Reactive hyperemia increases forearm vein area.
PURPOSE To determine the effect of reactive hyperemia on human forearm vein area. METHODS After obtaining ethics approval and informed consent, an automatic tourniquet was applied to the forearms of 20 healthy subjects for one, two, and three minutes, at pressures of 25 mmHg, 200 mmHg, then 25 mmHg. A blinded radiographer measured the cross-sectional area of the cephalic vein at the wrist usi...
متن کاملReactive Hyperemia in Human Forearm Vessels
Background The role of nitric oxide (NO) in reactive hyperemia (RH) is not well known. We investigated whether NO plays a role in RH in human forearm vessels by examining the effects of N0-monomethyl-L-arginine (L-NMMA), a blocker of NO synthesis, on reactive hyperemic flow. Methods and Results Forearm blood flow (FBF) was measured by strain-gauge plethysmography with a venous occlusion techniq...
متن کاملCharacterization and reproducibility of forearm arterial flow during reactive hyperemia.
Peripheral arterial flow has been assessed for a variety of indications including characterization of endothelial function during reactive hyperemia. However, quantification of this blood flow as a surrogate remains an imperfect reflection of endothelial function. We sought to better characterize hyperemic reaction to (1) elucidate the influence of the endothelial function and (2) assess the re...
متن کاملConverting enzyme inhibitor improves forearm reactive hyperemia in essential hypertension.
Endothelial function is known to be impaired in essential hypertensive patients. In this study, we examined whether antihypertensive drugs improve forearm vasodilatory response to reactive hyperemia in 26 patients with essential hypertension (62 +/- 2 years) without diabetes mellitus, hyperlipidemia, coronary heart disease, or cerebrovascular disease. Antihypertensive drugs were never given or ...
متن کاملTime course of forearm arterial compliance changes during reactive hyperemia.
Ultrasonic studies have shown that arterial compliance increases after prolonged ischemia. The objective of the present study was to develop an alternative plethysmographic method to investigate compliance, exploring validity and clinical applicability. Forearm pulse volume (FPV) and blood pressure (BP) were used to establish the FPV-BP relationship. Forearm arterial compliance (FAC) was measur...
