Abstract: A blower pressure source has been integrated into a vest cardiopulmonary resuscitation (CPR) system. The vest includes a bladder that cyclically inflates and deflates to provide automatic CPR to a patient in cardiac arrest or needing circulatory assistance to a patient with a beating but weakened heart. The blower continuously provides air at relatively low pressure to inflate a bladder in the vest. The maximum pressure of the blower corresponds to the desired peak vest pressure. A relatively simple valve, solenoid and timing controller is used to apply the blower air in cycles to inflate the bladder.
