At the Center for Sleep Medicine, we are experts in home sleep testing.  This technology allows us to test for sleep apnea in the home setting which is more comfortable for most patients.

The equipment we currently use is the Apnea Link Air (manufactured by Resmed).  We have chosen this as it is convenient, easy to use, has a low rate of test failure, and is comfortable for most patients.

Below, you will find tips for a successful home sleep test, as well as links to the video and instructions on how to use the testing equipment.

Tips for our patients:

Nasal Cannula

  • Position the nasal cannula so most of the plastic is in the nostrils (however it does not need to be pushed all the way up in the nose). The curved side should point towards the back of the nose.
  • Use supplied paper tape to secure it on the face so that it doesn’t move.

Oximeter (Finger Probe)

  • Make sure that the finger used for the oxygen probe does not have nail polish, artificial nails, gels, or acrylics. These will result in inaccurate oxygen readings or test failure.  (usually the index finger is used)
  • If the finger sensor is uncomfortable, you can move it to a different finger or your other hand. The white wire should be on the tip of the hand
  • Use the paper tape supplied to secure the finger sensor to the hand. (This increases the accuracy of the test)


  • Check that the device is secure and is positioned over the center of the chest
  • Make sure the belt is as snug as you can tolerate, worn over your clothing. If it is too loose, it will not produce accurate readings

If you have any problems with the test, please call us the next business day (M-F). There are instances where the test may indicate a red light in the test complete area the next morning.  This does not always mean that the test was a failure.  If you were not aware of problems during the night, when you return it we often can analyze it quickly to see if there is enough information from the recording to review.
