For inter-individual comparison, absolute values for ITBV and EVLW were normalized as indexed by body surface area (ITBVI, normal range: 850-1000 ml/m2) and Diagnostic Test: Lung ultrasound and EVLW measurement by transpulmonary thermodilution. Lung ultrasonography by 8 Quadrant protocol of Volpicelli et al. Transpulmonary thermodilution for extravascular lung water measurement Abstract. ABSTRACT: The availability of measurement of extravascular lung water (EVLW) were clinically evaluated by using double indicator dilution technique and benefit from EVLW measurement was assessed in patients who underwent pulmonary resection. EVLW can be estimated by pulse indexed contour cardiac output (PICCO) in combination with thermodilution or similar methods, 4,5 and left ventricular filling pressure is assessed during pulmonary arterial catheterization (PAC) by measuring the pulmonary capillary wedge pressure (PCWP). Normally EVLW is < 500 ml [ 4, 5, 6, 7 ]. With alveolar flooding, lung water content is usually > 75-100% above normal [ 8 ].

Our clinical–pathological study showed mean EVLW values of approximately 7.3 ± 2.8 ml/kg to be the normal reference range for humans ( n = 534) . Our results suggest that the important coefficient of variation of the EVLW-measurements is overall due to the variability of the difference between the 2 transit times measured. The temperature exchange between the intravascular cold bolus and the extravascular thermal volume is flow dependent especially at high EVLW-values.

In this study, we analyzed the prognostic value of EVLW in critically ill patients. 2009-07-06 2015-03-16 EVLW measurements were made at baseline, 30 min (after lung injury and hemorrhage), and 120 min.

and this may have affected the postmortem readings. We consider this to be p otentially the most serious lim-itation of our study. The 'normal' value for EVLW is reported to be 5–7 mL/kg with values as high as 30 mL/kg during severe pulmonary edema. In an intriguing study, Sakka et al. found that the mortality was
In order to use the TDD to determine the amount of extravascular lung water (EVLW), a fiberoptic catheter was placed in the femoral artery. Measurements and main results Fourteen consecutive ARF patients receiving mechanical ventilation were measured by EIT and TDD.
The original double-indicator dilution measurement of EVLW used a central injection of iced indocyanine green dye and exploited differences in the intrathoracic volume of distribution of the green dye, which remained primarily intravascular, and the thermal signal, which was diffusible into the lung mass.26Subsequent development and commercialization of a simpler technique using only iced saline, termed transpulmonary thermodilution , has made noninvasive assessment of lung water available

Assessment of EVLW after an intravenous central injection of iced saline involves considerable and at times conflicting assumptions.17,18The measurement premises include that the thermal indicator reaches and equilibrates equally in all lung regions and that the central circulation volumes between the injection and temperature measurement site can be described as a small number of individual However, current radiological, pressure, and oxygenation methods for measuring EVLW are unreliable in practice and cannot quantify EVLW.

The The main findings of this study are that (a) measurement of EVLW using the PiCCO single transpulmonary measurement system is very closely correlated to postmortem lung weight measurement and (b) an EVLW p of approximately 7.4 ± 3.3 mL/kg (males 7.5 ± 3.3; females 7.3 ± 3.3) is the reference value for normal lungs. The validation of EVLW measurements by thermodilution was based on studies showing reasonable correlations with gravimetry or thermo‑dye dilution in experimental and clinical stud‑ ies. EVLW should be indexed to predicted body weight. This indexation reduces the proportion of ARDS patients for whom EVLW is in the normal range. EVLW measurements were obtained by central venous injection of a 10 ml bolus of 0.9% saline <10°C. The mean value of three consecutive measurements was used for analysis. For inter-individual comparison, absolute values for ITBV and EVLW were normalized as indexed by body surface area (ITBVI, normal range: 850-1000 ml/m2) and Diagnostic Test: Lung ultrasound and EVLW measurement by transpulmonary thermodilution.
Introduction. Extravascular lung water (EVLW) remains a useful guide for monitoring pulmonary oedema (PO) and vascular permeability in sepsis, acute respiratory distress syndrome (ARDS), and heart failure (Jozwiak et al. 2015; Michard 2018). EVLW, measured by single indicator dilution, is a reliable measure of pulmonary edema that has been validated against postmortem gravimetric measurement in animals , computer tomographic lung density measurements and double dye dilution , and, recently in a human autopsy study . Measurement of extravascular lung water (EVLW) may be useful in the treatment of critically ill children and can be performed at the bedside using the transpulmonary thermodilution technique (TPTD).
