Getting a sleep apnea diagnosis is one thing. Figuring out what to do next is another. There’s a lot of information out there, some of it helpful, a lot of it confusing, and the treatment landscape has expanded considerably over the past decade. CPAP is still the most effective first-line treatment for most people, but it’s far from the only option.
This guide walks through the main treatment pathways for obstructive sleep apnea, who each one suits, and how to think about your choices. The goal isn’t to steer you toward any particular option. It’s to give you enough context to have a useful conversation with your respiratory therapist or physician.
Why Treatment Actually Matters
Sleep apnea isn’t just a snoring problem. Left untreated, it puts real strain on your cardiovascular system. Your airway partially or completely closes dozens of times per hour, each time dropping your blood oxygen and jolting your nervous system back to a lighter sleep stage. Over time, that repeated stress raises your risk of hypertension, heart disease, type 2 diabetes, and stroke.
The other side of it is quality of life. Chronic fatigue, difficulty concentrating, mood changes, and memory problems are all common in untreated sleep apnea. Most patients who follow through on treatment report meaningful improvements in energy and mental clarity fairly quickly.
If you’re still in the diagnostic stage, Northern Respiratory’s sleep studies and funding page has information on testing options in Ontario, including what provincial programs cover.
CPAP Therapy: The Gold Standard
CPAP (Continuous Positive Airway Pressure) remains the most widely prescribed and most thoroughly studied treatment for obstructive sleep apnea. It works by delivering a continuous stream of pressurized air through a mask, keeping your airway open throughout the night so the obstructions don’t occur.
The word “continuous” is key. Your prescribed pressure stays constant across the night, at a level set by your physician based on your sleep study results. This is different from BiPAP, which adjusts pressure between inhalation and exhalation.
Most patients who stick with CPAP therapy see significant improvement. The most common reason it doesn’t work isn’t the therapy itself. It’s mask fit, pressure discomfort, or not having proper setup support from a respiratory therapist.
What a Good CPAP Setup Looks Like
A well-fitting mask is the foundation. Nasal masks, nasal pillow masks, and full face masks each suit different sleeping styles and breathing patterns. Northern Respiratory’s clinicians do in-person fittings using dedicated fitting rooms with reclining chairs, so you can test a mask at your actual prescribed pressure before committing.
From there, ongoing follow-up matters. You can read more about the full CPAP and BiPAP therapy process at Northern Respiratory, including what the first few weeks typically look like.
Auto CPAP (APAP): A Flexible Alternative
Auto-adjusting CPAP, often called APAP, uses an algorithm to adjust pressure in real time based on what your airway needs at any given moment. Instead of a fixed pressure all night, the machine delivers only as much as required.
For many patients, this is more comfortable. On nights when your sleep position, congestion, or alcohol intake means you need less pressure, the machine backs off. On nights when your airway is more prone to obstruction, it responds accordingly.
Devices like the ResMed AirSense 11 operate as auto-adjusting CPAP machines with a built-in humidifier and remote monitoring capabilities. Your clinician can review your therapy data and make adjustments remotely without you needing to come in for every follow-up.
You can explore available CPAP machines at Northern Respiratory to get familiar with current options before your appointment.
BiPAP Therapy: When CPAP Isn’t Enough
BiPAP (Bi-Level Positive Airway Pressure) delivers two distinct pressure levels: a higher pressure when you inhale and a lower pressure when you exhale. This makes breathing feel more natural, particularly for patients who find it hard to exhale against continuous pressure.
BiPAP is typically recommended when CPAP therapy hasn’t been effective, when a patient requires higher pressure settings that are uncomfortable on a standard machine, or when the diagnosis involves a more complex condition beyond straightforward obstructive sleep apnea, such as central sleep apnea or certain neuromuscular conditions.
It requires a physician’s prescription and a clinical assessment. It’s not a first-line treatment for most patients, but for those who need it, the difference is meaningful.
Oral Appliance Therapy
For patients with mild to moderate obstructive sleep apnea, a custom-fitted oral appliance is sometimes an option. These devices, often called mandibular advancement devices, reposition the lower jaw slightly forward during sleep, which helps keep the airway open.
They’re most useful for people who can’t tolerate CPAP for any reason, or for occasional use when travel makes CPAP impractical. However, they’re generally less effective than CPAP for moderate to severe sleep apnea, and they require fitting by a dentist with experience in sleep medicine.
Positional Therapy
Some patients have positional sleep apnea: their obstruction happens almost entirely when sleeping on their back. In these cases, positional therapy (using devices or techniques that encourage side sleeping) can reduce the frequency of apnea events.
It’s rarely a complete solution on its own, but for the right patient profile, it can meaningfully reduce severity and sometimes reduce the pressure settings needed for CPAP therapy.
Lifestyle Changes That Support Treatment
Lifestyle factors don’t replace clinical treatment, but they can affect severity and how well therapy works. Weight loss reduces the tissue pressure on the airway and can lower the AHI (apnea-hypopnea index) in some patients. Reducing alcohol intake, particularly in the hours before sleep, relaxes throat muscles less and can reduce obstruction frequency. Avoiding sleeping on your back also helps many people.
None of these replace a prescribed therapy, but your clinician may factor them into your overall treatment plan.
How to Choose: A Comparison
| Treatment | Best For | Key Consideration |
|---|---|---|
| CPAP | Most patients with OSA | Mask fit is critical to success |
| APAP | Variable pressure needs, comfort | More flexible; still requires fitting |
| BiPAP | High pressure needs, complex cases | Requires specific clinical indication |
| Oral Appliance | Mild to moderate OSA, CPAP intolerance | Less effective for severe cases |
| Positional Therapy | Positional OSA only | Usually a complement, not standalone |

Frequently Asked Questions
Is CPAP the only treatment for sleep apnea?
No, it’s the most effective first-line treatment for most patients, but not the only one. BiPAP, APAP, oral appliances, and positional therapy are all viable depending on the severity and type of your sleep apnea. Your physician and clinician will guide you toward what fits your situation.
What if I can’t tolerate CPAP?
Intolerance is often a fit or setup problem rather than an inherent incompatibility. The most common issues (mask leaks, claustrophobia, pressure discomfort) can usually be addressed with a different mask style, a humidifier, or a pressure ramp setting. If none of those work, other options like BiPAP or an oral appliance may be appropriate.
Does sleep apnea go away on its own?
In most cases, no. Structural factors and airway anatomy don’t resolve without intervention. Significant weight loss can reduce severity in some patients, but clinical treatment remains necessary for the large majority of people with obstructive sleep apnea.
What is a sleep therapy clinic?
A sleep therapy clinic provides assessment, equipment fitting, follow-up care, and ongoing support for people with sleep disorders. Northern Respiratory functions as a full-service respiratory home care provider. You can learn more at Northern Respiratory’s sleep apnea therapy page.
