[ We claim:] [1.] A method of determining a leak component of gas flow in a respiratory gas supply system for supplying respiratory gas to a patient, comprising the steps of:determining a beginning and an end of a plurality of patient breaths, each breath comprised of an inspiratory phase and an expiratory phase;integrating patient respiratory gas flow rate throughout said plurality of patient breaths to determine a total respiratory gas volume for said plurality of patient breaths; anddividing said total respiratory gas volume for said plurality of patient breaths by a time duration of said plurality of patient breaths to determine a leakage rate for said plurality of patient breaths.
