What is the effect of maternal hypotension on fetal heart rate?

Maternal hypotension, or low blood pressure in the mother, can adversely affect fetal well-being by decreasing blood flow and oxygen supply to the fetus. When the mother's blood pressure drops significantly, it can lead to a decrease in uterine perfusion, which compromises the oxygen delivery to the fetus. This lack of adequate oxygen may cause the fetal heart rate to decrease as the fetal body attempts to conserve energy and protect vital organ function. This response is vital for understanding the physiological connection between maternal health and fetal status during pregnancy and labor.

Recognizing this relationship is crucial for healthcare providers monitoring fetal heart rates, as a drop in fetal heart rate may indicate that the fetus is not receiving sufficient blood flow and oxygen due to maternal hypotension. By monitoring and addressing maternal blood pressure, interventions can be implemented to ensure both maternal and fetal health are maintained.
