20. • Heartmate 2/3 -> “Pulsatility Index” (PI) • Magnitude of the pulsatility is measured and averaged over 15 second period • -> Pulsatility Index (Range: 1-10) • Pulsatility correlates with PI. Pulsatility = PI Pulsatility = PI. 21. Pulmonary artery pulsatility index (PAPi) is a haemodynamic parameter that is derived from right atrial and pulmonary artery pulse pressures. A number of reports have described the prognostic value of PAPi in patients with advanced heart failure and cardiogenic shock. However, the derivation and physiological interpretation of this parameter have received little attention.

Pulsatility Index (PI) is defined as the difference between peak systolic and enddiastolic flow velocity, divided by the time-averaged flow velocity. From: Gynecologic Oncology, 2012.

Head injury is an important factor in children's morbidity and mortality. 2021-02-04 ABSTRACT : OBJECTIVE.
Pulsatility index (PI) is currently the most commonly used index for the evaluation of UtA Doppler waveform patterns. However, previously published studies on UtA Doppler evaluation throughout pregnancy have used a variety of Doppler indices 3, 5, 6, 10, 12, 14, 15, 17, 19 - 22 or scoring systems 13, 16, 18.
Pulsatility index is better than ankle-brachial doppler index for non-invasive detection of critical limb ischaemia in diabetes. Janssen A(1). Author information: (1)Department of Internal Medicine, St. Agatha Hospital, Cologne, Germany. firstname.lastname@example.org Gosling’s pulsatility index (gPI) which describes the pulsatility of the TCD waveform has shown not to be an accurate estimator of ICP and cerebrovascular resistance; however, it does not mean The prognostic value of pulsatility index, flow velocity, and their ratio, measured with TCD ultrasound, in patients with a recent TIA or ischemic stroke.

We aim to assess the use of PAPi in the evaluation of patients with PAH. Pulsatility index (PI) is defined as the difference between the peak systolic flow and minimum diastolic flow velocity, divided by the mean velocity recorded throughout the cardiac cycle.

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 High uterine artery pulsatility index (UtAPI) at the end of the first trimester is associated with altered placentation and elevated risk for adverse pregnancy outcomes.
