title: [Mathematical approach to the study of the capnographic curve].
abstract: An application of Hill's formula in the interpretation of slope of second phase of capnographic curve is suggested. This method can be used to demonstrate an acute rising of airway resistances, but failed to discriminate between normal and chronically broncho-pulmonary obstructed subjects. We suggest that a study of modifications of second phase slope and Q angle can give more information about airway resistances.
