Abstract: Extravascular lung water（EVLW） is the amount of fluid accumulating in the spaces outside the pulmonary vessels，which is a parameter commonly monitored for evaluating the severity of pulmonary edema in ICU patients.EVLW achieves increasing attention for it can be applied to assess pulmonary pathophysiological conditions，pulmonary circulation as well as the outcome of critically ill patients.Therefore，correctly monitoring EVLW is of great significance in the diagnosis and treatment of critically ill patients.In order to improve healthcare providers' understanding of EVLW monitoring，we introduced some currently used methods for monitoring EVLW，focusing on comparing the monitoring principles，procedure of use，limitations and developments between them.
