this change. If the SP’s HR is above 80 percent of PMHR at any time in Stage 1,

determine if the SP is OK by observing color, breathing, and gait for signs of severe

fatigue and ask the SP how he or she is feeling.

„ During Stage 2, the SP’s heart rate should be below 85 percent of the predicted

maximal heart rate (90% for SPs 12 through 1 8 years). The continuum changes to

reflect these numbers. The ISIS system will display 85 percent or 90 percent based on

the age of the SP. If the SPs HR is above these criteria at any time in Stage 2,

determine if the SP is OK by observing signs and symptoms as described for Stage 1.

„ During Recovery, the SP’s heart rate is expected to decrease back to approximately

110 beats per minute or less. The continuum changes to reflect the 50 percent PMHR.

This is used as a guideline.
