Prevention of leakage due to mouth opening through applying an oral shield device (Sominpax (TM)) during nasal CPAP therapy of patients with obstructive sleep apnea

摘要

Background/objective: The first line treatment for obstructive sleep apnea (OSA) is nasal continuous positive airway pressure (nCPAP), for which a variety of masks are available. While nasal masks (NM) are the first choice; oronasal masks (ONM) are also frequently used to prevent mouth dryness resulting from mouth opening. Our cross-sectional, prospective, randomized, un-blinded study addressed the efficacy of wearing an oral shield in addition to NM in preventing mouth leakage
