This study has been criticized for biases in patient selection (more patients were followed with CSTs, higher rates of low-birth-weight infants in the NST group), lack of standardization of test conditions or NST interpretation, and nonuniform follow-up of test results.

THE NON-STRESS TEST. Non-stress tests are performed to assist with the assessment of fetal well being during the antenatal period. Accelerations, along with other characteristics of the fetal heart rate; for example baseline, variability, presence or absence of spontaneously occurring decelerations are used, as a

Movement, heart rate and “reactivity” of heart rate to movement are measured for 20-30 The non stress test (NST) is a simple, noninvasive way of checking on your baby's health. The test, sometimes called a cardiotocography, records your baby's movement, heartbeat, and contractions. A nonstress test is a type of test done during pregnancy. It measures the heart rate of the unborn baby (fetus) in response to its movements. In most cases, the heart rate of a healthy baby increases when the baby moves. The nonstress test is usually done in the last trimester of pregnancy. Non- Stress Test (NST) 02/2013 A non-stress test (NST) is a simple and painless way to check on the well being of your baby.

in association with fetal movements. Non-Stress Test (NST) What is it? A non-stress test is a technique for evaluating how well the placenta is functioning and thus the well-being of the fetus in the uterus. By watching the response of the fetal heart rate to fetal movement, we can get a good idea of how well the placenta is meeting the fetus’ needs.

• if the NST does not meet criteria after 20 minutes, continue monitoring for up to 120 minutes The test is named “non-stress” because no stress is placed on the fetus during the test. How is an NST Performed? The test involves attaching one belt to the mother’s abdomen to measure fetal heart rate and another belt to measure contractions.

By eating healthy food, staying fit and not overweight, it is probably possible to delay or even prevent from getting diabetes later in life. The glucose tolerance test is

Interpretation • based on presence or absence of accelerations of fetal heart rate. • interpretation of the NST is dependent on gestational age.

A nonstress test, also known as fetal heart rate monitoring, is a simple and non-invasive test performed after 28 weeks of pregnancy. THE NON-STRESS TEST.

It measures the heart rate of the fetus in response to its movements. The nonstress test is called so because it does not pose any physical stress to you or your fetus (1).

It is performed using an external fetal heart rate monitor to assess the fetal heart rate response to fetal movements.

The concept behind a non-stress test is that adequate oxygen is required for fetal activity and heart rate to be within normal ranges. When oxygen levels are low, the fetus may not respond normally. Low oxygen levels can often be caused by problems with the placenta or umbilical cord. THE NON-STRESS TEST.
