Procedure to measure P0.1. Ventilator screen displaying P0.1 calculated from the change in airway pressure associated with 0.1 s of airway occlusion. Gray arrow indicates the buttons used for P0.1 measurement. Gray square indicates the intervals of 0.1 s of airway occlusion. White arrow indicates the negative airway pressure occurring during 0.1 s of airway occlusion (P0.1), with the most recent data being − 1.5 cm H2O
