Flow pulsatility
WebA low-flow, high-pulsatility waveform with a low-flow trough was seen on the HVAD monitor suggestive of relative hypertension. Systolic pressure by Doppler was 110 mm … WebAug 1, 1997 · Marked pulsatility of venous flow (VPI > 0.5) was found in 12 of 23 subjects. We found an inverse correlation between the VPI and the subjects' body mass index (r = -.76; p < .001).

WebIn fetal sheep with intrauterine growth retardation (IUGR) caused by placental insufficiency, fetal blood flow is redistributed. 1 Blood flow to heart, brain, and adrenals is increased in compensation, while other organs including the gastrointestinal tract are relatively hypoperfused. 2 Fetal blood flow pulsatility shows this effect by changes in flow … WebJun 1, 2011 · CONCLUSIONS: Arterial flow patterns showed a significant reduction in PI, RI, and PA when compared distal to proximal to the carotid siphon. The observed attenuation of flow pulsatility is most likely related to the contorted shape of the distal ICA and may bear a protective effect for downstream cerebral vasculature.
WebThe data was analyzed with the help of SPSS version 25.0. Variables like age, gender, diabetes, and Intima-media thickness (IMT) were reported and the mean ± standard deviation of Pulsatility Index, Resistive Index, Peak Systolic Velocity, and End Diastolic Velocity were calculated with a significant p-value, which is less than 0.05.
