Abstract

Analytical expressions are derived for the work of breathing (WOB) and are subsequently evaluated for a typical pulmonary function laboratory test that includes tidal breathing, panting and the forced vital capacity maneuvers. The analysis is based on a nonlinear model of respiratory mechanics that successfully mimics information presented in the conventional Campbell diagram, which is often used to graphically estimate WOB. In addition, the model reveals the partitioning of elastic WOB among the collapsible air-ways and lung.
