Noninvasive measurement of fetal and neonatal blood flow.
A newly developed doppler ultrasound flow measuring instrument was applied to determination of aortic arch blood flow in 6 near-term fetuses and 2 neonates and to umbilical cord flow in 2 fetuses. The method and results are presented and indicate good agreement between this noninvasive technique and expected values for aortic arch flow in human fetuses and neonates.
