Validation of Downloadable Mobile Snore Applications by Polysomnography (PSG)

• Conditions: Snoring; Apnea, Obstructive
• Interventions: Diagnostic Test: SnoreLab (smart phone application for snoring recording)

• Registration Number: NCT03890549
• Lead Sponsor: Chang Gung Memorial Hospital

Brief Summary

The aim of this study is to validate the downloadable mobile snore applications by polysomnography.

Detailed Description

Obstructive sleep apnea(OSA) is characterized by multiple episodes of upper airway collapse during sleep and considered as a major health issue worldwide due to comorbidity with obesity, hypertension, diabetes and more advanced cardiovascular diseases. The noisy sounds of snoring caused by OSA bother bed partner sleepless and lead to long-term health problems. Mobile snore applications are convenient and accessible for patients to monitor the progress of OSA by themselves, but there are no reliable PSG-validated applications.
