ABSTRACT:
An integrated system for cardiopulmonary resuscitation and circulation support comprising chest compression means adapted to be positioned over the patient's sternum and operable to compress the sternum at desired intervals and to a desired degree, lung ventilating means including (1) a high pressure ventilator for ventilating simultaneously with chest compression; (2) a low pressure ventilator for inflating the lungs at low pressure between a selected number of compression cycles; and (3) a negative pressure ventilator for deflating the lungs between chest compressions; valve means for selectively operating only one of the indicated ventilators at any one time; means for restricting the abdomen to exert pressure on the abdominal wall; and control means for selectively operating the chest compression means, the lung ventilating means, valve means and abdomen restriction means in a selected sequence and for the period of time desired.
