Abstract
A method and apparatus utilize liquid ventilation to increase the efficacy of cardiopulmonary resuscitation (CPR). The method involves replacing gas in the lungs with an oxygen and carbon dioxide carrying liquid to eliminate the decreased pumping efficiency of the heart seen during conventional or active compression-decompression (ACD) closed-chest CPR. A further advantage during ACD-CPR is the ability to perform liquid ventilation without a mechanical respirator. A further advantage is provided by supplying a continuous flow of liquid (or gaseous) ventilation medium throughout the entire chest compression/re-expansion cycle, dramatically accelerating both gas exchange and cooling or warming of the patient or animal subject.
