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.

One parameter to quantify this difference is the pulsatility index (PI), which is equal to the difference between the peak systolic velocity and the minimum diastolic velocity divided by the mean velocity during the cardiac cycle. This value decreases with distance from the heart.

The RLI often is used to measure how long a well or mine will last, such as for oil, natural gas or minerals. Typically, the higher the RLI, the higher t Here's how to calculate your summer heat index from the current air temperature and humidity. You can do it by hand if you want. nd3000 / Getty Images We often check the high temperature forecast to see how hot the day will be. But that fig An index is a statistical measure or indicator.

The predictability of uterine artery mean pulsatility index (PI) at 11–14 weeks for hypertensive disorders of pregnancy was significantly high with an odds ratio of 174.45 (95% CI 65.31–549.13; p < 0.0001), sensitivity (89.3%), specificity (95.8%), positive predictive value(90.5%) and negative predictive value (95.1%). Conclusion An increased value of the resistive index (RI = [peak systolic velocity - end diastolic velocity]/peak systolic velocity) or the pulsatility index (PI = [peak systolic velocity - end diastolic velocity]/time averaged velocity) measured at the level of the interlobar arteries is associated with increased severity and duration of hypertension [11, 12].

We defined a novel hemodynamic index, the pulmonary artery pulsatility index (PAPi), and explored whether the PAPi correlates with severe RVD in acute IWMI. Methods: From 2008 to 2010, we identified 20 patients presenting with angiographically confirmed proximal right coronary artery occlusion and suspected RVD (sRVD) as defined by hemodynamic In the overall results there was a significant correlation (p < 0.0001) between the ICP and the PI with a correlation coefficient of 0.938 ().When separating severely elevated (>120 cm/s) and subnormal (<50 cm/s) TCD mFV values, the correlation coefficient between ICP and PI was 0.828 (p < 0.002) and 0.942 (p < 0.638 because of a low number of measurements), respectively (3, 4). It is an index easy to calculate, less influenced by the correct angle of insonation, and is more accurate in expressing the combination of many factors affecting the cerebral blood flow.
