From: The clinical usefulness of extravascular lung water and pulmonary vascular permeability index to diagnose and characterize pulmonary edema: a prospective multicenter study on the quantitative differential diagnostic definition for acute lung injury/acute respiratory distress syndrome

Figure 4

Extravascular lung water index and pulmonary vascular permeability index/intrathoracic blood volume correlation in ALI/ARDS patients. Correlation between extravascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI) and that between EVLWI and intrathoracic blood volume (ITBV) in patients with acute lung injury/acute respiratory distress syndrome. There was a strong correlation between EVLWI and PVPI (r = 0.729, P < 0.01) (A) and a weak correlation between EVLWI and ITBV (r = 0.236, p < 0.01) (B). EVLWI-0, extravascular lung water index on the day of enrollment; PVPI-0, pulmonary vascular permeability index on the day of enrollment; ITBV-0, intrathoracic blood volume on the day of enrollment.
