It may happen that you want to create a non-existent patient file.  This may be to play or exercice with Audiqueen, to give a demonstraion, to execute a study or for any other reason. 

Suppose you generate an audiogram in this patient.  If ever you run Analytics, this result may appear in the test results.  This of course should be avoided.  

The solution is to mark this patient as dummy.  You can do this in the Patient Information window.
