Continuous FHR monitoring is done (both before and during labor) to evaluate postterm pregnancy (>42 weeks); after a nonreactive stress or NST; and in the presence of diabetes, preeclampsia, chronic hypertension, or fetal growth restriction. Normally, the rate is 100–150 beats/minute; accelerations occur with fetal movement, and a return of variable decelerations to baseline occurs with no evidence of decreasing baseline variability or increasing baseline rate.
