title: Body Position May Influence Oronasal CPAP Effectiveness to Treat OSA.
abstract: CPAP applied by a nasal mask is the gold standard treatment of obstructive sleep apnea. Oronasal masks are an alternative interface that can be used, especially in subjects with predominant oral breathing. However, oronasal masks have higher costs, are associated with larger leaks and higher residual apnea-hypopnea index, and in some cases may be ineffective.
