The ‘Change Protocol’ button is used to increase or decrease the predetermined protocol.

This button can only be used during the Warm-up stage.

4.5.1.7 Go To Recovery Button

The ‘Go to Recovery’ button is used to stop the exercise test at any point and go directly to

Recovery. The SP will continue through the Recovery Stages but will not complete the remainder of time

in the exercise stages.

4.5.1.8 Show Data Button

The ‘Show Data’ button is used to look at the heart rate and blood pressure from the

4.5.1.9 Estimated VO 2 Max Field

The ‘Estimated VO 2 max’ field is used to view this variable after the treadmill test is

completed. The VO 2 max is calculated and displayed after Recovery 2 has been completed.

4.5.1.10 Continuum Bar

The continuum bar has the predicted maximal heart rate (PMHR) in beats per minute on the

top and the percent of the maximum heart rate (%HR) along the bottom.

„ During Warm-up, the SP’s heart rate should increase to approximately 60 percent of

the maximum heart rate. This range is displayed on the continuum bar. If the heart rate

goes higher than this, the protocol should be decreased for Stages 1 and 2.

„ During Stage 1, the SP’s heart rate should be about 60-80 percent of the maximum

heart rate. When the ISIS system changes to Stage 1, the continuum changes to reflect
