Sleep Apnea and Sleep Study FAQs

In the past few weeks, we’ve been working on adding a Frequently Asked Questions section to our website to act as a resource for people at all stages of diagnosing and treating their sleep apnea. 

Check out our lists of Frequently Asked Questions

We’ve broken down our FAQ lists into six main topics:

  • Sleep Apnea: basics on the sleep disorder, how to recognize it, and some misconceptions
  • In-Center Sleep Studies: including how to prepare, what to bring, and when to expect results
  • Home Sleep Testing (HST): like what is a home sleep test, how you will obtain the device, and how to use the machine
  • PAP Treatment: such as how frequently to use the device and common troubleshooting
  • PAP Resupply: including why and how often you should replace your supplies
  • Insurance: such as insurance basics and what is covered by your insurance

Our Top 6 FAQs

Because there’s absolutely no room to fit all our FAQs in this post, we’ve compiled a list of our top 6 (one from each list) and a shortened response to give you an idea of what to expect (click the title for the full answer). 

1. Will my insurance cover my sleep study or PAP device? 

Most insurances (HMO, PPO and Medicare) cover sleep studies and PAP therapy for the treatment of sleep disorders. Plans may vary in their coverage and many now require authorization for these services.

We understand that patients and their physicians are concerned about rising out-of-pocket expenses for health care; unfortunately, this often affects decisions about how healthcare is administered. By contracting as an in-network provider with more payer organizations, more patients can afford to receive the proper diagnosis and treatment for their sleep disorders.

2. How long does it take to get sleep study results? 

You will typically receive your results within two weeks (10 business days). Each sleep study is scored by a technician and then reviewed by a sleep specialist. See our video for more information on what happens after your sleep study. 

3. How do I know how to use the Home Sleep Testing device?

The HST device is fairly simple to set up. This manufacturer video explains how to set up and operate the device. The morning after you schedule your appointment, you will receive an email with detailed instructions about how to self-administer the home sleep test. Plus, if you pick up the device in person, you will have a live technician walk you through how to use it. 

4. Do I have to use my PAP device every night? 

You should use the PAP machine as ordered by your physician. However, it is generally recommended that you use your PAP machine every night. If at first you experience some difficulty staying asleep with the PAP device for a long period, it is recommended that you use it every night for as long as you can. Then try adding 30 minutes – 1 hour to your usage time nightly, until you have fully adapted to the machine.

5. How often should I replace my PAP equipment? 

Certain supplies need be replaced anywhere from every two weeks to every six months. Many insurance plans follow these Medicare guidelines: 

Every Month: Nasal Mask Cushion/ Pillows (twice per month)
Full Face Mask Cushion (once per month)
Device Filter (twice per month)
Every 3 Months: Mask and headgear, tubing
Every 6 Months:Chinstrap, humidifier, water chamber

6. I think I might have sleep apnea. What should I do?

If you suspect that you may have sleep apnea, it is very important to get diagnosed so that you can begin treatment and reclaim your health. A sleep study can determine whether you are suffering from a sleep disorder. Talk to your doctor about having a sleep study, or request a study

    I used the device the first night, but the next morning only 50% of the pie lit up. I am aware that I will need to repeat the test. So my question is, do I use the same device tonight or send it back for another one?

  2. Mark Oresko Reply

    Hello, my name is Mark. I served in the USMC in 2001-2005. After my last deployment Feb 2005, I noticed that I had documented that I was getting restful sleep, I was feeling sleepy all the time, I had headaches, and would wake up gasping for air. I wasn’t diagnosed with sleep apnea until 2012. Would it be safe to say that I was experiencing initial onset symptoms of OSA while I was in service. It has been impossible for me to convince the VA that my OSA could be service related.

    I take Zopiclone (7.5mg) to sleep, as I have insomnia. I would like to stop taking it; will a sleep study give me answers on how to stop taking Zopiclone? Or will it just address sleep apnea? If I have sleep apnea and require oxygen during the night, will I still have to take Zopiclone to sleep?
