When … WebSep 4, 2008 · To describe the magnitude of reactive hyperemia-induced shear stress elicited with increased duration of occlusion, shear stress AUC was calculated for each occlusion condition. Briefly, the AUC was calculated by summing the areas of successive postocclusion trapezoids (each with a base of 3-sec) for 60 sec (SS60sec AUC; a.u.).
WebReactive hyperemia results from oxygen starvation caused by an occluded blood vessel such as when you sit on your foot funny, and it falls asleep. Then you get up and it feels like someone is sticking a thousand pins in it. False. Reactive hyperemia is the increase in blood flow to a tissue or organ that occurs following a period of reduced ... WebReactive hyperemia was subsequently induced in the ipsilateral arm by inflation of a blood pressure cuff to greater than systolic arterial pressure for 3-5 min. This inflation was followed by rapid deflation of the cuff. ECG and pulsed Doppler tracings were obtained before cuff inflation and immediately after deflation.
