Fetal biophysical profile, or PBF, is a test that evaluates the well-being of the fetus from the third trimester of pregnancy and is able to evaluate the baby’s parameters and activities, based on body, respiratory movements, growth in amniotic fluid volume, and adequate heart rate.
These parameters are important because they reflect the functioning of the baby’s nervous system and its oxygenation status, so if any problems are identified, it is possible to perform the treatment as quickly as possible, the baby still in the womb.
- Fetal biophysical profile examination is particularly appropriate in cases of pregnancy at increased risk of complications.
- Which can occur in situations such as:.
In addition, some doctors may apply for the biophysical profile of the fetus only to ensure a successful pregnancy, even if the pregnant party presents a gestational risk, although there is no evidence of the benefit of this practice.
Examination of the biophysical profile of the fetus is performed in obstetric clinics, usually with an ultrasound to observe the baby and with the use of sensors that detect the heartbeat and blood flow.
For the test, pregnant women are advised to wear light and comfortable clothing, to be well fed to prevent hypoglycaemia, and to sit or lie down in a comfortable position.
With the completion of the fetal biophysical profile, the obstetrician can identify the following parameters:
In addition, fetal heart rate is also measured, measured by association with the fetal cardiotocography test.
Each evaluated parameter, within a 30-minute period, receives a score of 0 to 2, and the total result of all parameters is given with the following scores:
Depending on the interpretation of these results, your doctor will be able to identify life-threatening changes in your baby at an early stage and treatment can be done more quickly, which may include the need for preterm birth.
