EVLWI

[value of the normal] extravascular lung water indexed [to the body weight](English)

  • to preserve their function of oxygenation, the lungs must be kept dry. The volume of EVLW is strictly controlled by the lymphatic drainage system, which constantly removes EVLW from the interstitial tissue and pours it into the superior vena cava through the thoracic duct. In the normal lung, the value of the normal EVLW indexed to the body weight (EVLWI), which results from the equilibrium between fluid leakage and lymphatic drainage, is <7 mL/kg of body weight. Increased interstitial EVLW can occur as the result of increased pulmonary microvascular hydrostatic pressure or of decreased blood oncotic pressure or as the result of increased permeability of the alveolocapillary barrier, as typically in ARDS
