2021-04-10 · OBJECTIVES: To calculate the normal range for the fetal middle cerebral artery (MCA)/uterine artery pulsatility index (PI) ratio in the third trimester of pregnancy and to assess its value, compared with that of the MCA/umbilical artery PI ratio, in predicting an unfavorable outcome of pregnancies complicated by pre-eclampsia. PI’s values range from 0.02% for very weak pulse to 20% for extremely strong pulse. The perfusion index varies depending on patients, physiological conditions, and monitoring sites. Be-cause of this variability, each patient should establish his own “normal” perfusion index for a given location and use this for monitoring purposes. Chen M, Chen H, Yang X, et al. Normal range of intracranial translucency (IT) assessed by three-dimensional ultrasound at 11+0 to 13+6 weeks in a Chinese population.

Pulse oximeter fingertip with Plethysmograph and Perfusion Index, Portable Blood Oxygen Saturation Monitor for Heart Rate and SpO2 Level, O2 Monitor Pulse  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.

Therefore, the main study objective was to derive normative new day-cycle-based reference ranges for the UtA-PI during the entire cycle from days 1 to 34 according to the isolated time effect and potential confounders such as age and parity.

See also. cerebroplacental ratio; pulsatility index (ultrasound) 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 [1] and in those who have been implanted with left ventricular assist device (LVAD). Pulsatility index (PI) = (systolic velocity - diastolic velocity / mean velocity) In the normal fetus, the resistance to flow (impedance) decreases in the umbilical artery due to increased numbers of tertiary stem villi as the placenta matures. An increasing number of laboratories are now offering colour flow-directed measurements such as pulsatility and resistance indices as well as flow velocities. 2,13,26,29,32,39,57,60 Some colour flow studies are still considered investigational in the USA. The pulsatility index is calculated by the following formula: Normal Middle Cerebral Artery Pulsatility Index GA = Gestational Age. � = Predicted value - (2 � 0.184 � predicted value). �� = Predicted value + (2 � 0.184 � predicted value).
