CPAP and Alternatives

CPAP — continuous positive airway pressure — is the most evidence-backed treatment for moderate-to-severe obstructive sleep apnea. It's also the most commonly abandoned. Both things are true.

How CPAP actually works

A CPAP machine pushes a steady stream of pressurized air through a mask, gently splinting your airway open. Without the obstruction, your breathing stays steady, sleep stages cycle normally, and your body finally gets to do its repair work overnight.

When it works, the change is dramatic. People often describe waking up feeling rested for the first time in years. Long-term, CPAP improves blood pressure, daytime alertness, and cardiovascular risk for people with significant sleep apnea.

Why people stop using it

Adherence is the open secret of CPAP. Studies suggest only about half of users are consistent at 6 months. The reasons are practical:

• Mask fit — leaks, pressure marks, claustrophobia
• Dryness or congestion (often fixable with a heated humidifier)
• Noise (modern machines are very quiet, but partners' perceptions vary)
• The hassle of cleaning and traveling with it

Most CPAP failures aren't because CPAP doesn't work — they're because the mask, pressure, or setup wasn't optimized. Working with a sleep clinic to fine-tune is often the difference.

Modern alternatives

1. Oral appliance therapy (mandibular advancement devices)

A custom-fitted device worn like a retainer that gently advances your lower jaw, opening the airway. Evidence supports it as a strong first-line option for mild-to-moderate OSA and snoring. Works best when fitted by a dentist trained in dental sleep medicine — over-the-counter "boil and bite" versions are far less effective and can cause jaw issues.

2. Positional therapy

Some people only have apnea when sleeping on their back. For positional sleep apnea, dedicated devices (vibrating belts or sensors) train you to side-sleep and can dramatically reduce events.

3. Hypoglossal nerve stimulation

An implanted device that stimulates the nerve controlling tongue movement, keeping the airway open during sleep. FDA-approved for select people with moderate-to-severe OSA who can't tolerate CPAP.

4. Surgery

Procedures that address specific anatomy — enlarged tonsils, a deviated septum, or excess soft palate tissue — can be appropriate for the right candidate. Outcomes vary widely; consultation with an ENT specializing in sleep is essential.

5. Weight management

For OSA driven by excess weight, even modest reduction (10% of body weight) can substantially lower apnea severity — sometimes enough to reduce or eliminate CPAP pressure needs.

What to do if you're considering treatment

1. Confirm the diagnosis with a sleep study if you haven't.
2. If you have moderate-to-severe OSA, give CPAP a real, supported try with an experienced sleep clinic.
3. If CPAP isn't a fit after honest effort, discuss alternatives with a sleep specialist — there are more options today than ever.

The bottom line

CPAP is the most effective treatment we have, but it's not the only one. The right approach depends on the severity of your apnea, your anatomy, and your lifestyle. Our assessment can help you understand where you fall on the spectrum so you can have a more focused conversation with your care team.
