Chronic obstructive pulmonary disease (COPD) causes changes in sleep quality with accompanied nocturnal drops in oxygen saturation leading to cardiac dysrhythmias, pulmonary hypertension, and more arousal. However, this sleep disturbance is an aspect of COPD that is still under evaluation. Therefore, this work is designed to detect sleep quality with type and frequency of sleep-related breathing disorders in stable COPD patients. This is a cross-sectional study that included 60 stable COPD patients. Full night polysomnographies were performed to all patients with assessment of their sleep quality and presence of sleep-disordered breathing. The studied patients were classified into two groups: group I (COPD with good sleep quality) and group II (COPD with poor sleep quality). The results revealed that the more severe the COPD degree, the worse the sleep quality parameters represented by sleep latency, sleep efficiency, and arousal index with a significant statistical difference (P < 0.05). Furthermore, a highly significant statistical difference was noticed regarding time spent in REM sleep among poor sleep quality patients with different grades of severity (P = 0.003). Additionally, obstructive sleep apnea hypopnea syndrome was the most frequent sleep-disordered breathing (65%), followed by nocturnal oxygen desaturation (17%) among poor quality sleeper. Abnormal sleep quality is more common in moderate and severe COPD patients. Obstructive sleep apnea is the most frequent sleep-related breathing disorders among COPD patients. Increased BMI%, higher Berlin scores, and lower values of PaO2 and FOSQ-10 scores are strong predictors of poor sleep quality among COPD patients.

埃及Zagazig大学医院稳定的慢性阻塞性肺疾病患者的睡眠质量

慢性阻塞性肺疾病（COPD）会导致睡眠质量发生变化，并伴随夜间血氧饱和度下降，从而导致心律不齐，肺动脉高压并引起更多觉醒。然而，这种睡眠障碍是COPD的一个方面，仍在评估中。因此，这项工作旨在检测稳定COPD患者中与睡眠相关的呼吸障碍的类型和频率的睡眠质量。这是一项横断面研究，纳入了60位稳定的COPD患者。对所有患者进行整夜的多导睡眠监测，以评估他们的睡眠质量和睡眠呼吸障碍的存在。研究的患者分为两组：第一组（睡眠质量良好的COPD）和第二组（睡眠质量差的COPD）。结果显示，COPD程度越严重，睡眠潜伏期，睡眠效率和唤醒指数所代表的睡眠质量参数越差，差异有统计学意义（P <0.05）。此外，在严重程度不同的睡眠质量较差的患者中，关于REM睡眠的时间存在高度统计学差异（P = 0.003）。此外，阻塞性睡眠呼吸暂停低通气综合征是睡眠质量最差的呼吸频率最高的呼吸（65％），其次是睡眠质量较差的睡眠者夜间氧饱和度下降（17％）。中度和重度COPD患者的睡眠质量异常更为常见。阻塞性睡眠呼吸暂停是COPD患者中最常见的与睡眠有关的呼吸障碍。BMI％升高，柏林得分更高，PaO2和FOSQ-10得分更低，这是COPD患者睡眠质量差的有力预测指标。
