If fetal arterial pressure begins to fall below normal levels: - ANSWER✔✔-

A. BARORECEPTORS CAUSE VASOCONSTRICTION AND INCREASE

THE FHR


An increase in arterial blood pressure produces vessel distension and

causes arterial baroreceptors to send neuronal messages to the

cardioinhibitory center, which in turn causes rapid slowing of the fetal

heart rate via the parasympathetic vagus nerve. A decrease in arterial

pressure results in an increased heart rate.

vein, venous return to the fetal right atrium is reduced, producing a reflex

tachycardia. This pattern often is observed as a shoulder on the FHR

monitor strip immediately before the abrupt variable FHR deceleration
