A method and apparatus for resuscitating the cardiac/pulmonary activity of a patient includes the use of pneumatically controlled inflatable/deflatable cuffs secured over the patient's legs and abdomen and optionally the chest. The cuffs are preferably inflated and deflated at a cyclical rate of 10-40 cycles/min. with the inflation/deflation mode of the chest cuff, if used, being out-of-phase with the operation of the abdominal cuff. A ventilator and face mask may be used to supply breathable air to the patient's airway in conjunction with the cyclical operation of the cuffs.

Cardiac/pulmonary resuscitation method and apparatus

A canister containing one or more working compounds formed of a peroxide and/or superoxide of one or more metals of the alkali and alkaline-earth metal groups such as KO.sub.2 and CaO.sub.2 and a moisture releasing material such as wetted activated charcoal is utilized to replenish the oxygen and absorb the carbon dioxide in exhaled air. The canister may be used in a closed or semi-closed circuit breathing system worm by a user such as a fireman, miner etc.

Method and apparatus for revitalizing exhaled air

A resuscitation breathing apparatus includes a high pressure source of breathable gas and an inhalation chamber having an inlet and an outlet. A face mask is connected to the outlet of the inhalation chamber. Inhalation and exhalation check valves in the face mask allow air to enter and exit a patient's lungs. An inhalation valve, connected between the inhalation chamber and the high pressure source, is controlled to open and close the inhalation valve when the pressure reaches first and second values, respectively. The inhalation chamber is vented to lower the pressure within the chamber after the inhalation valve is closed. The apparatus further includes a chest compressor in the form of an inflatable cuff for applying pressure to the patient's lungs during the exhalation phase. The cuff is inflated by gas from the high pressure source when the inhalation valve is closed.
