NICHD criteria for category I, II, and III FHR tracings

NICHD criteria for category I, II, and III FHR tracings
Category I
All of the following criteria must be present. Tracings meeting these criteria are predictive of normal fetal acid-base balance at the time of observation.
Baseline rate: 110 to 160 bpm
Moderate baseline FHR variability
No late or variable decelerations
Early decelerations may be present or absent
Accelerations may be present or absent
Category III
Category III tracings are predictive of abnormal fetal acid-base status at the time of observation. Prompt evaluation is indicated and most parturients will require expeditious intervention, such as change in position, treatment of hypotension, and discontinuation of any uterotonic drugs being administered. Category III tracings include either (1) or (2) below.
(1) Absent baseline FHR variability and any of the following:
  • Recurrent late decelerations
  • Recurrent variable decelerations
  • Bradycardia
(2) Sinusoidal pattern
Category II
FHR tracing does not meet criteria for either category I or III and is considered indeterminate.
NICHD: National Institute of Child Health and Human Development; FHR: fetal heart rate; bpm: beats per minute.
