Measuring System, Computer Program, Set of a Measuring Device and a Computer Program and Method for Operating the Measuring System

A software program comprising program code means for performing the following steps when said program is run on a microprocessor,

• receiving data measured by a measuring device, said data representing at least one of the volume flow expired and the volume flow inspired by a user;
• generating at least one of an expiration flow profile and an inspiration flow profile on the basis of said data;
• storing said profile on a memory storage;
• wherein the software program comprises further program code means for performing the step of displaying a representation of at least two flow profiles, which allows a comparison of the profiles, on display means being connected with the microprocessor, and further program code means for performing the step of selecting at least one of an expiration flow profile and inspiration flow profile as a reference flow profile and storing it in a memory.

A method for operating a measuring system, comprising the steps of

• continuously monitoring the flow of air streaming through a section of the device when the user is at least one of expiring and inspiring, thereby generating data of at least one of an expiration volume flow profile and an inspiration volume flow profile,
• storing data of at least one measured volume flow profile in at least one memory section and
• selecting a reference flow profile from measured volume data and
• storing a reference flow profile in a first memory section and
• displaying a representation of a reference flow profile and the at least one measured flow profile, which allows a comparison of the profiles.
