Abstract

A resuscitation system 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.

First claim

What is claimed is:

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;
a 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 a patient initiated current activity can be estimated, wherein the patient initiated current activity comprises overall body activity rather than cardiac activity; and
at least one processor configured for estimating the patient initiated current activity by analyzing the output of the activity sensor.

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

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

4. The resuscitation system of claim 3 wherein the patient initiated 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.
