Patients suffering chronic hypercapnic respiratory insufficiency (e.g. in chronic obstructive pulmonary disease, obesity hypoventilation syndrome) benefit from home mechanical ventilation. These patients are complex; and the ventilator´s parameters should be set-up according to the underlying disease and particular patient's characteristics. The non-invasive ventilation therapy is mostly titrated while the patient is awake, hence Problems, such as Patient-Ventilator asynchrony, arising while sleeping on the ventilator therapy would remain undetected. Sleep studies, such as polysomnography or polygraphy and transcutaneous carbon dioxide monitoring could be valuable tools to fine-tune the ventilator's settings. This could foster the ventilator´s effectivity and patient satisfaction, thus therapy's adherence. Nevertheless the sleep studies are expensive, time-consuming and not widely available. The aim of this study is to learn the findings of sleep studies when they are performed on stable patients on home mechanical ventilation as part of their routine check-ups. In this context, it will be assessed whether the sleep studies' findings lead to a change (adjustment) of the ventilator´s therapy. Moreover, this study aims to investigate whether the absence of sleep studies would result in missing important events that require an adjustment of therapy. The results of this study could provide information that lead to a more standardized protocol of follow-up checks of patients on home mechanical ventilation in a cost-effective manner.

Primary | Adjustment of non-invasive ventilation | Each case will be evaluated separately by 2 investigators. One of them will be provided with the diurnal evaluations only (as routinely); the second investigator will additionally have access to the sleep studies. Each investigator will classify the case as one of the following labels (primary outcome):
Non-invasive ventilation therapy optimization is not required (all ventilator's parameters should stay unchanged) Optimization of non-invasive ventilation therapy is required (one or more of the ventilator's parameters should be re-set, irrespective of the magnitude) |
One day | |
Secondary | Non-invasive ventilation compliance | The ventilator's optimization will be performed randomly according to the clinical-based approach or the sleep studies-based approach. In the next follow-up visit, both arms will be re-evaluated. The change in non-invasive ventilation therapy compliance will be explored based on the ventilatorĀ“s built-in software data. | 6 months | |
Secondary | Health-related quality of life: questionnaire | In the next follow-up visit, the health-related quality of life of both groups will be evaluated with the severe respiratory insufficiency questionnaire. | 6 months | |
Secondary | arterial level of carbon dioxide | In the next follow-up visit, the arterial level of carbon dioxide of both groups will be evaluated in the blood gas analysis | 6 months |
