CPAP Basics
How CPAP Therapy Works
CPAP (Continuous Positive Airway Pressure) delivers a steady stream of pressurized air through a mask to keep the upper airway open during sleep. The pressure acts as a pneumatic splint, preventing the throat tissues from collapsing and blocking airflow.
Pressure
Prescribed pressure ranges from 4–20 cmH₂O. APAP (auto-adjusting) devices adapt each night to deliver the minimum effective pressure automatically.
Effectiveness
When used consistently, CPAP reduces AHI by 80–90%, eliminates or reduces snoring, and restores normal blood oxygen saturation throughout the night.
Compliance
The average CPAP user wears it 5.5 hours per night. Research consistently shows 6+ hours per night is associated with the greatest reduction in daytime sleepiness and cardiovascular risk.
Key Fact
CPAP is effective only when worn. The average CPAP user wears it 5.5 hours per night, and 6 or more hours per night is associated with the greatest symptom relief and health benefit.
Mask Guide
The 4 CPAP Mask Types: A Complete Guide
Mask type is the most common reason people discontinue CPAP therapy. Understanding your options makes it easier to find a fit that works for how you actually sleep.
Most Minimal
Nasal Pillow Mask
The smallest and lightest mask design. Two soft silicone cushions insert just at the nostrils, with no frame covering the nose or face. Ideal for nose breathers, side sleepers, people with facial hair, and those who feel claustrophobic with larger masks.
Limitation
Not suitable for mouth breathers. May become ineffective above approximately 15 cmH₂O pressure due to air leaking around the nostrils.
Most Common
Nasal Mask
Covers the nose from bridge to upper lip. The most commonly prescribed starter mask, offering a balance of stability and comfort. Well-suited for active sleepers, moderate-to-high pressure needs, and nose breathers who want more stability than nasal pillows provide.
Limitation
Requires nasal patency. Opening the mouth during sleep causes air to escape, reducing therapy pressure. A chin strap can help.
Mouth Breathers
Full-Face Mask
Covers both nose and mouth with a single sealed cushion. The right choice for mouth breathers, people with frequent nasal congestion or allergies, high CPAP pressure needs (above 15 cmH₂O), and back sleepers who tend to breathe through the mouth.
Limitation
More bulk and surface area can feel claustrophobic. Harder to achieve a consistent seal, especially for side sleepers. More components to clean and replace.
Mixed Breathers
Hybrid Mask
Combines nasal pillow inserts with an oral cushion to cover the mouth, without the full face seal of a traditional full-face mask. Designed for people who switch between nose and mouth breathing, or who want less facial bulk than a full-face mask.
Limitation
More complex to fit correctly. Less widely available than other types. May require more trial and adjustment to find a comfortable, leak-free position.
Side-by-Side
CPAP Mask Comparison Table
A quick reference to compare the four mask types across the factors that matter most for comfort and effectiveness.
| Type | Coverage | Mouth Breathing OK | Pressure Range | Claustrophobia Risk |
|---|---|---|---|---|
| Nasal Pillows | Nostrils only | No | 4–15 cmH₂O | Very Low |
| Nasal Mask | Nose | No | 4–20 cmH₂O | Low |
| Full-Face | Nose + Mouth | Yes | 4–20+ cmH₂O | Moderate–High |
| Hybrid | Nostrils + Mouth | Yes | 4–20 cmH₂O | Low |
Adherence Tips
Tips for CPAP Compliance and Comfort
The first few weeks are the hardest. These evidence-backed strategies make the adjustment period shorter and improve long-term use.
- 1
Acclimatize before bed
Wear the mask for short periods during the day while awake, watching TV or reading. This helps your brain stop treating the mask as a foreign sensation before you need to fall asleep in it.
- 2
Ensure a proper fit first
Even a small leak causes pressure to drop, reducing therapy effectiveness. Adjust the headgear while lying in your normal sleep position, not while standing in front of a mirror.
- 3
Use the heated humidifier
Pressurized air is dry. Heated humidification reduces nasal dryness, congestion, and mask leaks caused by instinctively mouth breathing due to discomfort. Most modern CPAP machines include one.
- 4
Follow the replacement schedule
Replace cushions or pillow inserts monthly, headgear every 6 months, and the mask frame every 6–12 months. Worn components cause leaks and reduce seal quality, and most insurance covers replacements.
- 5
Track how you feel
Keep a brief daily log of alertness, energy, and sleep quality. Improvement in daytime functioning, even subtle at first, is the most powerful motivator for continued CPAP use.
- 6
Ask about APAP if pressure is uncomfortable
Auto-adjusting PAP (APAP) delivers only the pressure you need at each moment rather than a fixed setting. Many people find APAP more comfortable, especially during lighter sleep stages. Ask your sleep physician if it is appropriate for you.
Summary
Key Takeaways
- CPAP therapy reduces AHI by 80–90% when worn correctly and consistently, making it the most effective treatment for moderate-to-severe OSA.
- Mask type is the most common reason people discontinue CPAP. Getting the right fit for your breathing pattern matters as much as the machine itself.
- Nasal pillow masks are the most comfortable option for most people, but they require nose breathing and are not suitable above about 15 cmH₂O.
- Full-face masks are the right choice for mouth breathers or people with frequent nasal congestion, despite their added bulk.
- Heated humidification significantly improves comfort and compliance rates. Use it from night one if your machine includes it.
