A recent study shows that acupuncture as a treatment for obstructive sleep apnea (OSA) has immediate effects in reducing nocturnal respiratory events, sleep disruptions, and desaturations (low oxygen levels in the blood). The researchers hypothesize that this improvement is due to acupuncture’s effects on serotonergic pathways and also acupuncture’s anti-inflammatory effects.Acupuncture Testing Procedures Laboratory findings used electroencephalography, electromyography, and electrocardiography. This tested respiration, mouth flow, and pulse oximetry with the use of an oximeter. Subjects were chosen for the study from a randomized process. Blinded independent researchers were used.
