What effect can maternal hyperventilation have on fetal heart rate?

Maternal hyperventilation results in excessive carbon dioxide (CO2) elimination from the body, leading to a state of respiratory alkalosis. This change in the mother's blood pH can cause vascular constriction in the placenta, decreasing blood flow to the fetus. As a consequence of reduced placental perfusion and oxygen delivery, the fetus may experience bradycardia, which is a decrease in the heart rate, as it struggles to cope with diminished oxygen supply. Thus, the relationship between maternal hyperventilation and fetal heart rate is significant, with the potential for altered fetal heart rate patterns that reflect the condition of fetal well-being. Such effects underscore the importance of monitoring maternal respiratory status and its implications for fetal health.
