Abstract
A method and apparatus for treating patients suffering from one or more of the conditions of cardiac arrest, shock, respiratory failure, hypothermia, hyperthermia and head injury. Chest tubes are inserted through respective holes in each hemithorax of the patient and attached to a gas source and an exhaust pump with connections and valves for alternately inflating and deflating a patient's thoracic cavity with a gas. A gas regulator, including heat exchanger, is interposed between the gas source and the tubes for warming or cooling the gas, and an electrode is mounted on the tubes and connected through a wire to electronic medical equipment. Collapsed seals are formed annularly around the chest tube and expanded after insertion to form a gas seal between the tube and the chest wall. The seal may be a bladder expanded by filling with a fluid or a wire mesh receptacle which is mechanically expanded and can also serve as the electrode.
