Respirator techniques are described for measuring the linear slope of the inspiratory phase to monitor lung compliance. The measurements of the slope characterize a pressure wave index which is recorded at regular intervals to provide a clear record from which a warning of the patient's pulmonary condition such as lung compliance can be derived. Several techniques are shown and described. In one, the pressure wave index is determined by sensing the times when the pressure-time signal reaches predetermined pressure levels above a base line. In another technique, the linear slope segment is searched for and its slope then measured.
