What is the Nichd category?
NICHD criteria for category I II and III FHR tracings – UpToDate. 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. Category III tracings are predictive of abnormal fetal acid-base status at the time of observation …
How many categories are there in Nichd fetal heart rate tracing?
The American College of Obstetricians and Gynecologists (ACOG), the Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the Society for Maternal-Fetal Medicine developed a new three-tiered classification of fetal heart rate abnormalities and a system for interpreting these abnormalities …
What is a Category 2 FHR tracing?
Selected category II FHR abnormalities. Late decelerations without loss of variability or accelerations. Fetal tachycardia. Variable decelerations without loss of variability or accelerations. Loss of variability without decelerations.
What is Category 3 FHR?
NICHD Category III (CIII) fetal heart rate tracing (FHR) is defined as having either sinusoidal pattern or absent baseline variability plus recurrent late decelerations, recurrent variable decelerations, or bradycardia. We sought to describe demographics and neonatal outcomes associated with CIII.

What is interobserver and intraobserver reliability?
The intraobserver reliability assessed the reproducibility of each observer for each measurement technique. The interobserver reliabilities were obtained to assess the overall agreement among the three observers for all methods and for each method as well.
What is a Category 1 fetal tracing?
Category I : Normal. The fetal heart rate tracing shows ALL of the following: Baseline FHR 110-160 BPM, moderate FHR variability, accelerations may be present or absent, no late or variable decelerations, may have early decelerations. Strongly predictive of normal acid-base status at the time of observation.
What is a Category 1 FHR?
Where is the NICHD?
NICHD’s budget in 2015 was an estimated $1.3 billion, which supported research at institutions, universities, and organizations throughout the world, as well as research conducted by NICHD scientists on the NIH campus in Bethesda, MD, and at other facilities.
What is the definition of FHR in NICHD?
NICHD: National Institute of Child Health and Human Development; FHR: fetal heart rate; bpm: beats per minute; sec: seconds. * “Gradual” and “abrupt” changes are defined as taking ≥30 seconds or <30 seconds, respectively, from the onset of the deceleration/acceleration to its nadir/peak.
What are the different categories of FHR tracings?
Category I. Category I FHR tracings include all of the following: • Baseline FHR: 110-160 bpm • Baseline FHR variability: moderate • Late or variable decelerations: absent • Early decelerations: present or absent • Accelerations: present or absent. Category II. Category II FHR tracings include all tracings not categorized as Category I or Category
When did the National Institute of Child Health and Human Development ( NICHD )?
The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) convened a series of workshops in the mid- 1990s to develop standardized and unambiguous definitions for fetal heart rate (FHR) tracings, culminating in a publication of recommendations for defining fetal heart rate characteristics ( NICHD, 1997 ).
How is the fetal heart rate ( FHR ) determined?
Fetal heart rate patterns are defined by the characteristics of baseline, variability, accelerations, and decelerations. The baseline FHR is determined by approximating the mean FHR rounded to increments of 5 beats per minute (bpm) during a 10-minute window, excluding accelerations and decelerations and periods of marked FHR variability (>25 bpm).
