sympathetic nervous system ↔ blood pressure

The sympathetic nervous system and blood pressure are linked through physiological responses to Obstructive Sleep Apnea, where apneas trigger simultaneous increases in both [1] and [2]. Furthermore, the barostatic system regulates blood pressure by modulating autonomic outflow to the sympathetic nervous system to maintain homeostasis [3].

measurementDuring the night, apneas and hypopneas associated with Obstructive Sleep Apnea (OSA) cause a transient rise in blood pressure of 30 mm Hg or more and increased activity of the sympathetic nervous system.

claimThe transient blood pressure and sympathetic nervous system changes associated with Obstructive Sleep Apnea become sustained over time and are detectable during the daytime.

procedureThe barostatic system regulates blood pressure through negative feedback: when blood pressure increases, baroreceptors in the carotid sinus are stretched, sending nerve traffic to the brainstem, which results in autonomic outflow that decreases heart rate and turns off the sympathetic nervous system to lower blood pressure.
