A method for controlling a breathing apparatus is described. In the method, momentary compliance (38, 44, 46) is calculated during an inspiration (40A, 40B). The calculated momentary compliance (38, 44, 46) is then compared to a threshold value (42). If momentary compliance (38) is less than the threshold value (42) during a first interval (40A), positive end expiratory pressure (PEEP) is reduced for subsequent breathing cycles so momentary compliance is greater than the threshold value (42) during the first interval (40A). If momentary compliance (44) is less than the threshold value (42) during a second interval (40B), 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 (42) during the second interval (40B), at the same time as a pre-defined minute volume is generated. <IMAGE>
