What is a Nonstress Test?
A Nonstress Test, commonly referred to as NST, is a prenatal diagnostic procedure used to assess the fetus's well-being during pregnancy. This non-invasive test involves monitoring the baby's heart rate and movements to ensure they respond as expected to their movements and uterine contractions.
During a Nonstress Test, a specialized machine records the fetal heart rate, which usually increases when the baby moves. The test helps healthcare providers evaluate the baby's oxygen and nutrient supply and overall health in the womb.
The test is typically recommended when there are concerns about the baby's health or well-being during pregnancy. Common reasons for an NST include decreased fetal movement, high blood pressure in the mother, gestational diabetes, or if the pregnancy has passed its due date.
A specialized monitoring machine records the fetal heart rate during the test, offering a real-time glimpse into the baby's cardiac activity. It is important to note that a healthy fetal heart rate typically increases when the baby makes movements. Therefore, this test assesses explicitly whether the baby's heart rate responds appropriately to its motions and uterine contractions.
