Inhalation Therapy in Ambulant and Hospitalized Patient Using Available Film Sequences From the Internet

"After written consent patients will be asked whether they know how to use the inhalator and for how long therapy has been already conducted. Patients using the inhalator correctly have completed the study at this point. If patients have demonstrated incorrect use of the inhalator, a film sequence with instructions will be shown via a tablet. The learning success will be assessed subsequently. When patients show correct application, they will be asked to come back for a follow-up visit within 2 to 8 weeks, otherwise they will be retrained by study staff. At the follow-up visit another demonstration evaluation will be performed.~While demonstrating patients will use the inhalator without any drug that could have any medicinal effect on them."
