Facts
A pregnant woman arrived at Benefis Hospital in Great Falls, Montana, past her expected due date. An independent OB/GYN on call examined the patient’s prenatal records and found nothing significantly noteworthy. An attending nurse placed an electronic fetal heart rate monitor (EFM) on the woman’s abdomen, producing a fetal heart rate (FHR) record in relation to her contractions. This data can indicate whether the fetus is sufficiently oxygenated or at risk of hypoxic brain injury due to low oxygen supply.
