Fig. 11From: Hemodynamic effects of enhanced external counterpulsation on cerebral arteries: a multiscale studyDetailed structures of the whole blood circulatory system. The voltage sources Pe in artery and vein units were used to simulate the pressure provided by the counterpulsation cuffs, which only exist in A8–A13 and V8–V13. Diodes in V8–V13 were used to simulate the lower limbs’ venous valveBack to article page
