[Evaluation of airway resistance determined by whole-body plethysmography].

V K Kuznetsova, Г. А. Любимов

Abstract

Methods of estimation of the airway resistance by flow-pressure curve obtained in whole-body plethysmography are investigated. The analysis of the physical processes controlling the flow-limitation during expiration shows that these methods are useful only for healthy subjects for the estimation of the airway resistance. The way for estimation of the airway resistance by flow-pressure curve is proposed.
