III. Interpretation

  1. Reactive (Normal)
    1. Two or more Fetal Heart Rate increases in 20 minutes
    2. Accelerations increase by 15 beats for 15 seconds
    3. Related to fetal movement
  2. Non-reactive
    1. Monitoring for two 20 minute periods
    2. Neither period yields adequate accelerations
    3. Adjuncts to assist fetal activity fail
      1. Acoustic stimulation
      2. Manual stimulation
      3. Glucose drink

IV. Management

  1. Reactive Nonstress Test
    1. Reassuring for fetal well being for 3-4 days
    2. Follow daily Fetal Kick Counts
  2. Non-Reactive Nonstress Test
    1. Perform Oxytocin Challenge Test (OCT)
    2. Perform Biophysical Profile
