Singular Sleep is an online sleep center that offers all the products and services that you need to remotely diagnose and treat sleep apnea.

In order to offer you the very best value, we do not deal with healthcare insurance companies directly. This allows us to save a great deal on overhead and administrative expenses that have nothing to do with your health and pass along the savings to you. We are considered an "out-of-network" provider to commercial insurance plans like Blue Cross Blue Shield, Aetna, Cigna, and United. We are happy to provide you with a "superbill" for purchased medical products and services that you may submit to your insurer for reimbursement.

We currently accept all major credit cards, HSA or FSA cards,  as well as the following payment options: Shop Pay, PayPal, Google Pay, MetaPay, and Venmo.

We also offer payment plans such as Affirm and PayPal Credit for product orders such as CPAP equipment. For additional information on our financing options, please visit https://www.singularsleep.com/pages/financing-options.

Of course! Please drop us a line here or call us at 844-757-9355. Our highly trained staff will be happy to assist you.

The Itamar WatchPAT ONE uses a finger sensor, pulse oximeter, movement detector, and a chest sensor to track data in 7 areas related to sleep wellness: abnormal respiratory events (central and obstructive), true sleep time, snoring and breathing patterns, oxygen saturation, heart rate, sleep stages, and body position.

The WatchPAT One Home Sleep Test is exclusively designed to test for obstructive and central sleep apnea. As a result, we only recommend the test for people with moderate to severe symptoms of these disorders. If you have a history of cardiorespiratory disease, stroke, insomnia, or hypoventilation should arrange for an overnight sleep study in a lab, rather than take the at-home test.

At-home sleep studies are an alternative to sleep studies conducted in a hospital or sleep laboratory. Your doctor may suggest an at-home sleep study if they think it is very likely that you have obstructive sleep apnea. 

Some common obstructive sleep apnea symptoms, signs, and risk factors include but are not limited to; snoring on the majority of nights of the week (loudness of snoring isn't as important as regularity of snoring), feeling unrefreshed after a full night's sleep, frequent awakenings during the night, and excessive daytime sleepiness or fatigue. 

Other, more subtle signs may indicate OSA, such as; extremely restless sleep, waking up in the morning with headaches, nighttime acid reflux, and feeling hot and sweaty during the night or needing the bedroom extremely cool.

Other factors that may also influence sleep apnea risk include but are not limited to: age, sex, race/ethnicity, family history, and lifestyle habits.

In 2007, the American Academy of Sleep Medicine issued a clinical guideline declaring that home sleep apnea tests were equivalent to in-lab sleep studies for the diagnosis of obstructive sleep apnea (OSA) in at-risk patients. You can read the guideline here. Diagnosing OSA is by far the most common reason to have a sleep study. In-home sleep studies cannot diagnose other sleep disorders besides sleep apnea. It is advisable that patients with certain medical problems such as advanced heart failure and lung disorders as well as people who are at risk for sleep disorders due to leg movements have an in-lab study. Consult your healthcare provider or a sleep specialist if you need advice on what type of sleep study may be best for your situation.

The WatchPAT ONE device is created for one night of use only, by one individual, and the data is sent electronically to the physician at the end of the sleep session. 

There is minimal night-to-night variability in sleep apnea so, for the purposes of diagnosing you with sleep apnea, only one night is needed. Experts recommend that home sleep apnea tests be taken only once. If the results are inconclusive or negative, you may be instructed to either repeat the test or do a polysomnography in a sleep lab to ensure accurate results.

The accuracy of home sleep apnea tests ranges widely, between 68% and 91%. The accuracy depends on the type of device used and whether you are at a high or low risk for having sleep apnea. The tests are significantly more accurate for people at a higher risk.

No, Singular Sleep does not require you to already have a prescription for a home sleep test. This will be included in your WatchPAT ONE home sleep test purchase.

Note: it is recommended that people with advanced lung disease, heart failure, or neuromuscular disorders like ALS have an in-lab sleep study. It is up to the discretion of the board-certified sleep provider to determine if an individual is eligible for an at home sleep study.

If you are having difficulty setting up the testing unit, please reference the easy to follow instructions that we included in the kit.

Should you need more information, this helpful video is available for you to watch.

If you are still unable to solve the problem, please call us during our normal business hours of Monday-Friday, 8 a.m. to 6 p.m. Eastern Time.

