An apparatus for controlling the oxygen concentration in a respirable mixture of air and oxygen issuing from a mixer (6) for delivery to a patient (4) in a chamber such as an incubator (2) includes a device, for example, an intravascular electrode for generating a signal corresponding to the oxygen concentration in the blood of the patient (4). The signal is received by a control unit (12) having a shaft (14) which enters the mixer (6), the angular position of which shaft (14) controls the percentage of oxygen in the gas mixture issuing from the mixer. |
