Abstract

A self-contained portable single patient ventilator/resuscitator of the type which has a timed cycle of operation, but which a patient can override in response to his physiological needs. The ventilator/resuscitator has a power source in the form of a chemical oxygen generator (18 or 132), fluid operated delivery means associated with the oxygen source, and control means. The delivery means includes pump means (28 or 122) associated with an ambient air filter (32 or 120), a two position valve shiftable between inspiratory and expiratory modes, an output tube (42 or 130) and a mask (10 or 110) and head harness (12 or 112). When the delivery means is in the inspiratory mode at least a portion of the oxygen output is delivered to the patient (14 or 114) and when the delivery means is in the expiratory mode at least a portion of the oxygen output is delivered to an accumulator (54 or 124). The control means (24 or 186, 188, 190, 192) will cause the valve means (22 or 128) to cycle between its inspiratory and expiratory positions in a timed cycle established by timing modules (88, 89 or 188, 190). The control means additionally includes pressure sensing devices (90, 92 or 202) which are capable of causing the valve means to be shifted to an inspiratory mode when the patient initiates an inspiratory effort, and which are also capable of causing the valve means to be shifted to an expiratory mode when the pressure to the patient exceeds its set peak pressure. <IMAGE>
