WebExercise VO2 (1,278 +/- 122 ml/min) was normal relative to work load, but, contrary to that in normal subjects, QT was higher and PVR did not fall. During exercise, PaO2 showed a trend to decrease (to 90 +/- 5 mm Hg) and PaCO2 to rise (to 35 +/- 2 mm Hg), but the differences failed to reach statistical significance (p = 0.07 each). WebIn health, ScvO 2 is slightly lower than SvO 2 by about 2% to 3%, in part because of the high metabolic rate of the brain and cranial half of the body and also because of the contribution of vascular circuits that use blood for nonoxidative phosphorylation needs in the caudal half of the body (e.g., the renal blood flow). 84 In shock states the ... grabar pantalla windows 11 60 ftg

WebOn the basis of the high venous pressure, the behavioral trends between the PVA and venous pressure, the high PVO2, and the low %SaO2 and PVA in the dependent finger, we conclude that the PVA of the PEPG is determined mainly by venous pulse volume generated by shunting of arterial pulse via open arteriovenous (AV) anastomoses in the cutaneous ...
