While artificial respiration was rarely used in the early days of modern medicine, today it is one of the essential therapy methods in everyday hospital life and has gained particular importance in recent years. Non-invasive ventilation masks provide an interface between human and machine in non-invasive ventilation. In a strictly regulated field such as medical technology, development periods are often long and impacted by technical requirements, whereas design can add significant value as an empathic and human-centred profession. Driven by this, the project focus was not only on technical requirements and efficient patient care, but also on intuitive handling by the user and the patient's well-being. To ensure a high level of comfort while also providing effective therapy, particular attention was paid to the ergonomics of different facial types.
