Let me start off by saying I have little knowledge when it comes to COPD (excuse me if I use the wrong terminology). I work as a game designer at SilverFit located in the Netherlands. My current project is about creating a visualization to make monitoring and management of COPD easier and (most of all) less boring.

We are using a spirometer for the visualization and because I currently lack the knowledge of spirometry use, I would like to get some more information on the subject. You would help a great deal if you could share your view on the following questions:

• Where and when do you use a spirometer?
• How often and how long do you use it?
• And most important: what are your experiences with it?
