Abstract An anesthesia ventilator (10) is disclosed for controlling the flow of air and/or oxygen through a plur- ality of binary weighted valves (34-38) from a fluid regulator source (27) to a bellows assembly (14). Directly-set minute volume, breath rate and inspiration to expiration ratio controls (11, 12, 13) operate elec- tronic circuitry (23) which adjusts the magnitude of the flow, the tidal volume and the inhalation to exhalation times. The circuitry (23) includes alarm detecting devices (15-17) 32, 180, 182) for alerting personnel that a patient should be ventilated manually, that a patient is disconnected from the instrument, that control settings exceed specifications for the instrument, that undesired low gas pressure exists and that actual inspiration to expiration is less than that of the control setting. Flow and tidal volume limiting apparatus (72, 129) is provided, together with sigh circuitry (126) and devices (105, 104) for correcting for altitude and gas parameters. Levy-Rusz 3-1
