Instanteous Pressure Distribution along the Human Aorta.
• The ejection of blood into the root of the aorta by the heart produces pressure changes which are transmitted peripherally through the vascular bed. The propagation of these pressure waves has been a topic of interest and conjecture for a number of years because of its importance in the study of the physical properties and energetics of the vascular bed. As a result many data have accumulated...

متن کاملRegional wave travel and reflections along the human aorta: a study with six simultaneous micromanometric pressures.
The human aorta and its terminal branches were investigated in normal subjects during elective cardiac catheterization to evaluate regional wave travel and arterial wave reflections. A specially designed catheter with six micromanometers equally spaced at 10 cm intervals was positioned with the tip sensor in the distal external iliac artery and the proximal sensor in the aortic arch. Simultaneo...
متن کاملQuantification of wave reflection in the human aorta from pressure alone: a proof of principle.
Wave reflections affect the proximal aortic pressure and flow waves and play a role in systolic hypertension. A measure of wave reflection, receiving much attention, is the augmentation index (AI), the ratio of the secondary rise in pressure and pulse pressure. AI can be limiting, because it depends not only on the magnitude of wave reflection but also on wave shapes and timing of incident and ...
