In many ICU's in these days non-invasive mask ventilation is a technique in addition to the traditional invasive ventilation via endotracheal tube if the patient is able to cooperate. If contraindication (mucus retention, swallowing disorders, acute neurologic disorders, circulatory instability) and definition of interruption criteria are regarded, the method is safe. ⋯ According to pathophysiologic pathways the use of non-invasive techniques seems limited to not-so-advanced stages of the disease in these cases. Considering the growing importance of this technique for the weaning procedure after long-term mechanical ventilation should be established at every ICU.
