Measurements of Blood Flow Velocity in the Microcirculation [PDF]
Upsala Journal of Medical Sciences, 1975 A method for the measurement of red blood cell velocity in the microcirculation is described. The technique is based on the on-line cross-correlation of the delay between optical signatures derived from photodetectors aligned in direction oflow. A specialised photodiode holder which can be inserted directly in place of an ocular is described.

Excess pressure as an analogue of blood flow velocity
Journal of Hypertension, 2020 Introduction: Derivation of blood flow velocity from a blood pressure waveform is a novel technique, which could have potential clinical importance. Excess pressure, calculated from the blood pressure waveform via the reservoir-excess pressure model, is purported to be an analogue of blood flow velocity but this has never been ...

Transcutaneous measurement of blood velocity profiles and flow [PDF]
Cardiovascular Research, 1973 A comprehensive report is presented of the application of a pulsed ultrasound Doppler velocity meter for transcutaneous measurement of time varying velocity, velocity profiles, and instantaneous flow in arteries of anaesthetized dogs. The procedure used to provide direct velocity and flow calibration using the Doppler equation is outlined.

[Cerebral blood flow in infants: comparison of carotid blood flow and cerebral blood velocity].
No to hattatsu = Brain and development, 1990 Carotid blood was measured with a ultrasonic volume flow meter in 38 infants. The carotid blood flow was 1.50 +/- 0.55 ml/sec. At the same time peak systolic flow velocity, mean blood velocity, end diastolic velocity, pulsatility index (PI) and resistance index (RI) in the middle and anterior cerebral arteries were measured by duplex Doppler scanning ...

Blood Flow Velocity in a Patient with Takayasu's Arteritis
Japanese Heart Journal, 1972 Blood flow velocity was recorded by using Doppler transcutaneous flowmeter and Doppler catheter flowmeter in an 18-year-old woman with Takayasu's arteritis. Although no right radial artery pulse was felt by palpation, significant decrease and slow rise of the peak blood flow velocity, and inconspicuous dicrotic notch was observed and recorded from the ...

Daily rhythm of cerebral blood flow velocity
Journal of Circadian Rhythms, 2005 BACKGROUND: CBFV (cerebral blood flow velocity) is lower in the morning than in the afternoon and evening. Two hypotheses have been proposed to explain the time of day changes in CBFV: 1) CBFV changes are due to sleep-associated processes or 2) time of day changes in CBFV are due to an endogenous circadian rhythm independent of sleep.

[Analysis of renal blood flow velocity in hydronephrosis].
Nihon Jinzo Gakkai shi, 1997 We investigated the velocity of renal blood flow on hydronephrosis using the pulse color Doppler ultrasound technique, comparing velocity on the healthy side with the diseased side of the renal, segmental and interlobar arteries. The velocities of the diseased side were markedly decreased, depending on the degree of hydronephrosis.
