Normally EVLW is < 500 ml [ 4, 5, 6, 7 ]. With alveolar flooding, lung water content is usually > 75-100% above normal [ 8 ]. It is at this point that physiologic impairment usually occurs. Thus, any method that would be clinically useful must be able to detect changes in EVLW below the threshold of alveolar edema.

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

A linear regression equation was calculated: EVLW (mL) = 0.56 × lung weight (g) - 58.0. The normal EVLW values indexed by predicted body weight were approximately 7.4 ± 3.3 mL/kg (7.5 ± 3.3 mL/kg for males and 7.3 ± 3.3 mL/kg for females). Several studies suggest that a normal EVLW value should be approximately 7 ml/kg and should not exceed 10 ml/kg (indexed by predicted body weight). 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) [10]. 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. 2015-11-06 · How to measure EVLW?

Evlw measurement

The median EVLW value after three bolus injections of 15 mL each was analyzed for each measurement. The absolute EVLW value was indexed to actual body weight (EVLW a) and predicted body weight (EVLW p), which was calculated as 50 + 0.91 (height in centimeters - However, EVLW-values obtained by the thermal dye technique showed considerable overlap between cases of radiographic low grade pulmonary edema and we were able to identify several reasons for radiographic over- or underestimation of EVLW. in these patients EVLW-measurement by the thermal dye technique provides additional information, thereby probably influencing further treatment. (EVLW), as well as additional parameters of myocardial performance and pulmonary vascular permeability [7].

EVLW measurement can be affected by renal replacement therapy, extracorporeal membrane oxygenation (ECMO), pleural effusions and high PEEP.

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.

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 estimation of EVLW. EVLW measurement in critically ill patients EVLW or EVLW indexed to body weight is an impo rtant measure of the state of the lungs in critically ill patients as a high level is independently associated with a worse clinical outcome, including duration of mechanical venti-lation, ICU stay and mortality, whether associated with EVLW measurement despite strong competi-tion from non-invasive methods, including lung ultrasound, bioimpedance tomography and computed tomography (Michard 2018; Anile et al. 2017; Patroniti et al.

2005). Importantly, EVLW can serve as a guide for personalisation of haemodynamic manage-ment. Thus, critical illness resulting in shock Abstract Objective: 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). There are currently no data to verify the accuracy of these measurements in (small) children.
