Nonstress test
Noninvasive procedure for evaluation of fetal well being. Performed during third trimester, A doppler will monitor F HR and A tocotransducer to monitor uterine contractions are attached externally on moms abdomen. The mom will have a button to press when she feels fetal movement.
A nonstress test, also known as NST, is a prenatal diagnostic test that is performed to monitor the fetal heart rate and uterine contractions. This test is usually recommended for high-risk pregnancies, such as those with a history of premature delivery, preeclampsia, gestational diabetes, or other medical conditions.
During the test, the mother will lie on her back or side while a fetal monitor is attached to her abdomen. The monitor measures the fetal heart rate and records any changes that occur. The test usually takes around 20-30 minutes to complete, but may take longer if there are any concerns.
The nonstress test is considered noninvasive as it does not involve any needles or other invasive procedures. It is also painless and does not cause any discomfort to the mother or fetus.
The results of the NST can be either reactive or nonreactive. A reactive result means that the fetal heart rate increases appropriately in response to fetal movement, indicating that the fetus is healthy and receiving enough oxygen. A nonreactive result, on the other hand, may indicate that the fetus is not getting enough oxygen or may be in distress.
If the nonstress test is nonreactive, further testing may be needed to determine the cause of the result and to ensure the health of the fetus. Overall, the nonstress test is a valuable tool for monitoring high-risk pregnancies, and can help detect potential complications before they become more serious.
