This is when blood flow to your colon slows down or stops. The lack of oxygen causes damage to your intestine. The blockage can happen slowly over time, such as when cholesterol builds up in your arteries. Or it can happen all of a sudden from a blood clot or from a serious drop in...
Through experiments and simulations, the researchers examined the common assumption of disordered blood flow, and found that a healthy red blood cell is rather soft and flexible. When red blood cells are hardened in diseases such as sickle cell anemia, however, that order is suppressed. "Red blo...
the first point or advantage gained in a contest (比赛中)先得分,占先 King &B{drew first blood} when he took the opening set. 在网球开盘局中金抢先得分。 give blood allow blood to be removed medically from one's body in order to be stored for use in transfusions ...
This would potentially entail an increased gastrointestinal blood flow (GBF) in order to transport absorbed ions and increase oxygen supply as metabolic demands increase in the active gastrointestinal tissues16,17. Even so, despite the previously suggested benefits of gastrointestinal hyperemia during ...
Contemporary paradigm of peripheral and intracranial vascular hemodynamics considers physiologic blood flow to be laminar. Transition to turbulence is considered as a driving factor for numerous diseases such as atherosclerosis, stenosis and aneurysm. Re
It calculates blood flow rate from the device in order, to control the balloon pumpAn apparatus for a heart assist device, comprising a processing unit for computing the blood flow rate from the arterial pressure curve and for predicting at every heartbeat the closing time of the heart valve ...
Large roller clamp with closure ensures precise flow rate setting;Medical grade materials (safety tested):Injection port - medical grade plastic or metal; Drip chamber - medical grade PVC/ thermoplastic elastomers; Membrane filter - polypropylene; Tubing - medical ...
Moderate and severe arterial stenoses can produce highly disturbed flow regions with transitional and or turbulent flow characteristics. Neither laminar flow modeling nor standard two-equation models such as the k- turbulence ones are suitable for this kind of blood flow. In order to analyze the tr...
One-dimensional blood flow models have been used extensively for computing pressure and flow waveforms in the human arterial circulation. We propose an improved numerical implementation based on a graphics processing unit (GPU) for the acceleration of the execution time of one-dimensional model. A no...
Thermal enhancement and numerical solution of blood nanofluid flow through stenotic artery ArticleOpen access19 October 2022 Introduction In order to understand how hemodynamics factors effects the atherosclerotic disease FSI study is considered as powerful tool. FSI combines the wall stress with blood flo...
