The relation between PAOP, ELWI and PVPI. (a) The relationship between pulmonary artery occlusion pressure (PAOP) and extravascular lung water index (ELWI) in patients with sepsis and patients with acute heart failure. (b) The relationship between PAOP and pulmonary vascular permeability index (PVPI) in patients with sepsis and patients with acute heart failure. No significant correlation exists between PAOP and the other two variables in either group of patients. Dashed lines indicate PAOP of 18 mm Hg, ELWI of 10 mL/kg, and PVPI of 3.0.
