Acute exacerbation of COPD (AECOPD) worsen prognosis and quality of life of COPD patients. Telemonitoring could be a useful tool for early identification of AECOPD. Parameters that have to be monitored are not well defined.
Patients with severe COPD may use home non-invasive ventilation (NIV). NIV have built-in software which are recording the breathing pattern of patients when used. The aim of this study is to identify ventilation parameters that are modified at the early stage of an AECOPD.
