4.6.3 Increasing the Exercise Protocol
Exhibit 4-56. Increasing the exercise protocol The method for increasing the protocol is similar to decreasing the protocol. If the
heart rate is less than 50 percent during Warm-up, you should increase the protocol for
the remainder of the exam. Click ‘Change Protocol’ button. Click the up arrow to increase the protocol. Click
Apply. The ISIS system will give an auditory message:“At the beginning of the next stage, change treadmill controller to the next higher
protocol.” When the Warm-up is finished, the ISIS system will advance to Stage 1 and will
automatically select the next higher protocol. This protocol will be highlighted in red
below Stage 1. The same protocol will be used for Stage 2. In contrast, the treadmill controller does not move to the next higher protocol
automatically even though ISIS was changed. Press ‘Next Stage’ on the treadmill
controller to advance to Stage 1 on the next higher protocol. When the protocol changes to Stage 2, the treadmill controller will now go
automatically to Stage 2 of the current protocol (the higher protocol).
