The disclosure describes improved systems and methods for configuring the layout of a graphical display in a ventilatory system. Specifically, the present methods provide a user interface for configuring one or more layout categories associated with data on the graphical display. Upon selection of a layout category, a clinician is provided with a preview of the layout of the layout category. The preview consists of one or more parameter positions. Each parameter position is associated with a parameter. The clinician is also provided with a listing of possible parameters. The parameter positions in the preview and the possible parameters in the listing are selectable elements. Once a parameter position is selected, a possible parameter can be chosen to replace the parameter associated with the selected parameter position. If this replacement is acceptable to the clinician, the clinician can access an accept button to implement the replacement in the graphical display.
