ABSTRACT:
An automatic resuscitation device for administering a breathable gas under pressure to a patient by an operator where all operating controls and alarms are powered by the pressurized gas in a manual override mode, a patient breathing deemed override mode, and an automatic mode. The device uses no power source other than the pressurized gas to drive alarms and the entire control system. The controls include pneumatic valves and pneumatic alarms as follows: a breathing circuit integrity alarm for notifying the operator that an integrity condition has been detected; a power fail alarm for notifying the operator that the source of pressurized gas has a pressure below a selected source input valve; and pressure relief alarm for notifying the operator that the patient's airway is above the selected pressure relief value.
