Performing a Home Study

1. Measure Head Size

  • Using a measuring tape, measure the circumference of the head, pulling the tape tight beginning in the center of the forehead.
  • Long hair should be put up while measuring to get a more accurate reading. The hair should be worn up during the study also, preventing the strap from slipping during the night.

2. Determining Strap Setting

Head Size Strap Settings
< 21.5” 0
21.5” 1
22.0” 3
22.5” 5
23.0” 7
23.5” 9
≥ 24.0” 10

3. Adjust Strap Setting

  • Adjust the strap to the appropriate setting and the setting number visible in the U shape notch on the top side of the strap.

4. Show Patient How to Apply the ARES at Home:

  • Thoroughly wash and dry your forehead.
  • Remove the plastic covers from the electrodes.
  • Place the ARES forehead sensor on the center of your forehead and gently pull the black strap to the back of your head.
  • Remover hair from under the sensor.
  • Adjust the slip tube to tighten the cannula. Make sure the cannula tips cannot be pulled more than ¼ inch away from the nose.
