The Gosling pulsatility index (PI) was compared between baseline and ICP plateau waves (n = 20 patients) or short term (30-60 min) hypocapnia (n = 31). In addition, a modeling study was conducted with the "spectral" PI (calculated using fundamental harmonic of FV) resulting in a theoretical formula expressing the dependence of PI on balance of cerebrovascular impedances.

Home. About Dr. Zad. ductus venosus diameter and the pulsatility index in each fetus during fetal quiescence. Statistical Package for the Social Sciences 14.0 software was used to create nomograms for the ductus venosus pulsatility index and diameter against gestational age. Four hundred and sixty normal fetuses aged seventeenth to thirty-seventh weeks were evaluated. was used for calculation. It has been shown that a quality control process can improve the quality of mean uterine artery pulsatility index measurements [17]. Therefore, only well-trained operators who followed the above-established protocol performed the uterine artery measurements.

PI was calculated according to the method of Gosling [6]. Briefly, PI is calculated from the difference in the systolic and diastolic flow velocity divided by the mean 

This value decreases with distance from the heart. the lesion and for calculation of Resistive index (RI) and Pulsatility index (PI) Doppler ultrasound was performed .Operative findings were recorded. Post operative histopathological findings were considered as gold standard for characterization of benign or malignant ovarian masses.

Pulsatility index: Decreased index, may indicate low preload; Increased index, may indicate volume overload; Pump speed and pulsatility index are inversely related; Applications. Modern applications have expanded beyond original purpose: Bridge to cardiac transplant; Temporizing measure for cardiomyopathies that are expected to resolve

The only additional patient signal required is a simple three-lead e.c.g Correlation between intracranial pressure and pulsatility index measured by transcranial Doppler in children with severe trauma brain injury.
