Influence of different ventilation modes of non-invasive ventilation in patients with hypercapnic-hypoxic ventilation failure – iVAPS vs. ST

Introduction COPD is one of the leading causes of death worldwide. Patients may develop hypercapnic-hypoxic respiratory failure with respiratory acidosis as the disease progresses at an advanced stage. One of the therapeutic approaches at this stage, in addition to noxious avoidance, breathing training and guideline-based drug therapy, is the initiation of non-invasive ventilation. Therefore, with this study, we address the question of whether a modern beaming mode "iVAPS" has an advantage over a conventional mode "ST".
