What does NSFM mean in UNCLASSIFIED

Non Stress Fetal Monitoring (NSFM) is a non-invasive procedure used to assess fetal well-being by evaluating the fetal heart rate (FHR) and fetal movements. It is a routine part of prenatal care and is typically performed during the third trimester of pregnancy.

NSFM primarily measures the FHR and its variability, which is a measure of fetal heart rate fluctuations. It also records fetal movements, such as accelerations and decelerations. These parameters provide information about fetal health and well-being.

NSFM is typically performed in a doctor's office or hospital. A pregnant woman lies on her side with an external transducer attached to her abdomen. The transducer emits ultrasound waves that detect the fetal heart rate and movements. The data is recorded and analyzed to evaluate fetal health.

NSFM is a safe and effective way to monitor fetal well-being. It can help identify fetal distress, such as decreased heart rate variability or decelerations, which may indicate the need for further evaluation or intervention.

While NSFM is a valuable tool, it is not foolproof. False negatives, where the test does not detect fetal distress, can occur. Additionally, NSFM may not always be reliable in pregnancies with certain conditions, such as maternal obesity or multiple gestations.

NSFM is typically performed once or twice a week during the third trimester of pregnancy. The frequency of testing may increase towards the end of pregnancy or if there are concerns about fetal well-being.

If an abnormal result is obtained, the healthcare provider will evaluate the situation and determine the next steps. Further testing, such as biophysical profile (BPP) or Doppler ultrasound, may be necessary to confirm fetal distress.
