Pulsatility indices was calculated for each of these vessels. A new placental pulsatility index was constructed as: (umbilical artery pulsatility index + mean of the left and right uterine artery pulsatility indices)/2, and mean +2 SD defined as abnormal.


An increasing number of laboratories are now offering colour flow-directed measurements such as pulsatility and resistance indices as well as flow velocities. 2,13,26,29,32,39,57,60 Some colour flow studies are still considered investigational in the USA. The pulsatility index is calculated by the following formula:

Along with the resistive index (RI), it is typically used to assess the resistance in a pulsatile vascular system. pressure and pulsatility index are less effective at quantifying pulsatility for mechanically derived flows, particularly with the growing trend of CVAD speed modulation to achieve various pulsatile flow patterns.

Uterine artery pulsatility index (UtA‐PI) (a) and angle of insonation (b) measured using transabdominal (TAS) and transvaginal (TVS) ultrasound in the first trimester of pregnancy (n = 97).Bars represent mean ± SD for UtA‐PI and median and interquartile range (IQR) for angle of insonation. One tool in the surgeon’s arsenal to detect a graft in trouble is Pulsatility Index that combines mean flow and waveform properties into one number. Introduced by D’Ancona and colleagues about 2000, the Pulsatility Index is simply calculated by subtracting the minimum recorded flow from the maximum recorded flow and dividing the difference by the mean flow. Vad pulsatility index keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on … artery pulsatility index (UtA-PI) at 12, 22, 32 and 36weeks’ gestation in singleton pregnancies which develop pre-eclampsia (PE) and examine the performance of this biomarker in screening for PE. Methods UtA-PI was measured in 92712 singleton preg-nancies at 11–13weeks, in 67605 cases at 19–24weeks, Although pulsatility is typically reduced with a higher LVAD speed, the concomitant increase in cardiac output may have significant effects beyond that of reduced pulsatility. Acutely, a larger flow into the cerebral circulation will result in increased resistance and possibly higher pressure.
