INTRODUCTION: At the beginning of treatment with CPAP due to sleep apnea-hypo- pnea syndrome (SAHS), different types of problems may arise that prevent its correct use or even abandonment. Therefore, it is necessary to know which the main complications are to inform the patient and to give solutions early.
MATERIAL AND METHOD: We studied 120 patients diagnosed with SAHS who be- gan the treatment with nasal CPAP. We carried out questionnaires to assess their sleep be- fore treatment and to identify factors that influence the adaptation to CPAP. After at least 2 months, questionnaires were asked about complications and tolerance to the treatment.
RESULTS: The discomfort caused by the mask and/or fixation straps were the most frequent complications, as well as the in- juries caused by them (callosities, excoriations) disappearing in 2-3 weeks. Dryness of morning mucous membranes is frequent and tends to persist. The noise of the equipment initially caused discomfort, especially to the companions. Episodes of nasal congestion and morning eye redness were associated with poor fastening of the mask. 38% did not complete correctly, with few hours of use. Four patients rejected the treatment.
DISCUSSION: Nasal CPAP involves initial complications to be detected early, because although most are sporadic or brief problems, they persist in some patients and can cause a poor treatment completion. After two months with complications, it is recommended assessing the change of masks or using humidifiers. From the sleep units, it is necessary to warn the patient of these complications and their normal disappearance.
