摘要: Porje I. G. and B. Rudewald. Hemodynamic studies with differential pressure technique. Acta physiol. scand. 1961. 51. 116–135. A theoretical analysis of the fluid motion in a circular elastic tube is presented. The formulae for computation pulsatile flow other hydro-dynamic data are discussed. Apparatus technique recording are, described. Results hydrodynamics model circulation system show that theory valid. For kinematic viscosities ranging from 1–9 cst main unaltered. Original records ascending aorta cases normal aortic valves presented their features Blood velocity curves computed such To illustrate use method effect Valsalva manoeuvre nitrite (Etrynit, Bofors) upon blood demonstrated.
