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

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 openin...

Description
Summary: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 Patients with OSA and established therapy using NM and complaining about mouth dryness (n = 29) underwent three polysomnographies (PSGs) using NM, ONM or a nose mask in combination with an oral shield (NMS). Mask leakage was continuously documented and objective sleep quality was assessed. There were significant differences in the apnea-hypopnea-index (AHI) between ONM (8.5/h; SD 6,7) and NM/nasal mask combined with oral shield device (NMS) (2.6/h; SD 2,3; 2.7/h; SD 2,6) (p
