Biophysical Profile and Color Doppler Ultrasound in the High Risk Pregnancy Presented by: Dr. Farzad Afzali Kasra Ultrasound Clinic   • BPP is applying to detect prenatal asphyxia • Doppler ultrasound is a modality for detecting fetal hypoxia and acidosis • Doppler can also predict later pre- eclampsia at the 24-26 gestational weeks.   • Hypoxia: Low oxygen tension • Asphyxia: Low oxygen and high CO2 • Ischemia: Drop in blood flow Comment So, Doppler ultrasound can predict fetal distress sooner than BPP   • Prediction of the effect of an asphyxial insult on the fetus requires a measure of:
