Disclosed is a medical device including a display (160) for providing feedback to a rescuer (120) who is performing Cardio Pulmonary Resuscitation (CPR) chest compressions to a patient (130). The display (160) is structured to graphically indicate an instantaneous value of a measured compression depth of the chest of the patient (130). The display (160) includes an indicator range (170) that corresponds at least in part to a compression depth range of some of the measured compression depths and an indicator (162) represented as progressing along the indicator range (170) as the depth changes within the compression depth range (170) to represent a value of the measured compression depth in relation to the indicator range (170). When the measured compression depth is passing a first point (demarcating first portion of indicator range 172) of the compression depth range (170), the indicator (162) progresses at a first rate relative to a first difference in the measured compression depth, and when the measured compression depth is passing a second point of the compression depth range (170) that is distinct from the first point, the indicator (162) progresses at a second rate that is different from the first rate relative to the first difference in the measured compression depth.
