Two Different Approaches
CPAP and Inspire both treat obstructive sleep apnea effectively, but they work in fundamentally different ways. CPAP uses external air pressure to splint the airway open; Inspire uses internal nerve stimulation to keep the airway muscles active during sleep.
CPAP: Pros and Cons
Pros:
- Most studied and proven sleep apnea treatment
- Non-invasive — no surgery required
- Effective for all severities of OSA
- Immediate results when used properly
- Lower upfront cost
Cons:
- Requires wearing a mask every night
- Can be uncomfortable for some patients
- Adherence is a common challenge
- Noise, dry mouth, and claustrophobia issues
Inspire: Pros and Cons
Pros:
- No mask, hose, or machine
- Works with your body's natural breathing
- High patient satisfaction and adherence rates
- Simple to use — click a remote before bed
Cons:
- Requires a surgical procedure
- Strict candidacy criteria (AHI 15–100 and BMI up to 40 under the FDA label; many insurers require less)
- Not suitable for all types of airway collapse
- Battery replacement needed after ~11 years
- Higher initial cost (usually covered by insurance)
Which Is Right for You?
The decision between CPAP and Inspire should be made with your sleep specialist based on your diagnosis, CPAP experience, anatomy, and personal preferences. Most patients start with CPAP, and Inspire is considered when CPAP is not tolerable.
Key Takeaways
- CPAP is the first-line treatment; Inspire is for CPAP-intolerant patients
- Both are clinically proven to reduce AHI and improve symptoms
- Inspire offers a mask-free option but requires surgery and specific criteria
- Work with your sleep doctor to determine the best option for you
