Beurteilung des Flüssigkeitsgehaltes der Lunge anhand des Thorax-Röntgenbildes: Vergleich der Messung des extravaskulären Lungenwassers und der Ergebnisse radiologischer Beurteilungsmethoden*

Extravascular lung water (EVLW) was determined with the thermal-dye double-indicator method (119 individual measurements) in 23 patients in an intensive-care unit, and the results were compared with estimates made from largely standardized portable chest X-ray films, using the staging method of Sibbald as well as that of Halperin. There was a significant correlation with the measured EVLW for both methods. Radiologically "normal" films corresponded to a mean EVLW value of 8.4 ml/kg body-weight. Radiologically judged adjacent stages did not in all cases compare with corresponding measured EVLW values. But when EVLW values were clearly abnormal, the X-ray films always demonstrated massive int…
