Abstract
Cardiac output by thoracic bioimpedance, heart rate, BP, oxygen saturation, and transcutaneous oxygen tension were measured at 1-min intervals in 45 patients before and after passive leg raising (PLR). Mean cardiac index increased only 0.09 ± 0.02 (SEM) L/min ċ m2 (p < .001), mean transcutaneous oxygen tension increased 1.6 ± 0.6 torr (p < .01), and mean oxygen saturation decreased 0.5 ± 0.2% (p < .01) after PLR. There were no significant changes in heart rate or systolic BP. Seven (16%) patients had increased cardiac index >10% after PLR.Keywords
