Influence of extravascular lung water on transpulmonary thermodilution-derived cardiac output measurement.
The transpulmonary thermo-dye dilution technique enables assessment of cardiac index (CI) intrathoracic blood volume index (ITBVI) and extravascular lung water index (EVLWI). Since the extent of lung edema may influence the reliability of CI measurement by transpulmonary thermodilution due to loss of indicator, we analyzed the impact of EVLWI on transpulmonary thermodilution-derived CI in critically ill patients. ⋯ Measurement of cardiac output by transpulmonary thermodilution is not influenced by EVLWI in critically ill patients and loss of indicator as the underlying reason is probably overestimated.

Respiratory system inertance corresponds to extravascular lung water in surfactant-deficient piglets.
In various cardio-pulmonary diseases lung mass is considerably increased due to intrapulmonary fluid accumulation, i.e. extravascular lung water (EVLW). Generally, inertance is a physical system parameter that is mass-dependent. We hypothesized that changes in lung mass influence the inertive behavior of the respiratory system. ⋯ I(rs) increased by 35% (from 0.17+/-0.02 to 0.23+/-0.04 cmH(2)O s(2)/L (p = 0.036) after BAL) and was tightly correlated to EVLW (r(2) = 0.95, p < 0.023). ITBV did not change significantly after BAL. We conclude that I(rs) reflects actual changes in lung mass and thus hints at fluid accumulation within the lung.

[Clinical investigation of extravascular lung water index and pulmonary vascular permeability index in diagnosis and continuous monitoring of lung edema].
To study the clinical value of extravascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI) in the diagnosis and continuous monitoring of lung edema. ⋯ EVLWI and PVPI monitoring is of clinical value to some degree in early diagnosis of hydrostatic pulmonary edema and permeability pulmonary edema.

Extravascular lung water in sepsis-associated acute respiratory distress syndrome: indexing with predicted body weight improves correlation with severity of illness and survival.
To determine whether extravascular lung water predicts survival in patients with early acute respiratory distress syndrome, to determine the relationship between extravascular lung water and other markers of lung injury, and to examine if indexing extravascular lung water with predicted body weight (EVLWp) strengthens its discriminative power. ⋯ Increased extravascular lung water is a feature of early acute respiratory distress syndrome and predicts survival. Indexing extravascular lung water to predicted body weight, instead of actual body weight, improves the predictive value of extravascular lung water for survival and correlation with markers of disease severity.
