A nonlinear mathematical model for pressure controlled, variable compliance ventilation is proposed, solved, and analyzed. The effect of the variable compliance on the key outcome variables, tidal volume, average lung volume, total PEEP, and mean alveolar pressure, is presented. Using human data, the variable compliance model is used to investigate effects of recruitment maneuvers on the key outcome variables.
