Efficacy of a Smart Antisnore Pillow in Patients with Obstructive Sleep Apnea Syndrome

Abstract

Objective. Untreated obstructive sleep apnea syndrome (OSAS) increases the risk of cardiovascular, dementia, and motor vehicle accident events. However, continuous positive airway pressure (CPAP) which is the gold standard treatment is not acceptable for many patients with OSAS. Development of devices for the patients of nonadherence to CPAP is necessary. Materials and Methods. We evaluated the effect of the smart antisnore pillow (SAP) in patients with OSAS in a prospective, noncontrolled, nonrandomized, pilot study. According to the apnea-hypopnea index (AHI), they were divided into two groups: mild-to-moderate OSAS group and severe OSAS group. Single-night polysomnography (PSG) with application of a SAP was performed. Thirty patients, 15 males and 15 females, 33–82 years old (mean age, $59.3\pm 12.9$ years), completed the smart antisnore pillow therapy test. Among them, 23 patients had mild-to-moderate OSAS. Results. The SAP significantly improved the snore number ( $p=0.018$ ), snore index ( $p=0.013$ ), oxygen denaturation index ( $p=0.001$ ), total AHI ( $p=0.002$ ), and supine AHI ( $p=0.002$ ) in the mild-to-moderate OSAS group, but there was no significant improvement in the severe OSAS group. Conclusions. We concluded that the SAP is an effective positional therapy device for patients with OSAS of mild-to-moderate severity.
