How Often Should You Be Tested For Sleep Apnea

If you have been on CPAP treatment for a year or more you have probably started wondering 'how often should you be tested for sleep apnea?'  Because we are all different, there isn’t a set answer but there are signs to look out for that will help indicate when it is time for you to do a new sleep study.  For many patients, it will depend on your doctor’s preferences as to when you should retest.  Some physicians may require an annual test, and others may prefer a test every five years.

One of the signs that you may need to retest is the return of your sleep apnea symptoms.  If your symptoms return, first check out your supplies to make sure they are up to date.  An old mask may be leaking, and a large leak can result in your PAP therapy not working as well as it should.  If you find that you have old supplies, visit to get a new mask and PAP supplies. has a user friendly guide to help remind you how often to replace your supplies, check it out to see if you are eligible.  If you find that your supplies are new and are not leaking, speak with your physician about getting a sleep test done to ensure that your PAP is working properly for you.

Another reason to be tested again for sleep apnea is a major lifestyle change or a change in health.  If you have lost or gained a significant amount of weight, it may be that your current pressure needs to be adjusted to work better for you.  An easy at-home sleep test will determine if your Apnea-Hypopnia Index, or AHI has increased, or if it is being maintained on your current pressure.   If your AHI is not being controlled, your physician can order a new in-lab sleep study or do an in-home re-titration to determine what pressure your CPAP machine should be set to.  Patients who use an automatic CPAP or “APAP” will not run into the same issues as those with set pressure machines.  The APAP is self-adjusting on a nightly basis, so it will keep up with any life-style changes.  Your doctor may still recommend regular testing if you are on an APAP, but it may not be as frequent.  If you are a PAP user interested in getting an automatic PAP device, check out our selection of APAPs.
