What role does the fetal heart rate play in determining the health of the newborn?

The fetal heart rate is a critical indicator of the newborn's health, particularly in terms of oxygenation levels. During pregnancy, the heart rate can provide insight into how well the fetus is receiving oxygen. A normal fetal heart rate suggests that the baby is likely to be well-oxygenated, while abnormal heart rates may indicate potential issues such as fetal distress or hypoxia. Continuous monitoring of fetal heart rate during labor can help healthcare providers make necessary interventions to ensure the safety and well-being of the newborn.

Other options, while they may relate to various aspects of fetal and newborn evaluation, do not serve the same direct purpose in indicating oxygenation levels. Physical appearance and gender confirmation are not influenced by heart rate dynamics in a relevant clinical context, and while congenital defects can sometimes be indicated through various examinations and screenings, the heart rate is not specifically used to assess that risk.
