Abstract
An arrangement for determining an opening pressure of a lung has a regulating unit which can deliver inspiration pulses to a patient's lung system, a blood gas analyzer for measuring the partial pressure of oxygen in the blood of the patient's circulatory system, and a control unit for determining an opening pressure based on the measured P.sub.a O.sub.2. When the measured P.sub.a O.sub.2 exceeds a predetermined threshold, the lung have opened sufficiently and a pressure value is correlated to the measured P.sub.a O.sub.2 and defined as the opening pressure.
