Effect of Fluid Balance on Alveolar-Arterial Oxygen Gradient in Mechanically Ventilated Patients

摘要

BackgroundFluid balance affects outcome in critically ill patients. We studied the effect of fluid balance on oxygen exchange by assessing alveolar-arterial oxygen gradient (PA-a O2) in mechanically ventilated patients. Our primary objective was to evaluate the difference in PA-aO2 and the secondary goal was to evaluate the differences in age and mortality rate.
