A more advanced approach using extravascular lung water provides a systematic route to therapeutic options. Extravascular lung water is indexed to the body weight in kg, written as the extravascular lung water index (ELWI). By indexing to the patient’s predicted body weight (PBW), underestimation of lung water, particularly in obese patients, is avoided.
