EV1000/VolumeView: a new device for a more reliable measurement of extravascular lung water index in patients with lung resections

Hemodynamic monitoring is important in high-risk surgical patients in order to detect and correct circulatory instability, thereby improving outcome [1]. The extravascular lung water index (EVLWI) reflects pulmonary edema [2]. The new EV1000/VolumeView (Edwards Lifesciences) can accurately measure EVLWI corrected for the actual volume of lung parenchyma (EVLWIc). The aim of our study is to prove a stronger correlation between EVLWIc and PaO2/FiO2 compared with EVLWI in patients undergoing pulmonary resection.
