My at-home sleep study felt like a cross between science fair and slapstick. Step one, wrap an overly friendly strap around my torso. Step two, clip a pulse ox to my finger like a tiny koala that refuses to let go. Step three, feed a plastic tube to my nose, hook everything up, and pretend this is normal! I usually rotate between both sides and my back when I “sleep,” but with all the wires and straps I turned into a back-only sleeper who dared not twitch, lest I foul up the data gathering and render my test results unusable!
By morning, my home sleep apnea test had a collected all of the data necessary to render my final verdict, moderate obstructive sleep apnea. It wasn’t until a few days after my experience, though, that those results actually showed up in my online medical chart: an average of 22 (stopping!) breathing events per hour and a blood oxygen saturation low point of 71 percent. Yikes!
If you are wondering what you might expect in your home sleep study experience, keep reading. I’ll discuss the gear, the quirks, and how my at-home sleep study felt in real life to help give you an idea how a home sleep apnea test might play out for you.
What To Expect In An At-Home Sleep Study – Feel Prepared Before Test Night
If you like surprises, a home sleep study is probably not the place to get them. Here is what showed up in my kit and how it felt to use it in the real world. This might vary slightly from provider to provider, but hopefully my experience will help you know more about what to expect in your own home sleep study.
- Torso respiratory belt, a snug band around chest or abdomen that tracks breathing effort. This belt is attached to the data collecting device, which rests somewhat uncomfortably on your chest all night and hooks up to the next two items. Imagine a hug from a polite robot, firm enough to collect data, but not quite spa-like.
- Finger pulse oximeter, a clip that logs oxygen saturation and heart rate. I also used a little bit of tape to make sure it stayed on my finger during my rough-and-tumble night. It blinks now and then, which is fun until you remember it is watching your every breath like a very small lighthouse.
- Nasal cannula, slim plastic tubing that senses airflow through the nose. This is the same type of tubing you’d get oxygen through if you were at the hospital, basically just used in reverse to sense your breathing. Placement is simple (a little gentle taping to the face helps keep this from popping out during the night), sleeping with it is the challenge, the tubing loves to remind you it exists the moment you roll.
These parts are standard issue for home sleep apnea testing ordered by a clinician, they capture breathing effort, airflow, and oxygen levels without a full lab visit. Always discuss your best options with your physician. You can also reference the American Academy of Sleep Medicine position statement on HSAT for when home testing is appropriate, AASM HSAT overview.
Why Position Matters In A Home Sleep Apnea Test – Reduce Surprises From Back Only Sleep
During my at-home sleep study, the gear (not so gently!) nudged me into back sleeping for most of the night. That is important because many people have position dependent obstructive sleep apnea. Event counts often climb when you lie on your back. If your study turns you into a statue, tell your doctor, that context helps them read your results and consider positional strategies later in the context of a home sleep apnea test. For background on position dependent OSA and therapy ideas, see this review POSA overview and this summary of positional therapy options positional therapy.
My Results And What They Mean Translate Numbers Into Plain English
On paper my at-home sleep study night looked like a busy highway.
- AHI (Apnea–Hypopnea Index) 22 per hour, that sits in the moderate category for adults, learn more from the Cleveland Clinic here – Apnea–Hypopnea Index.
- Lowest SpO₂ 71 percent, far below the usual overnight range, see typical oxygen level guidance from Cleveland Clinic, blood oxygen levels.
The numbers explain the never-ending groggy mornings and why my partner keeps asking if we own a chainsaw and kept it running in the bedroom. And as noted above, if your at-home sleep study forced you into one sleeping position, note it for your follow up. Sleep position can tug those numbers up or down in any home sleep study.
Treatments My Doctor Offered – Choose A Path That Fits Your Life
After my at-home sleep study results were analyzed by my doctor, he walked me through two main options, CPAP and mandibular advancement devices. While he was keen to push a CPAP machine on me at the beginning, he also acknowledged that the MAD (Mandibular Advancement Device) option was a good choice for many people, and often works for people in the “moderate” sleep apnea range and for people who just can’t tolerate a CPAP. Everyone is different, talk to your own doctor about the best plan for you.
CPAP – What It Is And How It Works
Continuous positive airway pressure uses gentle airflow through a mask to hold the airway open during sleep. It is first line for many with moderate to severe OSA and is well studied for reducing sleepiness and improving quality of life, with potential cardiovascular benefits in the right patients, see the AASM CPAP fact sheet.
Mandibular Advancement Devices (MADs) – The Over The Counter Route I Am Trying First
MADs are mouthguard style devices that bring the lower jaw slightly forward to help keep the airway from collapsing. I am using an over the counter model, not a custom dental device, on my doctor’s advice that OTC options can work well for many people. Guidelines support oral appliances for primary snoring and for mild to moderate OSA when clinically appropriate, see the joint guideline, AASM and AADSM oral appliance guideline. Always decide with your clinician.
Practical Tips – Simple Ways To Make An At Home Sleep Study Easier
- Practice with the gear – Wear it for 20 to 30 minutes before lights out so the first hour of your at-home sleep study is not a complete three-ring circus.
- Note your sleep position – If you ended up on your back all night during your at-home sleep study, include that detail in your follow up.
- Tidy the bedside – Clear cord paths, add a hand towel for nasal condensation, and keep tape nearby in case a sensor loosens on your at-home sleep study night.
- Expect a weird start, but try to relax – Most people tend to relax after the novelty wears off a bit – I certainly did. Relaxing helps you sleep and your home sleep apnea test data quality can be more accurate if you’re not fighting the machinery all night.

A Little Humor Helps – Because Laughing Beats Fighting Your Tubing
Sleeping in a nest of medical sensors forced me to exercise patience and posture, and also taught me that my nose is stronger than I thought. At 2 a.m. I was doing breath math and wondering if I had invented a new kind of apnea by panicking, but in the morning it was all over. While it wasn’t the most comfortable experience ever, it really was pretty low-impact and provided the critical information I needed to move forward into a healthier (and hopefully longer!) future. If your partner tells you that you snore, or if you have any reason to suspect you might suffer from obstructive sleep apnea, consult with your physician – your life may literally depend on it!
