supply measurement, Doppler ultrasound
Doppler ultrasonography is a method during which the resistances and the blood stream speeds are measured in the mother’s and/or baby’s (fetal) vessels. This indirectly gives indications as to whether the baby is being adequately supplied in the womb.
Measuring the flow of blood using Doppler ultrasonography is in no way different for the pregnant woman and unborn baby than a standard ultrasound scan. The extra information gained helps, in case of a high-risk pregnancy or abnormal growth of the child, to initiate therapeutic steps in good time or to estimate the right time for the baby’s birth.
