Time constant-related capnograph distortion: a theoretical analysis.

Department of Anaesthesia, Toronto General Hospital, Canada.

Abstract

A theoretical analysis of time constant-related distortion in side-stream capnographs was carried out using two models of respiratory patterns. It is demonstrated that under circumstances likely to be encountered clinically, significant distortion may occur. This distortion may produce both spurious rebreathing and under estimation of the true end-tidal CO2 concentration.
