Display device and method for displaying

The present invention provides a device for displaying respiratory conditions of a subject on a monitor having a first parameter acquisition unit (11) for acquiring a first respiration parameter representing a respiratory condition of the subject; a second parameter acquisition unit (12) for acquiring a second respiration parameter representing a respiratory condition of the subject, said second respiration parameter differing from said first respiration parameter; and a display controlling unit (13) for displaying, on the monitor, a chart representing a relationship between the first respiration parameter acquired by said first parameter acquisition unit and the second respiration parameter acquired by said second parameter acquisition unit; wherein the chart represents the relationship between the first respiration parameter and the second respiration parameter in each respiration cycle, and a plurality of charts for preceding respiration cycles and charts for subsequent respiration cycles are displayed so as to adjoin one another successively in a prescribed direction.
