Reducing daytime leg fluid accumulation using electrical stimulation of the legs to decrease overnight rostral fluid shift and consequent sleep apnea

Obstructive sleep apnea (OSA) is a common disorder affecting 6% of the adult population and increases risk of cardiovascular mortality. OSA occurs due to repeated full or partial collapse of the upper airway during sleep. One contributor to airway collapse during sleep is the overnight shift of fluid from the legs towards the neck where it accumulates. Increased daytime fluid accumulation in the legs magnifies this, resulting in more fluid accumulation in the neck and increased OSA severity.
