The fetal middle cerebral artery (MCA) pulsatility index (PI) is a key parameter used in fetal middle cerebral arterial Doppler assessment . It is calculated by subtracting the end-diastolic velocity (EDV) from the peak systolic velocity (PSV) and then dividing by the time-averaged (mean) velocity (TAV): PI = (PSV - EDV) / TAV. 2020-01-02 · Pulmonary Artery Pulsatility Index (PAPi) is a recently described hemodynamic index, which has been used to predict right ventricular failure in those with inferior wall infarction and in those who have been implanted with left ventricular assist device (LVAD).

RESULTS: Pulsatility and resistance indices decreased along all measurement locations from proximal to distal. The pulsatility index decreased significantly from location II to III and from I to II. However, the decrease was more pronounced along the Atlas slope than in the straight-vessel section below. Jun 15, 2020 Abstract. Pulsatility index (PI) is defined as the difference between the peak systolic flow and minimum diastolic flow velocity, divided by The aim of our study was to evaluate whether there is an association between the pulsatility indexes (PI) of the middle cerebral artery (MCA) measured by Aug 14, 2018 Background/Aims: In clinical settings, the pulsatility index (PI) has become a widely used tool for monitoring obstetrics or other vascular Jul 1, 1997 BACKGROUND: The pulsatility index (PI) and the resistive index (RI) are used as pulsed-wave Doppler measurements of downstream renal Feb 4, 2012 Transcranial Doppler (TCD) pulsatility index (PI) has traditionally been interpreted as a descriptor of distal cerebrovascular resistance (CVR). The Pulsatility Index (PI) is a measurement of the flow pulse through the pump.
This is the pulmonary arterial pulse pressure divided by the right atrial pressure (right ventricular filling pressure). On 2-D-PCD, the Resistance Index (RI= (PSVEDV)/PSV= (peak systolic velocity-end diastolic velocity)/peak systolic velocity), the Pulsatility Index (PI= (peak systolic velocity-end diastolic velocity)/mean velocity= (PSV-EDV)/TAV), the systolic/diastolic ratio S/D (systolicvelocity/ diastolic velocity) were calculated on three consecutive wave forms which were used to evaluate uterine artery resistance. The aim was to compare pulsatility index (PI) values recorded by the MediStim and Transonic flowmeters in two different clinical settings: (1) analysis of the flow patterns recorded simultaneously by both flowmeters in the same CABGs; and (2) evaluation of flow patterns under different levels of filter settings in the same grafts.

The pulmonary artery pulsatility index (PAPi), defined as [ (systolic pulmonary artery pressure – diastolic pulmonary artery pressure)/CVP], is a hemodynamic index originally used to predict RVF in inferior wall acute myocardial infarctions. Recently, PAPi has also been shown to be an independent predictor of postoperative RVF in continuous-flow LVAD recipients.35,36 PAPi is unique among the risk stratification tools in that it identifies not only patients with any degree of RV dysfunction Pulmonary artery pulsatility index (PAPi) = (systolic pulmonary arterial pressure − diastolic pulmonary pressure)/right atrial pressure. This is the pulmonary arterial pulse pressure divided by the right atrial pressure (right ventricular filling pressure). On 2-D-PCD, the Resistance Index (RI= (PSVEDV)/PSV= (peak systolic velocity-end diastolic velocity)/peak systolic velocity), the Pulsatility Index (PI= (peak systolic velocity-end diastolic velocity)/mean velocity= (PSV-EDV)/TAV), the systolic/diastolic ratio S/D (systolicvelocity/ diastolic velocity) were calculated on three consecutive wave forms which were used to evaluate uterine artery resistance.

Placental pulsatility index: a new, more sensitive parameter for predicting adverse outcome in pregnancies suspected of fetal growth restriction. Acta Obstetricia et Gynecologica Scandinavica , 96 (2), 216-222. 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 Recently, a method for non-invasive ICP measurements was suggested: the Pulsatile Index (PI) calculated from transcranial Doppler data assessed from the middle cerebral artery. In this thesis the relation between PI and ICP was explored in INPH patients during controlled ICP regulation by lumbar infusion.
