One problem with airplane dining is that parched cabin air quickly evaporates nasal mucus, which helps odor receptors function.

Regular use of the nasal airflow-inducing maneuver has been shown to improve both subjective and objective measures of olfactory function.

Objective To explore the influence of earlier nasal continuous positive airway pressure (NCPAP) applying on pulmonary function, and evaluate the clinical results of the early application of NCPAP.
