About Sleep Apnea
?What is sleep apnea?
Sleep apnea is a condition where your breathing repeatedly stops and starts during sleep. The most common type, obstructive sleep apnea, occurs when the muscles in your throat relax and block your airway. This can happen dozens or even hundreds of times per night.
?What are the symptoms of sleep apnea?
Common symptoms include loud snoring, gasping or choking during sleep, waking up with a dry mouth or headache, excessive daytime sleepiness, difficulty concentrating, and irritability. Your bed partner may notice you stop breathing during sleep.
?Is sleep apnea serious?
Yes, untreated sleep apnea can have serious health consequences including increased risk of heart disease, stroke, high blood pressure, type 2 diabetes, and accidents due to daytime drowsiness. The good news is that it's very treatable.
?Who is at risk for sleep apnea?
Risk factors include being overweight, having a large neck circumference, being male (though women can have it too), being over 40, having a family history, and certain physical characteristics like a small jaw or large tonsils.
About Your Sleep Test
?How does the home sleep test work?
You'll wear a small, comfortable device on your wrist for three consecutive nights while sleeping at home. The device monitors your blood oxygen levels and heart rate. The data automatically syncs to your smartphone app and is analyzed by AI and reviewed by a sleep specialist.
?Why is it 3 nights instead of 1?
Sleep apnea severity can vary from night to night. Testing over three nights gives us a more accurate picture of your typical sleep patterns and reduces the chance of missing a diagnosis or over/underestimating severity.
?Is the device uncomfortable?
The Celeste+ device is designed to be comfortable. It's a small, lightweight wrist-worn monitor similar to a fitness watch. Most patients report that they forget they're wearing it after the first night.
?Can I sleep in any position?
Yes! Sleep however you're comfortable. The device works in any sleeping position. In fact, sleeping in your normal position gives the most accurate results.
?What if I don't sleep well during the test?
That's actually okay. The test is designed to capture how you actually sleep, not ideal sleep. Even partial nights provide useful data. If you have significant trouble, the test can be repeated at no additional charge.
?Do I need to change my medications?
In most cases, you should continue your regular medications. However, talk to your doctor if you take sleep aids or sedatives, as they may want to adjust the timing during the study.
Getting Your Results
?How long until I get my results?
Results are typically available within 48-72 hours after you complete your final night of testing and the data syncs. Your doctor's office will contact you to discuss the findings.
?What does my AHI score mean?
AHI (Apnea-Hypopnea Index) measures how many times per hour your breathing stops or becomes shallow. Less than 5 is normal, 5-15 is mild, 15-30 is moderate, and over 30 is severe sleep apnea.
?What if my results are normal?
Normal results mean you likely don't have significant obstructive sleep apnea. Your doctor may discuss other potential causes for your symptoms or recommend lifestyle modifications.
?What if I'm diagnosed with sleep apnea?
A diagnosis is actually good news—it means we've identified a treatable cause for your symptoms. Your doctor will discuss treatment options, most commonly CPAP therapy, which is highly effective.
Treatment & CPAP
?What is CPAP therapy?
CPAP (Continuous Positive Airway Pressure) is the most common and effective treatment for sleep apnea. A machine delivers a gentle stream of pressurized air through a mask to keep your airway open during sleep.
?Is CPAP the only treatment option?
While CPAP is the most common treatment, other options include dental appliances (for mild to moderate cases), positional therapy, weight loss, and in some cases surgery. Your doctor will recommend what's best for your situation.
?Will I have to use CPAP forever?
For most people, CPAP is a long-term treatment. However, significant weight loss can sometimes reduce or eliminate sleep apnea. Your doctor will monitor your progress and adjust treatment as needed.
?How long does it take to get used to CPAP?
Most people adjust to CPAP within 2-4 weeks. The first few nights may feel unusual, but consistent use leads to comfort. Many patients feel significantly better within days of starting treatment.
?Can I travel with CPAP?
Yes! CPAP machines are portable and approved for air travel. Most airlines allow them as medical devices that don't count against your carry-on limit. Travel-sized machines are also available.
Practical Questions
?How do I return the testing device?
If the device was shipped to you, use the prepaid return label included in your package—just drop it in any mailbox. If you picked it up from your doctor's office, return it there at your next visit or as instructed.
?Will insurance cover my test?
Most insurance plans cover home sleep testing. Your doctor's office handles the insurance billing. Contact your insurance company or ask your doctor's office if you have questions about coverage.
?What if I have trouble with the device?
The Celeste+ app includes troubleshooting tips. For additional help, our support team is available by phone during business hours. Most issues can be resolved quickly.
?Can I do the test if I work night shifts?
Yes, the test works during whatever time you normally sleep. Just wear the device during your main sleep period, whether that's during the day or night.
?What if I need to skip a night?
Try to complete three consecutive nights for the best results. If you must skip a night, continue the following night. The test requires at least two valid nights of data.
