OBJECTIVE (1) Can one measure coronary collateral flow around an open critical stenosis? (2) Does intracoronary platelet thrombosis affect native coronary collateral vessels? METHODS We measured regional myocardial blood flow by the radioactive microsphere technique in seven anaesthetised dogs with an ultrasonic flowmeter on the circumflex branch of the left coronary artery (LCx). Measurement...
Bu~~AG, RUBEN D. Validation in awake rats of a tail-cuf method for measuring systolic pressure. J. Appl. Physiol. 34(2) : 279-282. 1973. -To determine why results of recent studies on applicability of the tail-cuff method to awake rats have been conflicting, arterial pressures were measured under various conditions. A Doppler ultrasonic flowmeter was used to detect blood flow changes occurring ...
This paper describes a process of numerical testing and optimization the ultrasonic gas meter channel. A conventional flowmeter requires large installation space due to quality stability velocity profile. Previously, shape inner channel was optimized reach suitable flow field for measurement. The goal this work is find an optimal design reduced size achieve stable profile with minimum disturban...
