Methods Patients with severe acute lung injury or ARDS who were managed with inverse-ratio pressure control ventilation neuromuscular blockade and a pulmonary artery catheter were switched to APRV. Hemodynamic performance as well as pressor and sedative needs was assessed after discontinuing neuromuscular blockade Results Mean age was 58 9 years n 12 and mean Lung Injury Score was . Temperature and arterial oxygen tension fractional inspired oxygen FiO2 were similar among the patients. Peak airway pressures fell from 38 3 for PCV to 25 3 cmH2O for APRV and mean pressures fell from 18 3 for PCV to 1 2 2 cmH2O for APRV. Paralytic use and sedative use were significantly lower with APRV than with PCV. Pressor use decreased substantially with ARPV. Lactate levels remained normal but decreased on APRV. Cardiac index .
