It is based on the latest scientific evidence and replaces the previous guideline from 2017. This revised guideline provides detailed recommendations on the application of non-invasive ventilation, ventilation settings, and the subsequent follow-up of treatment. In addition to the updated evidence, important new features of this guideline include new recommendations on patient care and numerous detailed treatment pathways that make the guideline more user-friendly.
