Patient information sheet
Condition
Chronic obstructive pulmonary disease (COPD)
Intervention
There are two groups: the first will receive either auto variable positive airway pressure ventilation (auto VPAP) and the second group will receive standard non-invasive positive pressure ventilation (NIPPV). After eight weeks the two groups will cross over. The patients will be randomised to start on either auto VPAP or NIPPV. The control group is the group receiving standard NIPPV.
