Abstract

Parametric characterization of nitric oxide (NO) gas exchange using a two-compartment model of the lungs is a non-invasive technique to characterize inflammatory lung diseases. The technique applies the two-compartment model to parametric characterization of NO gas exchange from a tidal breathing pattern. The model is used to estimate up to six flow-independent parameters, and to study alternate breathing patterns.