The type of mask that is best suited for you will vary from person to person.  Selecting the appropriate mask may take time as well as potential trial and error. Full face masks may be best suited for individuals who predominantly breathe through their mouth or have severe sinus issues. Nasal pillow masks may be best suited for individuals that are claustrophobic. Unfortunately, PAP masks are not a one size fits all product but we are here to help answer any questions you may have. Please contact us at 844-757-9355 to speak with one of our Clinical Sleep Therapy Specialists.

Full Face — Mask users with forehead pads/brace: tighten upper strap first, then follow with lower strap positioning and fit.

Mask Headgear — Masks come with a “one size fits most” headgear. Larger and smaller headgear may be available by special order.

Nasal Pillow Mask — Place the mask on your face and position the headgear; place side straps above the ears. Gently slip the nasal pillows into your nostrils, rotating the angle of the pillow barrel for a comfortable fit. The pillows lay just inside the nostril opening, not to be aggressively inserted. Proper placement should not cause the tip of the nose to be raised.

No mask should cause pain or discomfort if sized correctly and fitted properly. If irritation or sores develop, chances are that you are over-tightening your mask. Your mask cushion may be worn out and need replacement; over time, mask cushions deteriorate and can cause air leakage. If you are having problems with pressure on the bridge of your nose, Boomerang Gel Pads may solve the problem.

• Mask frame systems- replace every 6 months

• Cushions/pillows- replace every 3 months ( these may need to be replaced sooner depending on wear and tear)

• Headgear/chinstrap- replace every 6 months

• Filters- replace every 4 weeks

• Tubing- replace every 6 months

• Water chamber- replace every 6 months

• CPAP device- replace every 5 years

Your machine will be set up for you to begin using immediately. All devices will include user manuals that you may refer to. If you have any questions once you receive your device, please contact us at 844-757-9355 and one of our Clinical Sleep Therapy Specialists will be happy to assist you.

Practice makes perfect. To help get used to wearing the mask during sleep, practice by wearing it during the day while sitting in a chair watching television or reading. This will distract your focus from the mask to a positive, familiar activity. PAP use will become a habit and part of your routine.

There is an adjustment period, usually lasting about a week to ten days, for most patients as they get used to sleeping with the equipment. While your goal is to sleep all night with PAP, using it as long as you can tolerate it each night is better than no PAP therapy at all. Try to increase usage over time until you reach your goal. To help get used to wearing the mask during sleep, practice by wearing it during the day with the machine turned on and while sitting in a chair watching television or reading. This will distract your focus from the mask to a positive, familiar activity. If you think that you might struggle with claustrophobia, consider trying a nasal pillow masks as the relatively small size may be more tolerable for you.

All masks have exhalation ports to allow the escape of CO2 (carbon dioxide). The higher the machine pressure setting, the harsher this escape flow will be. Some masks have better air diffusion features than others. Some patients resolve this by side sleeping with their backs turned to their bed partner to avoid a distracting air flow.

All masks have exhalation ports (look for a tiny cluster of holes) that allow the escape of CO2 (carbon dioxide). When routinely cleaning your mask parts, these tiny holes must be checked to make sure they are not soiled and clogged by body oil or bedding lint. When clogged, they can cause the mask to make a whistling noise. Use a sewing needle or toothpick to keep the holes free flowing.

Mask leak is one of the most common challenges for patients. To assure the best fit and adjustment, when retiring to sleep, sit on your bed and place the mask on the head/face with straps loose. With the machine turned on and air blowing lay down with your head on the pillow in your normal sleeping position. Slowly tighten your mask straps just until you get a good seal, being careful not to needlessly over tighten. The final step is to “seat” your mask. After the straps are adjusted, pull the mask out and away from your face (about 2 inches) and gently lay back on your face. Mask fit varies with sleeping positions, so if you fit for side or stomach sleeping, you will need to readjust if you roll to your back. This is why many patients train themselves to sleep solely on their side or stomach (same mask fit) versus back sleeping, which has a different mask fit.

Often, side or stomach sleepers find their pillow causes unwanted mask frame movement (pushed off center) causing mask leak, pressure point soreness, or bruised cheekbones. You may consider trying a "CPAP Pillow" which is a specially made bed pillow designed for side- or belly-sleeping PAP users.

