What is the test Nepstress?

Fetal Nonstress test is a way to measure the heart rate of the fetus during the third trimester. It is usually given only after the 28th week of pregnancy and is considered non -invasive because it does not emphasize the mother or child. Usually it consists of two belts chained around the mother's waist, one watching her contractions and watching the child's heart rate as he moved. Slow heart rate in the fetus during movement may indicate lack of oxygen, which tells doctors that something can be bad and should be quickly corrected.

This type of test is usually performed after a week, because children are not sufficiently developed to respond to the non -ststress test before this period of pregnancy. The test is usually ordered by a doctor when the mother notices reduced fetal movement, is considered a high risk or delayed. In general, if there is a reason to assume that the child does not have enough oxygen, a non -digestive test will be performed. Fortunneting to invasive because both belts simplye wrapped around the mother's waist anywhere from 20 minutes to an hour.

During the Nonstress test, the fetal heart rate and the contraction are graphs on the computer monitor. The aim is to see that the child's heart rate increases with each of its movements because it suggests that oxygen levels are adequate. It is said that a child whose heart rate is within a normal range of 120 to 160 beats per minute has a reactive test NEBSTERSS, while a child whose heart rate seems to remain the same during movement has a non -real Nesterss test. This can be caused by problems with the placenta or umbilical cord through which the child receives its oxygen. On the other hand, this may mean that the child is asleep, in which case he can usually be awakened by a mother who drinks a sweet drink; Sometimes the doctor can also use a loud buzzer to the child.

test of this kind can be offered in a medical office even if it is most oftenstated in a standby room or work and delivery rooms when a fetus problem is suspected. In some cases, this test is performed when otherwise normal pregnancy continues after the due date, because it is important to monitor delayed children to ensure that they are not in need. Fortunately, the only danger of having a non -Ststrass test is incorrectly data interpretation, making them one of the safest tests offered.
