Why the study?
Does arterial hypoxia reduce the effectiveness of the carotid baroreflex in producing cardiac slowing in dogs?

Arterial hypoxia suppresses the vagal component of baroreflex bradycardia through both aortic chemoreceptor reflexes and direct effects on the central nervous system.
No takes yet. Share an insight, caveat, or question.
Hypoxia may blunt baroreflex bradycardia; leaves open translation of aortic chemoreceptor and CNS mechanisms to humans.
Pisarri et al. (1984) studied this question.
