慢性阻塞性肺疾病(COPD)是一种常见的进行性呼吸系统疾病,对其进行监测措施这对急性期的抢救,缓解期的治疗及其预后的判断都有重要的临床意义,也有利于提高重症患者的生存率和生活质量。这种病越来越引起临床工作者的重视。COPD患者常于夜间病情加重,伴以夜间低氧血症,一般伴夜间低氧血症者比无夜间低氧血症者预后差。最近发现在呼吸睡眠暂停综合征(SAS)中COPD的发病率高于正常人,故对COPD患者进行呼吸和血氧监测以了解其夜间血氧的变化是十分重要的。
Chronic Obstructive Pulmonary Disease (COPD) is a common progressive respiratory disease and its monitoring measures have important clinical significance for the rescue of acute phase, the treatment of remission and the prognosis of the disease. Improve the survival rate of critically ill patients and quality of life. This disease has drawn more and more attention from clinicians. COPD patients often aggravate their symptoms at night, accompanied by nocturnal hypoxemia, usually with nocturnal hypoxemia than those without nocturnal hypoxemia poor prognosis. Recently, it has been found that the incidence of COPD is higher in patients with sleep apnea syndrome (SAS) than in normal people. Therefore, it is very important to monitor the changes of respiratory rate and blood oxygenation in patients with COPD to understand the changes of nighttime oxygen demand.
