireless devices described above. - The
patient device 816 is in coupled with anoptical finger sensor 802 viacable 807. Further, thepatient device 816 is coupled with thecable hub 806 via acable 805 a. Thecable hub 806 can be selectively connected to one or more sensors. In the depicted embodiment, example sensors shown coupled to thecable hub 806 include anECG sensor 808 a and abrain sensor 840. TheECG sensor 808 a can be single-lead or multi-lead sensor. Thebrain sensor 840 can be an electroencephalography (EEG) sensor and/or an optical sensor. An example of EEG sensor that can be used as thebrain sensor 840 is the SEDLine™ sensor available from Masimo® Corporation of Irvine, Calif., which can be used for depth-of-anesthesia monitoring among other uses. Optical brain sensors can perform spectrophotometric measurements using, for example, reflectance pulse oximetry. Thebrain sensor 840 can incorporate both an EEG/depth-of-anesthesia sensor and an optical sensor for cerebral oximetry. - The
ECG sensor 808 a is coupled to anacoustic sensor 804 and one or more additional ECG leads 808 b. For illustrative purposes, fouradditional leads 808 b are shown, for a 5-lead ECG configuration. In other embodiments, one or twoadditional leads 808 b are used instead of four additional leads. In still other embodiments, up to at least 12 leads 808 b can be included. Acoustic sensors can also be disposed in theECG sensor 808 a and/or lead(s) 808 b or on other locations of the body, such as over a patient's stomach (e.g., to detect bowel sounds, thereby verifying patient's digestive health, for example, in preparation for discharge from a hospital). Further, in other embodiments, theacoustic sensor 804 can connect directly to thecable hub 806 instead of to theECG sensor 808 a. - As mentioned above, the
cable hub 806 can enable one or many sensors to be selectively connected and disconnected to thecable hub 806. This configurability aspect of thecable hub 806 can allow different sensors to be attached or removed from a patient based on the patient's monitoring needs, without coupling new cables to themonitor 820. Instead, a single, light-weight cable 832 couples to themonitor 820 in certain embodiments, or wireless technology can be used to communicate with the monitor 820 (see, e.g.,FIG. 1 ). A patient's monitoring needs can change as the patient is moved from one area of a care facility to another, such as from an operating room or intensive care unit to a general floor. The cable configuration shown, including thecable hub 806, can allow the patient to be disconnected from a single cable to themonitor 820 and easily moved to another room, where a new monitor can be coupled to the patient. Of course, themonitor 820 may move with the patient from room to room, but thesingle cable connection 832 rather than several can facilitate easier patient transport. - Further, in other embodiments, the
cuff 810 and/orpatient device 816 need not be included, but thecable hub 806 can instead connect directly to the monitor wirelessly or via a cable. Additionally, thecable hub 806 or thepatient device 816 may include electronics for front-end processing, digitizing, or signal processing for one or more sensors. Placing front-end signal conditioning and/or analog-to-digital conversion circuitry in one or more of these devices can make it possible to send continuous waveforms wirelessly and/or allow for a small, more user-friendly wire (and hence cable 832) routing to themonitor 820. - The
cable hub 806 can also be attached to the patient via an adhesive, allowing thecable hub 806 to become a wearable component. Together, the various sensors, cables, andcable hub 806 shown can be a complete body-worn patient monitoring system. The body-worn patient monitoring system can communicate with apatient monitor 820 as shown, which can be a tablet, handheld device, a hardware module, or a traditional monitor with a large display, to name a few possible devices. - Depending on the embodiment, certain acts, events, or functions of any of the methods described herein can be performed in a different sequence, can be added, merged, or left out all together (e.g., not all described acts or events are necessary for the practice of the method). Moreover, in certain embodiments, acts or events can be performed concurrently, e.g., through multi-threaded processing, interrupt processing, or multiple processors, rather than sequentially.
