Nasal versus oronasal continuous positive airway pressure masks for obstructive sleep apnea: Is this really a key point of effectiveness?

摘要

Bakker et al. analyzed that changing from a nasal to oronasal mask increased leak and residual apnea-hypopnea index (AHI) without an influence on the therapeutic pressure requirement in obese patients with obstructive sleep apnea (OSA) [1]. The findings of the current study highlight mask leak as the major difficulty in the use of oronasal masks.We read with interest this study that revealed if there is a variation in pressure levels in patients with OSA by changing the type of facial nasal interface. The authors in this study provide original observations with important implications for the effectiveness of treating patients with OSA and continuous positive airway pressure (CPAP) [1]. However, there are some aspects that may be of interest to perform an analysis, especially those related to the possible pathways of controlling these changes in pressure and residual leak levels.
