A gas analysis apparatus, and a method for calibrating for compensating measurement errors, are disclosed. This method and apparatus are particularly suited for use during a cardiopulmonary exercise test by a test subject. The oxygen and carbon dioxide concentrations of the subject's breath are measured. Errors are compensated based on the results of previous calibration. The compensated measurements, as well as other physiological data monitored during the cardiopulmonary exercise test, and quantities calculated from these measurements, are presented as a series of graphs in a logical order to enhance their diagnostic, their prognostic value. A face mask (140), and head straps (144) are adapted for use with the gas analysis apparatus. The face mask (140) possesses a plurality of pins (142) fitting into corresponding holes (46) in the head straps (144), and the head straps (144) possess quick release attachment means to provide for quickly securing the face mask to or removing it from a subject.
