Respiratory Support in Chronic Obstructive Pulmonary Disease (COPD) Patients After Acute Exacerbation With Monitoring the Quality of Support
The hypothesis of this study is that any of 3 modalities of home non- invasive ventilation (NIV) compared to 'no NIV' (=hospital NIV) will reduce re-admission to hospital or death in COPD patients who remain persistently hypercapnic following an exacerbation requiring NIV.
• 1\) Patients with COPD, GOLD C or D and Forced expiratory volume in one second (FEV1)\<65%;
• 2\) AHRF (pH\<7,35 and PaCO2≥45mm Hg (≥6kPa) treated more than 24h with Ventilation (non-invasive or invasive);
• 3\) 48h to 2 weeks with pH\>7.35, and PaCO2\>45 (\>6kPa) after NIV withdrawal, during daytime at rest without oxygen or ventilatory support (or with O2 if patients are not able to avoid O2 with immediate desaturation below 80%).
