Effect of Pentoxifylline on Microvascular Blood Flow Velocity
Angiology, 1981Pentoxifylline (PF), known to increase red blood cell (RBC) deformability, has recently attracted much attention because of its possible effect of reducing capillary resistance. There has been practically no reliable demonstration of an increase in capillary blood flow by this drug.

Retinal blood flow velocity in metabolic syndrome
Graefe's Archive for Clinical and Experimental Ophthalmology, 2013Metabolic syndrome (MetS) is characterized by obesity, insulin resistance, dyslipidemia, and hypertension. The Retinal Function Imager (RFI) is a new technique for measuring retinal blood-flow velocity. This study aims to compare retinal blood flow velocity between MetS and healthy subjects.Twenty eyes of 20 MetS males and 21 eyes of 21 aged-matched ...

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.

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 ...

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 ...

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 ...

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
