[How to choose the duration of prone-position ventilation in patients with acute respiratory distress syndrome caused by pulmonary or extrapulmonary diseases?].
To determine the different effect of prone-position ventilation (PPV) in patients with acute respiratory distress syndrome (ARDS) resulting from a pulmonary cause (ARDSp) and that from an extrapulmonary cause (ARDSexp) on oxygenation, respiratory mechanics and hemodynamics. To determine an appropriate duration of ventilation in the prone position in the two groups. ⋯ PPV could be used to improve severe hypoxemia of ARDS. It improved the PaO(2)/FiO(2) ratio rapidly in ARDSexp, but in ARDSp the improvement took a longer time.
