“…Over time, however, the double indicator technique has been replaced by the transpulmonary single thermal indicator technique, because the latter is relatively noninvasive and easy to perform and has proved to be an accurate means of quantifying extravascular lung water as an index of lung water [14,15] . Moreover, its accuracy is comparable to that of the pulmonary artery thermodilution technique for measuring cardiac output and assessing volume preload parameters in patients with sepsis, acute lung injury, burn shock, coronary artery bypass graft, and liver transplantation, among others [16][17][18][19][20][21][22] .…”
