Blood Flow in the ArteriesThe arterial system is a many-branched elastic conduit for distribution of blood from the heart to all body tissues. Its calibre ranges from 4 cm for the human aorta to 4 μm for the capillaries. Over...
entirely new approach to the study of arterial haemodynamics, provides a theoretical basis to understanding blood flow in normal and disease conditions. It examines the relationship between pulsatile pressure and flow in the arteries using a mathematical model of fluid flow principles. The current ...
The interest in studying blood flow dynamics lies in the range of diseases in which malfunctions in the circulatory system are directly implicated. One of the major causes of abnormal circulation is the formation of atheroma. Among the factors contributing to atherosclerosis are haemodynamic factors ...
The application of LTA to the measurement of blood flow was demonstrated in rabbits and non-human primates [2,3,24]. A number of parameters relevant to hemodynamics were extracted from the progression of the dye front from the arteries, through the capillary bed and into the veins. Blood ...

➤Pressurized by air pump and air bag. Small pressure changes in the balloon caused by fluctuations in blood flow in the arteries below the balloon are processed by an internal pressure sensor to measure blood pressure. Also known as "oscillography" ...

Prenatal detection of congenital heart disease facilitates the opportunity for potentially life-saving care immediately after the baby is born. Echocardiography is routinely used for screening of morphological malformations, but functional measurements of blood flow are scarcely used in fetal echocardiography ...
This paper considers a finite element method to characterize blood flow in the human arm arteries. A set of different pressure waveforms, which represent normal and diseased heart pulses, is used for the proximal boundary conditions, and a modified Windkessel model is used for the distal arterial...
Background: It has been proposed that blood flow in coronary arteries is augmented by waves travelling-back from, the distal aorta. However, these waves ha... TER DaviesZI WhinnettN HadjiloizouJ Aguado-SierraKH ParkerDP FrancisAD HughesJ Mayet - 《Journal of Human Hypertension》 被引量: 0...
