Abstract:Venous insufficiency is associated with decreases in muscle blood flow (MBF) and oxygenation of the leg. We hypothesize that mild external compression of the leg increases microvascular MBF and oxygenation in a leg experiencing venous hypertension. Thigh compression was used as a model for venous hypertension in five healthy subjects (3 males, 2 females). MBF was measured using photoplethysmography (PPG) and relative muscle oxygenation was measured using near‐infrared spectroscopy (NIRS). Both PPG and NIRS pro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
