Abstract

A system for tracking a patient'"'"'s physiological status and detecting and predicting negative physiological events, with a detecting system and a remote monitoring system. The detecting system includes a plurality of sensors that provide an indication of at least one physiological event of a patient, and a wireless communication device coupled to the plurality of sensors, and configured to transfer patient data from the plurality of sensors to a remote monitoring system. The a remote monitoring system coupled to the wireless communication device, wherein during a registration period, the detecting system being activated for a first time and communicating with the remote monitoring system to register the detecting system and activate data logging.

Claims

1. A system for tracking a patient'"'"'s physiological status and detecting and predicting negative physiological events, comprising:

a detecting system, including;

a plurality of sensors that provide an indication of at least one physiological event of a patient,

a wireless communication device coupled to the plurality of sensors, and configured to transfer patient data from the plurality of sensors to a remote monitoring system; and

a remote monitoring system coupled to the wireless communication device, wherein during a registration period, the detecting system being activated for a first time and communicating with the remote monitoring system to register the detecting system and activate data logging.

2. The system of claim 1, wherein during the registration period the detecting system titrates a sensitivity of each of a sensor of the plurality of sensors.

3. The system of claim 1, wherein the system is configured to automatically detect events.

4. The system of claim 3, wherein the system automatically detects events by at least one of, high noise states, low noise states, physiological quietness, sensor continuity and compliance.

5. The system of claim 1, wherein in response to a detected physiological event, patient states are identified.

6. The system of claim 5, wherein patient states include, physiological quietness, rest, relaxation, agitation, movement, lack of movement and a higher level of patient activity.

7. The system of claim 1, wherein each of a sensor is selected from at least one of, an accelerometer, a heart rate sensor, including ECG electrodes, a heart rate sensor, including an ECG sensor, a heart rhythm sensor, a body surface temperature sensor, an ambient temperature sensor, a bioimpedance sensor, a posture sensor, a respiration sensor, a clock, an activity sensor, an optical sensor, a blood pressure sensor and a weight sensor.

8. The system of claim 7, wherein the activity sensor is selected from at least one of, ball switch, accelerometer, minute ventilation, HR, bioimpedance noise, skin temperature/heat flux, BP, muscle noise and posture.

9. The system of claim 1, further comprising:

a sensor continuity indicator.

10. The system of claim 9, wherein the sensor continuity indicator is configured to test to determine if a sensor is at least one of, in contact with a skin surface, has failed and has poor performance.

11. The system of claim 1, further comprising:

a compliance indicator.

12. The system of claim 11, wherein the compliance indicator determines if a sensor is coupled to a skin surface to provide a sensor output.

13. The system of claim 11, wherein the compliance indicator is an intermittent tester to determine that sensor continuity is intact.

14. The system of claim 11, wherein the compliance indicator is configured to respond to loss of sensor continuity with an alarm and notify a patient or third parry to take an action.

15. The system of claim 14, wherein the alarm provides a visual, auditory or electronic signal.

16. The system of claim 14, wherein the alarm notifies at least one of, the patient, a clinic and a health care provider.

17. The system of claim 11, wherein the compliance indicator detects if a patient is not using the detecting system.

18. The system of claim 17, wherein in response to the compliance indicator indicating that a patient is not in compliance, a signal is used to force compliance.

19. The system of claim 1, wherein the detecting system communicates with the remote monitoring system periodically or in response to a trigger event.

20. The system of claim 19, wherein the trigger event is selected from at least one of, time of day, if a memory is full, if an action is patient initiated, if an action is initiated from the remote monitoring system, a diagnostic event of the monitoring system, an alarm trigger, a mechanical trigger on a patch and a patch replacement.
