Mathematical model of the pressure–volume (PV) curve. PV curves obtained with a mathematical model simulating a multicompartmental lung model. The continuous PV curve reflects elastic properties of a completely recruited lung. The other curves represent the behavior of the simulated models according to a different mean opening pressure (10 cmH2O, 15 cmH2O and 20 cmH2O). Modified from [17]. Pel, elastic pressure; mPcrit = 10, mean opening pressure of 10 cmH2O; sdPcrit = 4 cmH2O, standard deviation of mPcrit.
