Nasal Continuous Positive Airway Pressure for Nonapneic Snoring?

Helmuth Rauscher MD1; Dieter Formanek MD1; and Hartmut Zwick MD, FCCP1

1 From the Pulmonary Department, Krankenhaus Lainz, Vienna, Austria

The feasibility of nasal continuous positive airway pressure (CPAP) for heavy snoring associated with daytime sleepiness was studied in 118 consecutive patients with an apnea hypopnea index below 5. Fifty-nine of them reported daytime sleepiness in a questionnaire and were offered treatment with nasal CPAP. Whereas 48 patients refused it, the remaining 11 (19%) accepted nasal CPAP for home therapy. Acceptors and refusers did not differ in sleep structure, but acceptors had slightly more sleep-disordered breathing events per hour of sleep than refusers. The pressure needed to abolish snoring in these 11 patients was 7.3±1.6 cm H2O. Six months after prescription, the built-in time counters of the patients' devices were read. By dividing the hours of operation by the days since initiation of treatment, we found a mean daily use time of only 2.8±1.5 h. Nevertheless, eight patients (73%) reported that their sleepiness had improved with therapy. We conclude that only a minority of nonapneic snorers accept treatment with nasal CPAP on a long-term basis and that this subgroup is not predictable from polysomnography.

Key Words: daytime sleepiness • nasal continuous positive airway pressure-compliance • snoring • upper airway resistance syndrome
