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 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 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.

However, its use in patients with pulmonary hypertension has not been properly evaluated. 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. It is a non-invasive method of assessing vascular resistance with the use of Doppler ultrasonography.

Background: Transcranial Doppler (TCD) pulsatility index (PI) has traditionally been interpreted as a descriptor of distal cerebrovascular resistance (CVR). We sought to evaluate the relationship between PI and CVR in situations, where CVR increases (mild hypocapnia) and decreases (plateau waves of intracranial pressure-ICP). 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.

2021-04-23 · The association between fetal growth in utero and disease in later life was first proposed by Barker in the 1990s and is supported by further studies over past decades.1–4 The fetal umbilical artery Doppler (UAD) pulsatility index (PI) measurement serves as a surrogate marker for the well-being of the fetus in utero through assessing impedance within the feto-placental circulation and is an indirect measure of resistance to flow within the placental vasculature. 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. Pulsatility Index > 50% may indicate marked venous congestion (thin patients may exhibit pulsatility in health). Figure 3 - RAAS activation in the physiology of Hyponatremia and AKI. RAAS stimulates proximal tubule sodium retention, loss of free water clearance, and reduced renal blood.
