An electronic analgesia/anesthesia apparatus is provided for the administration of a mixture of gases. This said apparatus has separate controls for independently increasing or decreasing the flow rate of each particular gas to be delivered thereby and includes an electrical circuit operatively connected to each control for driving a display indicative of the flow rate of the gas and a percentage calculator connected to each individual control for calculating the percentage of a particular gas with respect to the total gas flow and for displaying same; high and low pressure limit alarms and a pressure responsive safety control are included.

Analgesia/anesthesia apparatus comprising in combination the following: separate gas flow lines and associated means for connection of said lines to separate supplies of at least two gases; means, in each said line, for varying the rate of gas flow through said line; encoder means, coupled to said gas flow rate varying means, for encoding the state thereof; first means for visual display responsive to the output of said encoder means; calculator means, coupled to said gas flow rate varying means, for generating signals representative of the ratio of one of said rates of gas flows to the total gas rate of flow; and separate second means for visual display of said ratio responsive to said generated signals.
