LIQUID VENTILATION METHOD AND APPARATUS

摘要

This invention is a method and apparatus for liquid ventilation to increase the efficacy of cardiopulmonary resuscitation (CPR). The method includes 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 without a mechanical respirator. An advantage is provided by supplying a continuous flow of liquid (or gaseous) ventilation medium throughout the entire chest compression/re-expansion cycle, accelerating both gas exchange and cooling or warming of the patient or animal subject. In the apparatus (100), breathing liquid returns from a patient via tube (101) and is supplied via tube (190), tubes (101, 190) being connected to an endotracheal tube (200). The apparatus includes a reservoir (110), an oxygenator (120), and a heater (130).
