[A multicenter trial of a device for treating obstructive sleep apnea by continuous positive pressure].

The efficacy and tolerance of a nasal CPAP device marketed in France (Pression +, Sefam) for the treatment of obstructive sleep apnoea syndromes have been evaluated in a co-operative trial including 12 patients. This study confirmed the efficacy of nasal CPAP on sleep parameters: total sleep time was increased; light non-REM sleep was diminished; slow-wave sleep and REM sleep were augmented; sleep apnoeas were eliminated completely or almost completely; oxygen saturation was markedly improved. At one month follow-up, most clinical features were improved; daytime blood gases showed little change but the number of red cells was decreased. On the whole, the tolerance was good in this highly motivated group of patients: eleven patients (92%) were willing to continue their home treatment with the same device. Most difficulties were due to the making of a tailored molded nasal mask and its use during sleep.
