A "normal" baseline fetal heart rate usually falls between 120 and 160 beats per minute. Your doctor might administer oxygen in response to late decelerations. Content is reviewed before publication and upon substantial updates. The primary benefit of monitoring is early detection of fetal distress, but there is also a risk of false-positive interpretations of the readings (also called tracings). Also, you can take certain steps to treat late decelerations and improve fetal oxygen supply. Its unlikely that your fetus is receiving insufficient oxygen to centrally located organs if theyre sustaining a stable baseline heart rate with a reassuring variability.
