STRESS AND EXERCISE TESTING
12. It has been noted that letting the patient view the plethysmographic
waveform enables them to assist in reducing motion artifact. To test
for interference during exercise:
A. Have the patient slowly move their head from side to side.
B. Next, have the patient slowly move their head up and down.
C. The Sa02 should not fluctuate more than 1%.
D. Watch that the ear probe and cable do not move on the ear and the
cable does not tug on the probe as the patient's head moves.
13. If vigorous exercise is anticipated, have the patient quickly move
their head . Some readjustment of the cable and headband may be neces
sary to eliminate motion artifact. (See Signal and Data Validity
Section pages 32-34)
Setting up the oximeter:
Ensure that the oximeter is in the Slow Response Mode (6 second aver
age) to decrease the effect of motion artifact on the calculated
Sa02. (See Page 21)
Set the Patient Alarms at the desired limits. (See Page 24)
