Venous flow velocity, venous volume and arterial blood flow.
The relationship of arterial blood flow and venous volume to venous flow velocity was studied in normal subjects. The effects of current modes of treatment in venous thrombosis and of a vasodilator drug on venous flow velocity were also investigated. Total calf flow and venous volume were measured by venous occlusion plethysmography while venous flow axial velocity was determined by the transit...
متن کاملPresentation of a Non-invasive Method of Estimating Arterial Stiffness by Modeling Blood Flow and Arterial Wall Based on the Determination of Elastic Module of Arterial Wall
Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
متن کاملArterial Blood Flow Blockage Time Due to an Interaction between a Foreign Second Phase and an Externally Originated Particle
A huge number of deaths in the world are the direct or indirect consequence of a disease which is called atherosclerosis. The disease could be due to an artery blockage by the interaction of an externally second phase with a particle which is entered to the bloodstream. The effect of some most important physical and geometrical affecting parameters on the blockage time of a microchannel due to ...
متن کاملValidity of cerebral arterial blood flow calculations from velocity measurements.
It is obvious that a noninvasive technique that can provide continuous measurements of blood flow through a cerebral artery would be very valuable for clinical and investigative purposes. The most promising approach to the development of such a technique involves the use of ultrasound for the measurement of blood flow velocity. Since blood flow through a vessel is equal to the instantaneous ave...
متن کاملHot-film anemometer velocity measurements of arterial blood flow horses.
Blood velocity measurements were carried out using a constant-temperature hot-film anemometer system in both anesthetized and conscious horses. Catheter probes were used to measure velocity wave forms in conscious horses and L-shaped needle probes inserted by direct vessel puncture were used to measure the profiles in regions of the thoracic and abdominal aorta of anesthetized, open-chest horse...
