## Abstract

A resuscitation system for use by a rescuer for resuscitating a patient, comprising at least two high-voltage defibrillation electrodes, a first electrical unit comprising circuitry for providing resuscitation prompts to the rescuer, a second electrical unit separate from the first unit and comprising circuitry for providing defibrillation pulses to the electrodes, and circuitry for providing at least one electrical connection between the first and second units. In another aspect, at least two electrical therapy electrodes adapted to be worn by the patient for extended periods of time, circuitry for monitoring the ECG of the patient, an activity sensor adapted to be worn by the patient and capable of providing an output from which the patient's current activity can be estimated, and at least one processor configured for estimating the patient's current activity by analyzing the output of the activity sensor, analyzing the ECG of the patient, and determining whether electrical therapy should be delivered to the electrodes.

## Claims

### Claim 1

A resuscitation system for use by a rescuer for resuscitating a patient, comprising:
at least two high-voltage defibrillation electrodes;
a first electrical unit comprising circuitry for providing resuscitation prompts to the rescuer;
a second electrical unit separate from the first unit and comprising circuitry for providing defibrillation pulses to the electrodes;
circuitry for providing at least one electrical connection between the first and second units,
an activity sensor adapted to be worn by the patient and capable of providing an output from which the patient's current activity can be estimated, wherein the patient's current activity comprises overall body activity rather than cardiac activity; and
at least one processor configured for estimating the patient's current activity by analyzing the output of the activity sensor.

### Claim 2 (depends on 1)

The resuscitation system of claim 1 wherein the at least one processor is located in the first unit.

### Claim 3 (depends on 2)

The resuscitation system of claim 2 wherein at least some of the resuscitation prompts delivered by the first unit are dependent on the estimated current activity of the patient.

### Claim 4 (depends on 3)

The resuscitation system of claim 3 wherein the current activity comprises whether the patient is lying on his back, and at least one resuscitation prompt issued when the patient is not on his back is an instruction to roll the patient on their back prior to beginning CPR.
