1. Calculate Pulsatility Index (PI) for Accurate Fetal Health Assessment
The pulsatility index (PI) is a measure of the pulsatile flow in a blood vessel. It is calculated as the difference between the peak systolic velocity and the end-diastolic velocity, divided by the mean velocity. The PI is a dimensionless number that is typically expressed as a percentage. A normal PI is less than 1.0. … Read more
