Cardiopulmonary resuscitator, defibrillator and monitor
First Claim
1. A cardiac compressor and defibrillator comprising in combination:
- a reciprocatable cardiac compressor means for cyclically compressing a patient'"'"'s chest;
said compressor means including a base for positioning behind the patient'"'"'s back posterior to the patient'"'"'s heart;
said compressor means including a cardiac compressor pad for positioning anterior to the patient'"'"'s heart, said compressor pad being actuated by said compressor means for compressing the patient'"'"'s heart between said compressor pad and said base;
an anterior electrode disposed on said compressor pad for compression between said compressor pad and the patient'"'"'s sternum;
a posterior electrode disposed on said base for compression between said base and the patient'"'"'s back;
a cardiac defibrillator means connected to said anterior and posterior electrodes for establishing an electric current therebetween; and
a means for synchronizing said defibrillator means and said compressor means whereby a defibrillating current is applied to the patient'"'"'s heart only during compression of a patient'"'"'s heart.

Abstract
A reciprocal cardiac compressor is provided for cyclically compressing a patient'"'"'s chest. Preferably a resuscitator is also provided for ventilating the patient'"'"'s lungs. The compressor includes a reciprocal compressor pad positioned anterior to the patient'"'"'s heart and a stationary base positioned posterior to the patient'"'"'s heart. An anterior electrode is disposed on the face of the compressor pad for compression between the compressor pad and the patient'"'"'s sternum and a posterior electrode is disposed on the base of the compressor for compression between the base and the patient'"'"'s back. A cardiac defibrillator is connected between anterior and posterior electrodes for establishing a defibrillating electric current therebetween. A monitor is connected to the anterior and posterior electrodes for monitoring the electrical activity of the patient'"'"'s heart. Means for snychronizing the defibrillator and the compressor is provided comprising a pressure sensitive switch for synchronizing the defibrillator and compressor such that defibrillating current is applied to the patient'"'"'s heart only during a systolic portion of the compression cycle of the compressor.
