fetal heart rate
The fetal heart rate is continuously monitored via the CTG device during the entire performance test.
Umbilical cord artery pulsatility index
(systolic velocity - diastolic velocity) / mean velocity
Umbilical cord artery resistance index
(systolic velocity - diastolic velocity) / systolic velocity
umbilical cord artery S/D ratio
(S = maximum systolic flow velocity; D = maximum diastolic flow velocity)
