Fig. 2From: Fluid responsiveness predicted by transcutaneous partial pressure of oxygen in patients with circulatory failure: a prospective studyChanges in transcutaneous partial pressure of oxygen before and during a PLR and then before and after volume expansion. PLR, passive leg raising. PtcO2, transcutaneous partial pressure of oxygen. *p < 0.05 versus before PLR, # p < 0.05 versus before volume expansionBack to article page
