Conclusions NPPV should be the first line intervention in addition to usual medical care to manage respiratory failure secondary to an acute exacerbation of chronic obstructive pulmonary disease in all suitable patients.
NPPV should be tried early in the course of respiratory failure and before severe acidosis,
to reduce mortality, avoid endotracheal intubation, and decrease treatment failure.
NPPV = noninvasive positive pressure ventilation

If the targeted physiological parameter (PaCO2) remains unaffected by the specific treatment modality (long-term NPPV)…
If artificial ventilation does not improve alveolar ventilation …
How can we expect an improved outcome?
