There are two methods of fetal heart rate monitoring in labor. Continuous fetal heart rate monitoring is widely used during labor even in low risk pregnancies.

Interpretation Of The Electronic Fetal Heart Rate During Labor American Family Physician

Consensus is necessary to define and interpret accurately the different fhr patterns.

Fetal heart rate labor. Mild variable decelerations are present. The method that is used depends on the policy of your ob gyn or hospital your. Electronic fetal monitoring is a procedure in which instruments are used to continuously record the heartbeat of the fetus and the contractions of the woman s uterus during labor.

The superiority of noninvasive fetal ecg was maintained for stages 1 and 2 of labor and increases in body mass index. Baseline fetal heart rate definition average fhr rounded to 5 bpm during a 10 minute period but excludes periods of marked increased fhr variability segments of baseline that differs by more than 25 bpm must compromise at least 2 minutes out of 10 minute segment normal range is 110 160 bpm nichd always documented as a range. The root mean squared error compared with fetal scalp electrode derived fetal heart rate was 4 8 2 0 bpm for noninvasive fetal ecg and 14 3 8 2 bpm for ultrasound.

Fetal tachycardia with possible onset of decreased variability right during the second stage of labor. The normal fhr tracing include baseline rate between 110 160 beats per minute bpm moderate variability 6 25 bpm presence of accelerations and no decelerations. Maternal heart rate patterns recorded by electronic fetal monitors closely resemble fetal patterns.

Auscultation is a method of periodically listening to the fetal heartbeat. Baseline fetal bradycardia the absence of decelerations in the second stage of labor and marked accelerations coinciding with uterine contractions may suggest a maternal heart rate rather than an. Fetal heart rate is 170 to 180 bpm.
