What to Expect During a Sleep Test (Polysomnogram)
Mercy offers two sleep disorders testing centers for your convenience — one at our main campus in Canton, Ohio, and one at the Mercy Health Center of Jackson in Massillon.
Our sleep testing usually involves an overnight stay in our sleep lab, where you’ll have your own private room, including a TV, free Wi-Fi, and a private bathroom with shower. Much like what you would expect at a hotel, our (See more pictures of our sleep labs below.)
Most sleep tests last from 8:30 pm to 7 am. However, times can vary based on your specific needs. After you arrive at our sleep lab, a certified sleep technologist will affix sensors, or electrodes, to your scalp, face, chest, arms, legs and a finger. This will enable the technologist to monitor your body’s internal activities as you sleep.
What to Do on the Day of Your Study
On the day of your study, you should continue your normal activities, including taking any prescibed medications unless a physician tells you otherwise. However, you should not nap or consume any caffeine after noon.
What to Bring to Your Sleep Study
We recommend that you bring a two-piece set of pajamas or something else you will feel comfortable sleeping in. You should also pack:
- Any medications you already take at night or in the morning
- Any sleep aids you currently take
Oxygen is available at our sleep labs, if needed.
CPAP Sleep Study
If you are diagnosed with obstructive sleep apnea (OSA), the first line of highly effective treatment is a CPAP (continuous positive airway pressure) machine. To prevent the airway collapse that occurs with OSA, the CPAP’s positive air pressure acts as a splint, keeping your airway open.
Before you receive your own CPAP machine, an overnight CPAP sleep study may be ordered by your physician. As with diagnostic sleep testing, you will be hooked up to electrodes during the CPAP study. The only difference is that you will also wear a CPAP mask. Our technologist will remotely adjust the pressure to eliminate snoring and apnea events.
Based on the CPAP study results, your physician will prescribe the machine and the pressure level that’s most appropriate for you. All CPAP machines must be ordered from a durable medical equipment company of your choice with a physician order.
Your CPAP Machine and Mask at Home
There are several types of CPAP masks. All are effective in treating OSA. Types you can choose include full-face masks, partial masks that cover just the nose, and tubes that go into the nostrils. You can change the type of mask you use after treatment begins. They should be replaced frequently.
Side effects many include nasal congestion, dryness and mask discomfort. However, these issues are easily corrected. Often, an adjustment of the machine’s humidifier or a different type of mask is all that is needed.
Follow-up is very important. Most insurance companies, Medicare and Medicaid require follow-up with your physician 31-90 days after treatment begins and yearly after that. Keeping these appointments is often necessary for insurance coverage of the machine.
Our sleep center rooms are designed to be comfortable so that you can relax and fall asleep.
Each sleep testing room comes with a private bathroom and shower.
Mercy Sleep Labs are equipped with the latest technology for sleep monitoring and testing.
Your entire sleep study will be monitored by a registered sleep technician and reviewed and interpreted by a board-certified sleep physician.
