Effect of Changes in Blood Pressure on Central Respiratory Activity
Stimulation of the arterial baroreceptors inhibits respiration(l) and this has been demonstrated experimentally either by applying pressure to an isolated carotid sinus or by stimulation of the carotid sinus nerve (which contains both baroreceptor and chemoreceptor afferents). However, the reflexly evoke systemic vasodilation, acting through the other intact baroreceptor areas will tend to lessen the respiratory effect.
