Throughout this stage, monitor the BP monitor for the SP’s heart rate. Watch the
continuum bar to confirm that the SP’s heart rate is below 85 percent of PMHR. If the SP’s heart rate is above the 85 percent range, determine if the SP is OK by
observing his or her color, breathing, and gait for signs of severe fatigue and ask how
he or she is doing. Ask for the RPE. You do not have to record the RPE unless it is at the end of the
stage. If the SP looks OK, does not ask to stop, and RPE is not greater than 17,
continue with the test.
