Is it time to measure lung water by ultrasound?

LUS for lung congestion diagnosis has low predictive power (low sensitivity andspecificity), with information that does not discriminate between differentconditions: it can beunreliable if not used jointly with thorough clinical assessment.The increase in lung‘‘weight’’ can be due to ‘‘interstitial congestion’’and not to lungconsolidation (atelectasis with pneumonitis,pleural effusion,hemorrhages, and other conditions). We still need more reliable noninvasive tools for assessinglung water content and its changes.
