A professional liability insurer has posted this information on fetal monitoring for doctors.
The opening paragraph: "Initially, the fetal monitor was developed for the intrapartum period to better evaluate the status of the fetus during labor. Earlier identification of pending acidosis and hypoxia would alert the obstetric team, leading to more timely intervention and thus a significant reduction in the incidence of neonatal morbidity and mortality. Though clinical trials have failed to demonstrate a significant impact on morbidity and mortality, fetal monitoring is now essentially universal."
