Chronic Obstructive Pulmonary Disease (COPD) is a worldwide common disease with high morbidity and mortality and leads to heavy social and economic burden. Health management of stable COPD patients has been suggested to be essential for delaying diseases progress, reducing acute exacerbation events and improving patient quality of life. Non-invasive ventilation (NIV) is a widely used treatment in COPD patients. There were studies shown that NIV could improve ventilation, blood gases etc., and several clinical trials have shown improvements in survival, exercise capacity, quality of life and so on. Compliance to NIV and optimal parameter setting are important factors that will affect the effect of the use of NIV, thus NIV usage monitoring might also be a crucial element in the health management of COPD patients. Many studies have been designed to study the effect of tele-monitoring program on the management of COPD patients. However, almost none of these studies were designed for specific population, and little is known about the effect of such program on the management of patients with NIV treatment.
