Abstract
A control device for an artificial respirator includes a timebase circuit (B) on which the frequency F=1/T and the ratio I/E of the inhalation to exhalation times are selected, a mixer (M) on which the total gas supply volume and the proportion of oxygen are selected, and two control signal generators (G.sub.O, G.sub.A) for operating two solenoid-controlled valves (EV.sub.A, EV.sub.O) for the air and oxygen. It is possible to select each one of the four variable parameters independently of all the others.
