Hemodynamics ! lower mean arterial pressure lower cardiac index Lung function better injury score better oxygenation index lower plateau pressure lower PEEP
Fluid management in ALI. NEJM, 2006, 354, 2564 Hemodynamics lower mean arterial pressure lower cardiac index Lung function better injury score better oxygenation index lower plateau pressure lower PEEP Metabolic function higher oncotic pressure, Hgb, albumine levels higher creatinine values metabolic alkalosis (hypoCl - ) electrolyte imbalance (hypoK +, hyperNa + )
Fluid management in ALI. NEJM, 2006, 354, 2564 Conservative strategy Improves lung function Shortens duration of MV Shortens ICU LOS
