From: Intracycle power and ventilation mode as potential contributors to ventilator-induced lung injury
Alveolar volume (L) versus time (s) for three flow profiles applied to lungs with same tidal volume, inspiratory time, and mechanical properties for R and C (PEEP = 0 cmH2O). Mathematically predicted (solid line) and physically observed (dotted line) quantities agreed particularly closely for the inflation phase of the flow-controlled modes (constant [CF] and decelerating [DF]). Inflation by the mechanical simulator lagged slightly in response to Pset inflation, due to the ventilator’s ‘ramped’ early pressurization algorithm
