ABSTRACT:
An apparatus and method for controlling a respirating gas supply system responsive to a patient's respiration. The ratio of the time of the gas supply valve open to the time of the valve closed is measured and an automatic oxygen flow override is provided if the ratio is outside a set range. Various indicators quickly indicate to the operator what system or systems have failed and/or the condition of the patient's respiration. The apparatus can operate in two modes: a pre-flush mode which would begin gas flow to the patient at the end of exhalation and end gas flow at the end of inhalation and an inhalation mode which would begin gas flow at the beginning of inhalation and end gas flow at the end of inhalation.
