Doppler blood velocity waveforms were analyzed from the umbilical artery as an indication of fetal well-being. Since the ratio of systolic to diastolic peak flows (A/ B) reflects placental vascular resistance, an abnormality of this value may accurately predict compromised fetuses. Twenty-one studie

Pulsed-Doppler examinations of blood-flow velocities in the umbilical ar- tery were carried out before and after 15 diagnostic cordocenteses and 34 fetal blood transfusions into the umbilical vein. There were decreases in the systolic/diastolic ratio (A/B) ( p < 0.01), the pulsatility index (PI) (p
