Patient Perception
During programming you may wish to mark the patient’s perception levels on the CPA.
1.
The ‘Threshold’, ‘Comfort’ (C- and C+ for lower and upper bounds of Comfort), and
‘Maximum’ buttons (Figure 9.2) can be used to mark when the stimulation is first
felt by the patient, when it is comfortable and when it is very strong, respectively.
The levels will be indicated by horizontal lines on the intensity bar graph and on the
patient sensitivity graph.
2.
To change the levels, touch the button once to clear the mark, then touch again to
set the mark to the new level.
