In intensive care patients, due to increase in hydrostatic pressure and hyperpermeability state, pulmonary edema occurs. In this review, we discussed about definition and amount of extravascular lung water index (EVLWI) which relates to an increasing pulmonary capillary hydrostatic pressure or increasing capillary permeability. EVLWI-to-intrathoracic blood volume ratio is useful in determining the cause of pulmonary edema. EVLWI can be helpful in approximation of the amount of fluid overload and capillary leak in acute inflammatory injury. This is identified as a prognostic marker that is related to respiratory function and mortality in patients with acute respiratory distress syndrome and sepsis. Usage of EVLWI for determining of pulmonary edema in children would be beneficial.
