and colleagues [1] investigated the correlation between extravascular lung water (EVLW) and Normal range estimation for repeated immunologic measures.

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). 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). Extravascular lung water (EVLW) measurement may improve outcome.

TPTD monitors also incorporate a pulse-contour technology which allows the measurement of continuous CO and of ﬂuid-responsiveness indicators such as the pulse pressure and the stroke volume variations (PPV and SVV), which are 2020-05-24 The measurement of EVLW may be altered by systematic or accidental errors of measurement. The single-indicator method relies on a predictable and constant relationship between the GEDV and the ITBV. Underperfusion that occurs pulmonary resection, pulmonary embolism, and pulmonary arterial occlusion may underestimate EVLW by about 10% [ 55 , 56 ]. EVLW measurements by TPTD and TPDD were performed at vari-ous levels of lung water and the ﬁnal EVLW values were compared . with the post mortem gravimetry results. Data were analyzed .

EVLW measurements were made at baseline, 30 min (after lung injury and hemorrhage), and 120 min. The animals were then volume-resuscitated over a period of 60 min, and a final EVLW measurement was made at 180 min. Linear regression was used to determine an accurate estimate of ITBV obtained through fixed transformation of GEDV.

may aﬀect the measurement of EVLW by dilution methods as well as the actual amount of EVLW [39]. Increasing PEEP may reduce pulmonary vascular ﬂow reducing the measured EVLW [39]. Increasing PEEP may also increase pulmonary ﬂow to previously excluded areas, increasing the measured EVLW [40, 41]. Increasing PEEP may increase

The chest radiograph (CXR) can potentially estimate the quantity of lung For a more direct assessment, a tight correlation between. B-lines and EVLW was confirmed by measuring the wet-to-dry ratio of postmortem lung tissue in a pig. and extravascular lung water measured by transcardiopulmonary thermodilution: as the EVLW divided by the predicted body weight.15 EVLWI measured by outside of the pulmonary vasculature. The abnormal accumulation of EVLW is a frequent.

EVLW measurements were made at baseline, 30 min (after lung injury and hemorrhage), and 120 min.

Thermodilution measurement of EVLW values showed high accuracy in normal lungs, cardiogenic pulmonary edema, and ARDS models. In a human autopsy study, we observed a definite correlation between EVLW and postmortem lung weight from a wide range of normal and injured lungs. Currently, EVLW and pulmonary vascular permeability index (PVPI) can be quantitatively measured using the transpulmonary thermodilution (TPTD) technique.

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).

Studies using transthoracic thermodilution have demonstrated increased extravascular lung water (EVLW) measurements attributed to progression of edema

Increasing PEEP may reduce pulmonary vascular ﬂow reducing the measured EVLW [39]. Increasing PEEP may also increase pulmonary ﬂow to previously excluded areas, increasing the measured EVLW [40, 41]. Increasing PEEP may increase In ARDS patients, EVLW was shown to correlate well with quantitative computed tomography22. Further ‘face’ and ‘construct’ validity of EVLW measurement in a clinical setting has been demonstrated by numerous studies observing association between EVLW and clinical findings suggestive of increased lung water such as: oxygenation16, 23-26, In this report, we evaluated and discussed the accuracy and the clinical problems involved in measurements of extravascular lung water volume (EVLW), using the thermal-sodium double indicator dilution technique.
