All are true about antenatal umbilical aery Doppler except?
S/D Ratio of umbilical aery Doppler is increased in smokers. Decreased, absent or reversal of diastolic flow on umbilical aery Doppler suggests fetal IUGR and impending Fetal death. Fetal MCA S/D ratio is normally more than S/D ratio of umbilical aery. Fetal MCA S/D ratio is less than S/D ratio of umbilical aery Doppler in IUGR.
Decreased diastolic flow of umbilical aery is suggestive of IUGR
S/D Ratio of umbilical aery is less than S/D ratio of Fetal MCA
S/D Ratio is decreased in smoking females
Reversal of diastolic flow in umbilical aery Doppler suggests impending Fetal demise