This commonly occurs while patients are getting used to therapy shortly after starting it but if this problem persists it may indicate one of the following issues:

• Your pressure may need to be adjusted. Not getting enough pressure at times during the night can cause patients to take the mask off due to a sense of claustrophobia. Most of the time, people don't remember this in the morning.
• You may be having periodic leak that is waking you up due to a REM sleep related phenomenon. The annoyance of the leak can cause a reflexive response of removing the mask. When your body enters REM sleep, all the muscles in your body relax and your lower jaw can drop down causing air to rush out of your mouth or break the seal if you're wearing a full face mask. We tend to have REM sleep periods at the same time every night so patients suffering with these issues will often report waking up at the same times, e.g. 3-3:30 a.m. and/or 5-6 a.m. every night. Using a chin strap is the best solution. If you're using a full face mask, you only have to apply the chin strap with modest tension; our goal is not to rigidly keep your mouth shut but to merely provide some gentle support for your jaw to prevent it from dropping way down during the night.
• Rolling to a side sleeping position may also break your mask seal and cause a similar response as described above. If you think this might be happening, try a CPAP pillow that allows the mask to nest into a cutout on the side of the pillow and decrease the chances of disrupting your mask seal.

Snoring, choking, and gasping noises should be eliminated during PAP use. If not, it could mean that your machine pressure is not adequate or your "leak" is high. Please contact a member of our Singular Sleep staff to discuss further.

The medical term for this common PAP issue is aerophagia. Aerophagia occurs when the air delivered by your machine enters the esophagus and stomach and not the airway. It can occur when your machine pressure is set too high or if you are a mouth breather and prone to swallowing air - this happens more often with full face masks.  Possible solutions include using a chin strap, turning down the pressure, and increasing the humidification setting. 

This is a typical complaint from BiPAP users at first. It mainly occurs because your wakeful breathing differs from your sleep breathing. It is more irregular, especially because you may anticipate what the machine will do and try to match that. The machine was designed for sleep breathing which is very regular. Once you get to sleep, the machine should synchronize with your breathing. We recommend trying to do relaxation breathing exercises to regulate your breathing and just be persistent with it. More than likely you'll get used to it over the course of the next few nights.  Most patients report that within two weeks, they find they have grown accustomed to using the machine. If you’re really struggling with this, please let us know and we may be able to adjust a setting on your machine that might help.

Try using the “Ramp” option on your therapy device. Designed to make therapy more comfortable, the Ramp feature helps you ease into therapy each night by setting your device at a lower pressure than prescribed and slowly ramping up to your full therapy pressure over a maximum of forty-five minutes. Using Ramp gives your machine more time to gradually reach your prescribed therapy pressure — and gives you more time to comfortably fall asleep. We recommend setting the Ramp to the typical time that it takes you to fall asleep. So if it takes you, on average fifteen minutes to fall asleep, set the Ramp to fifteen minutes. 

Make sure the electric plugs to the wall and to the machine are firmly in place. Check your electric outlet to make sure it is working. Make sure the humidifier is closed and your tubing is connected properly to the machine. If this does not fix the problem, please contact us at 844-757-9355 to speak with one of our Clinical Sleep Therapy Specialists so we can better assist you.

Try running the tubing behind your head and over the headboard and then looping it around to your PAP machine. If that doesn't work, consider purchasing a hose management system which can help keep your tubing neat and tangle-free while you sleep. 

Standard CPAP tubing is six feet in length. Active sleepers who toss and turn are more apt to tug on the tubing and pull their machine off the bedside table. Extra-long tubing may help with this problem.

Excess condensation can form in the CPAP tubing when the temperature of your bedroom is colder than the air coming from your machine. This is called "rain out" and can be resolved by using an insulated sleeve over your tubing or changing to heated tubing.

Germs and minerals can accumulate in the water chamber. All manufacturers recommend the use of distilled water.  Each morning, empty any leftover water, rinse chamber, and let air dry. To remove the film, fill the chamber with 1/3 white distilled vinegar to 2/3 tap water solution. Let soak for one hour. Rinse with clear tap water; air dry. 

Always remove the water chamber unit from the machine before filling with distilled water. Also, make sure your PAP machine is always placed on a level surface. Spilling water into the machine may compromise the interior circuits, damage the machine, and void the warranty so dry the machine carefully if you have an accident.

Today’s machines are nearly silent, so unless you are hypersensitive to noise (try earplugs), this would indicate a problem. Check the machine filters. They should be changed monthly or when visibly discolored to help keep the machine running smoothly. There will be a slight audible noise if you are using a Bi-Level machine as the pressure transitions between inhalation and exhalation settings. There will be a slight audible noise if you use an APAP as the machine changes inhalation pressure. If your machine is otherwise excessively noisy, there may be a machine defect.
