Normal Values
Normal values indicate that the fetus is not in distress by showing a fetal heart rate between 120 to 160 beats per minute, with variability of 5 to 25 beats per minute from the baseline or normal fetal heart rate.
It is not uncommon for the fetal heart rate to drop slightly during a contraction, since placental blood supply is diminished under the compression of a uterine contraction, as long as the FHR recovers quickly once the contraction has stopped.
