VELOCITY OF BLOOD FLOW IN SCHIZOPHRENIA
Archives of Neurology And Psychiatry, 1938Our purpose in this study was to determine the rate of blood flow in patients with schizophrenia. The work of Blumgart 1 has stimulated interest in studies on the velocity of blood flow. The circulation time, while it does not directly determine the velocity of blood flow, is the denominator in the equation distance of pathway/circulation time equals ...

Cerebral blood flow velocity in preterm neonates
Brain and Development, 1985The postnatal changes of cerebral blood flow velocity in 35 preterm neonates with or without complications were measured with a bidirectional Doppler flow meter. In the cases without complications, the pulsatility index for the anterior cerebral artery (ACA-PI) was high shortly after birth, and gradually decreased after 6 hrs as that in normal term ...

Blood flow and blood velocity measurement in vivo by electromagnetic induction
Transactions of the Institute of Measurement and Control, 1982The application of electromagnetic induction to the measurement of blood flow and blood velocity in vivo is reviewed, The electronic requirements are discussed and the associated problems are surveyed. A brief account is given of Bevir's virtual current theory and its application to flow and velocity measuring devices.

The Effect of Remifentanil on Cerebral Blood Flow Velocity
Anesthesia & Analgesia, 1998In the present study, we investigated the effect of remifentanil on cerebral blood flow velocity (CBFV). We investigated 20 patients (ASA physical status III) scheduled for elective coronary artery bypass graft surgery. Anesthesia was induced with remifentanil 5 microg/kg IV (Group 1, n = 10) or 2 microg/kg IV (Group 2, n = 10) and was maintained with ...

Effects of aging on cardiac blood flow velocities
Journal of Clinical Ultrasound, 1988AbstractThe effects of aging on cardiac blood flow velocities are important as a description of the natural history of the aging process and as a reference for evaluation of the aging cardiovascular system. We therefore studied these effects in 215 healthy volunteers, 120 males and 95 females, between 1 and 65 years old.

Astaxanthin increases choroidal blood flow velocity
Graefe's Archive for Clinical and Experimental Ophthalmology, 2011Previous studies have reported that astaxanthin (AXT) has antioxidative and anti-inflammatory effects in addition to its ability to shorten blood transit times. As laser speckle flowgraphy (LSFG) can noninvasively visualize the hemodynamics of the choroidal circulation, we used the technique to evaluate whether continuous ingestion of 12 mg of AXT per ...

Portal Blood Velocity and Flow in Aging Man
Gerontology, 2009The portal blood velocity and flow were measured by means of pulsed echo-Doppler in 60 normal subjects of 4 different age groups (≤ 40, 41–55, 56–70, ≥ 71 years). All subjects had normal routine liver function tests and no history of liver disease. Portal blood velocity decreased from 15.7 ± 3.2 cm/s in younger subjects to 12.4 ± 1.7 in subjects over ...

Effect of compression stockings on venous blood velocity and blood flow
Thrombosis and Haemostasis, 2010SummaryThe effects of graduated compression stockings (GCS) on venous blood velocity have not been established. In healthy subjects, most investigations showed no effect on blood velocity, but mixed results have been reported. In this investigation we to test the hypothesis that popliteal blood velocity is increased by properly fitted GCS. Time average

Real time blood flow velocity monitoring in the microcirculation
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005A real-time monitoring system based on the dual slit methodology for the characterization of the red blood cell velocity at the level of microcirculation has been developed. The analog photometric signals are acquired and processed using a hybrid hardware-software system that exploits a A/D conversion and an optimized correlation algorithm on an ...
