CPR compression device and method
Improved automatic chest compression systems which use constricting belts, repeatedly inflating bladders, or reciprocating pistons to compress the chest. A bladder is placed between the chest and the particular mechanism used to compress the chest during CPR. The bladder maximizes the effectiveness of chest compressions.
1. A system for performing CPR on a patient, said system comprising:
a chest compression means comprising a belt adapted to be disposed at least partially about the chest of the patient and a means for repetitively tightening the belt at a resuscitative rate, said means for repetitively tightening the belt operably connected to the belt;
a bladder disposed between the chest compression means and the chest of the patient, wherein the bladder is divided to form a left lateral chamber in fluid communication with a central chamber in fluid communication with a right lateral chamber, and wherein each chamber contains a pressure-transmitting medium, and the bladder is disposed relative to the belt during use such that the bladder is between the belt and the chest of the patient and the central chamber is disposed over the sternum of the patient.
