Dynamic pressure--flow velocity relationships in the human cerebral circulation.
BACKGROUND AND PURPOSE The pressure-flow velocity relationship in the cerebral circulation is characterized by the critical closing pressure (CCP), which is the pressure at which flow ceases, and the linear slope of a plot between pressure and flow velocity. It has been suggested, but not validated, that CCP can be determined from arterial blood pressure (ABP) and transcranial Doppler (TCD) rec...
متن کاملFlow Pattern Identification and Pressure Drop Calculation for Gas-Liquid Flow in a Horizontal Pipeline
Two phase gas-liquid flow pattern in a horizontal pipeline is predicted very accurately using a newly-developed analytical relation. The pattern identification is based on one of the most widely used graphs, the Baker diagram, modified in a way that compensates for the unrealistic oversimplifications of recent works. The Kern's method of pressure drop calculation is used to obtain the frict...
متن کاملInstantaneous pressure-flow velocity relations of systemic venous return in patients with univentricular circulation.
OBJECTIVE To assess the pressure and flow velocity relations and respiratory variability of the systemic venous and hepatic venous return in patients with univentricular circulation. PATIENTS 15 selected patients who had undergone cavopulmonary anastomosis (10) or atriopulmonary anastomosis (5). Mean age at operation was 55.1 months (range 9 to 145). Studies were done at 75.5 (32.6) months (m...
متن کاملCFD Simulation of Dry and Wet Pressure Drops and Flow Pattern in Catalytic Structured Packings
Type of packings and characteristics of their geometry can affect the flow behavior in the reactive distillation columns. KATAPAK SP is one the newest modular catalytic structured packings (MCSP) that has been used in the reactive distillation columns, recently. However, there is not any study on the hydrodynamics of this packing by using computational fluid dynamics. In the present work, a 3D ...
متن کاملRelationship between volume flow and velocity in the cerebral circulation.
The relationship between the velocity of the cerebral circulation and the cerebral blood flow was explored at varying levels of PaCO(2), systemic arterial pressure, intracranial pressure, and perfusion pressure, using radioisotope techniques in baboons. Only at low flow rates did velocity increase with flow, and then non-linearly; at high rates velocity increased progressively less. Changes in ...
