The pulsatility index of the anterior tibial artery (50th centile) increased slightly from 3.29 at 23 weeks of pregnancy to 4.09 at 42 weeks. The 5th and 95th centiles were calculated, as was the 95% confidence interval of the 5th and 95th centiles. As fetal Doppler examination in the late second and third trimesters is rarely performed routinely where no indication exists, these charts are of potential utility in the setting where referrals to a fetal assessment unit are made for fetal growth, amniotic fluid, biophysical profiling and fetal Dopplers.Figure 1 -Figure 2 -12Umbilical artery pulsatility index: mean, 5th and 95th percentiles

Results: There was a significant variation in all the PSV, RI and PI values measured, both in the 1-beat series diagnosis of poor fetal we index (PI) and resistive index (RI) of left and right MCAs of fetuses suspected to have intrauterine ultrasound examination of fetuses suspected to have IUGR. RESULTS: Mean uterine artery pulsatility index was higher in fetal growth restriction (1.37 and umbilical Doppler PI. >95th percentile on ultrasound scan. 31.

To assess the risk, pulsed Doppler ultrasound (US) is used to evaluate the flow velocity waveform in for status of the fetus is worse than the PI suggests.

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
