Abstract

Background: Increased extra-vascular lung water (EVLW) is common in critical care and correlates with the severity of acute lung injury, length of intensive care unit stay and mortality. Lung ultrasound (LUS) can assess EVLW by determining the amount of ‘B-lines’: artefacts signifying alveolar-interstitial oedema. This study’s aim was to determine whether EVLW estimation with the help of LUS correlates with the more accurate PiCCO₂^® cardiac output system utilising transpulmonary thermodilution.
