Primary objective
ARF
ARF, PRESSURE SORE
To determine if a protocolized rotational use of interfaces during NIV compared to the standard of care is effective in reducing the development of new pressure sores in patients with hypercapnic ARF treated continuously (> 24 h) with NIV administered (i) to avoid intubation (ii) as an alternative to invasive ventilation, (iii) to avoid reintubation after early extubation, or (iv) to prevent reintubation.
