Due to irreversible dilation of the bronchi, the presence of secretions and airflow obstruction, subjects with bronchiectasis may be predisposed to hypoxemia during sleep or symptoms that might lead to arousal. Therefore, the objective of this study is to describe these subjects sleep through the complete nocturnal sleep study (polysomnography). An observational study was carried out involving the evaluation of 21 patients with bronchiectasis at the Sleep Laboratory of the Master s and Doctoral Program in Rehabilitation Sciences of the Universidade Nove de Julho in the city of Sao Paulo, Brazil. Mean age was 51.6 ± 15.1 years; 57.1% of the patients were female and mean body mass index was 23.9 ± 3.7 kg/m2. Mean income was 1.3 times the minimum wage and only 28.6% had completed high school. The median Epworth Scale score was 7.5 (0-23). A high risk for the obstructive sleep apnea (OSA) syndrome was found in 38.1% of the subjects and there was a predominance of obstructive lung disease. Mean total sleep time was 282.7 ± 69.5 min, with sleep efficiency of 79.2 ± 29.2%. Stages 1 and 2 were altered and the mean sleep apnea and hypopnea index was 3.7 ± 4.9 events/hour. The number of arousals was 5.6 ± 2.9/h. The oxyhemoglobin desaturation index was 5.9 ± 8.9/h and minimum oxyhemoglobin saturation was 84.5 ± 5.8%. Patients with bronchiectasis had a low risk of OSA, presence of excessive daytime sleepiness and changes in sleep quality.
