Flowmetry

Alongside the traditional ultrasound tools useful for monitoring the progress of pregnancy and fetal development, there are some tests that are prescribed only in certain circumstances and have specific purposes. This is the case of the fetal doppler that allows you to perform a flowmetry (velocimetry).

Flowmetry: when it is performed

It is an exam that it is not done routinely during pregnancy, but in case of pregnancy complications on mother and baby, such as:

  • hypertension,
  • growth retardation in the uterus,
  • abnormal amniotic fluid,

In association with the reading of biometric data it allows you to make an assessment of some key areas such as the femur, the abdomen. In short, the doppler is able to monitor the growth of the fetus and to tell if the blood flow is sufficient
  • blood flow study in uterine arteries. Very useful in case of maternal hypertension
  • blood flow study in arteries of the fetal brain. It provides a direct indication of the fetal status

Homemade Doppler

In recent years there has been an increase in the diffusion and commercial production of homemade doppler.
In short, future parents can buy a fetal doppler and use them at home. It is good to know that these instruments have nothing to do with the doppler performed by the specialist during pregnancy. These tools only listen to the baby's heart when its position in the belly allows it.
