[Assessment of fluid volume in critically ill patients with extravascular lung water index].
To examine the effect of rapid infusion test guided by extravascular lung water index ( EVLWI ) on hemodynamics in critically ill patients at different states in order to guide volume resuscitation. ⋯ Rapid fluid replacement in critically ill patients with crystalloid, regardless of whether the EVLWI was normal or increased, the short-term response was affected by the volume and cardiac function of patients. Different status of patients showed different volume effect curve: no significant changes in hemodynamic parameters were found in patients with normal EVLWI and volume parameters. In patients with potential cardiac dysfunction, CI and EVLWI increased significantly; regardless of PVPI increased or normal, EVLWI and CI were increased in patients with elevated EVLWI; two different changes could be found in the two types of pulmonary edema while ITBVI was increased.

[A prospective clinical study of pleth variability index in prediction of volume responsiveness in patients with septic shock].
To evaluate the role of pleth variability index ( PVI ) by passive leg raising ( PLR ) test in volume responsiveness and volume status prediction in patients with septic shock. ⋯ PVI and SVV can better predict fluid responsiveness in mechanically ventilating patients with septic shock after PLR. PVI as a new continuous, noninvasive and functional hemodynamic parameter has the same accuracy as SVV.
