Outpatient health emergency warning system
First Claim
1. A medical system for sensing a physiological state requiring defibrillation in a patient, the system comprising:
- a baseline signal sensor to generate a baseline signal relating to an activity level of a patient over time, the activity level determined based on one or more of motion of the patient or electrical activity of a heart of the patient;
a physiological parameter measuring device comprising at least one parameter sensor having a higher power consumption than the baseline signal sensor, the at least one parameter sensor having a low power state during which the physiological parameter measuring device sleeps and a higher power state during which the at least one parameter sensor outputs at least one physiological parameter signal indicative of at least one physiological parameter of the patient; and
a processor configured to;
control the at least one parameter sensor to enter the higher power state to output the physiological parameter signal responsive to a trigger event determined from the baseline signal, the trigger event comprising one or more of reduction of the motion of the patient or reduction of the electrical activity of the heart of the patient below predetermined threshold boundaries over time; and
assess the at least one physiological parameter signal to determine whether a physiological state requiring defibrillation in a patient is present.

Abstract
A medical system for sensing a physiological state requiring defibrillation in a patient. The system comprising: a low power sensor, a physiological parameter measuring device, and a processor. The low power sensor generating a baseline signal relating to a physiological status of said patient. The physiological parameter measuring device comprising at least one higher power sensor configured to output at least one physiological parameter signal indicative of at least one physiological parameter of said patient. The processor assessing the baseline signal and determining if the physiological status is outside predetermined threshold boundaries.

11. A medical system for sensing a physiological state requiring defibrillation in a patient, the system comprising:
-
a low power sensor including control logic configured to generate an interrupt signal upon determining that a physiological status of a patient, as measured by the low power sensor, is outside predetermined threshold boundaries; a physiological parameter measuring device comprising at least one parameter sensor, the at least one parameter sensor having a higher power consumption than the low power sensor, the at least one parameter sensor having a low power state during which the physiological parameter measuring device sleeps and a higher power state during which the at least one parameter sensor outputs at least one physiological parameter signal indicative of at least one physiological parameter of the patient; and a master control system configured to; control the at least one parameter sensor to enter the higher power state to output the physiological parameter signal responsive to the interrupt signal generated by the low power sensor; and assess the at least one physiological parameter signal to determine whether a physiological state that requires defibrillation in the patient is present; wherein; the master control system has an active mode and a sleep mode; and the interrupt signal is configured to trigger the master control system to enter into the active mode.
