In fetal life, peripheral chemoreceptor stimulation by hypoxia or hypercapnia produces bradycardia and peripheral vasoconstriction (1, 2). After birth, however, the same stimuli cause hyperventilation ...
Peripheral and central chemoreceptors are crucial for the precise control of respiration. The carotid, aortic, and central chemoreceptors are functional even in fetal life (1, 2), but the transition ...
