In a method and apparatus for controlling breathing of a patient, momentary compliance is calculated during an inspiration. The calculated momentary compliance is then compared to a threshold value. If momentary compliance is less than the threshold value during a first interval, positive end expiratory pressure is reduced for subsequent breathing cycles so momentary compliance is greater than the threshold value during the first interval. If momentary compliance is less than the threshold value during a second interval, the ratio between inspiration time and expiration time, as well as the breathing rate, is changed so momentary compliance is greater than the threshold value during the second interval, at the same time as a pre-defined minute volume is generated.
