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 کاملA model of blood flow in the mesenteric arterial system
BACKGROUND There are some early clinical indicators of cardiac ischemia, most notably a change in a person's electrocardiogram. Less well understood, but potentially just as dangerous, is ischemia that develops in the gastrointestinal system. Such ischemia is difficult to diagnose without angiography (an invasive and time-consuming procedure) mainly due to the highly unspecific nature of the di...
متن کاملCoronary blood flow measurements in the presence of arterial obstruction.
As an approach to delivery of inert gas to the myocardium in the presence of coronary artery obstruction, Kr in saline was injected into a catheter in the coronary venous system of intact anesthetized dogs. Isotope delivered at the level of the great cardiac vein was selectively localized in the region of myocardium subserved by the vein and the left anterior descending artery. Similarly, injec...

15 صفحه اولBlood flow, not hypoxia, determines intramucosal PCO2
Monitoring tissue hypoxia in critically ill patients is a challenging task. Tissue PCO2 has long been proposed as a marker of tissue hypoxia, although there is considerable controversy on whether the rise in CO2 with hypoxia is caused by anaerobic metabolism and excess CO2 production or by the accumulation of aerobically produced CO2 in the setting of blood flow stagnation. The prevention of in...
