ABSTRACT A self-contained portable ventilator/resuscitator which can be operated from either an internal power source, or in the event that the power source fails, can be manually operated to provide the patient with a supply of filtered ambient gases. The ventilator/resuscitator includes a housing (12) in which is mounted a chlorate candle (36), a filter (38), a pump (32), and control means (34). The pump is caused to be operated by the chlorate candle and will cause ambient gases to be drawn into the filter to be mixed with the output of the candle for subsequent delivery to the patient. The device further includes an accumulator (14) which, during normal operation, stores excess gases during the expiratory cycle, and, in the event that the chlorate candle ceases operation, can be manually operated through movement of the handle (90) to either draw gases into the accumulator through filter (38) or to force the filtered gases into the lungs of the patient.
