Table 2 Mode comparisons of intracycle total power areas (A, joules) and maximum intracycle power levels (M, watts) that are inscribed above a pressure threshold of 20 cmH2O for two severities of ARDS

From: Intracycle power and ventilation mode as potential contributors to ventilator-induced lung injury
