Thank you for reading this post, don't forget to subscribe!Feeling like you’re not getting enough air when using CPAP is one of the most common beginner frustrations. It can feel like you’re “air hungry,” suffocating, or struggling to exhale. The good news? This sensation is almost always caused by settings or mask fit — and it’s very fixable.
This guide explains why CPAP can feel like not enough air and how to fix it quickly.
Why CPAP Can Feel Like You’re Not Getting Enough Air
The “air starvation” sensation usually comes from:
- Pressure starting too low
- Ramp mode set too long
- Mask too tight or restrictive
- Mouth breathing with nasal pillows
- Claustrophobia or anxiety
- Wrong mask style for your breathing pattern
Let’s walk through the most effective fixes.
1. Reduce or Shorten Ramp Time
Ramp mode starts your pressure low and slowly raises it. Many beginners confuse low pressure with “not getting enough air.”
Fix:
- Shorten the ramp time
- Or turn ramp mode off entirely
Most users feel instant relief once pressure starts at a comfortable level.

2. Increase Minimum Pressure (With Guidance)
If your starting pressure is too low (for example, 4 cmH₂O), breathing may feel suffocating.
Fix: Talk to your provider about raising your minimum pressure slightly — many users breathe more comfortably starting at 6–7 cmH₂O.
3. Use EPR (Expiratory Pressure Relief)
If exhaling feels difficult, EPR reduces pressure during exhalation.
Fix: Set EPR to 1–3 to make breathing feel more natural.
4. Switch to a Less Restrictive Mask
Some mask styles can feel too “closed-in,” especially full-face masks.
If you feel suffocated, try:
- Nasal pillow masks — very open, least restrictive
- Nasal masks — good balance of airflow and comfort
5. Avoid Over-Tightening the Mask
When the mask is too tight, airflow can feel restricted and uncomfortable.
Fix: Loosen straps slightly and let the cushion inflate naturally.

6. Address Mouth Breathing
If you’re using a nasal mask but mouth breathing, you may feel like you’re not getting enough air.
Fix: Use a gentle chin strap to support the jaw.
If mouth breathing continues, a full-face mask may work better.
7. Check for Mask Leaks
Leaks reduce effective pressure, making it feel like you’re not getting enough air.
Fix: Adjust mask fit and replace worn cushions.

8. Manage Claustrophobia or Anxiety
Sometimes the sensation of “not enough air” is anxiety-driven, especially for beginners.
Fixes:
- Use the mask during the day for short sessions
- Practice slow 4–6 breathing
- Switch to a minimal-contact mask

9. Ensure the Hose Isn’t Kinked or Blocked
A bent hose or clogged filter can restrict airflow.
Fix:
- Check the hose for kinks
- Replace filters every 2–4 weeks
Quick Summary: How to Fix “Not Enough Air” Sensation
- Shorten or disable ramp mode
- Increase minimum pressure (with guidance)
- Turn on EPR
- Ensure mask is not too tight
- Try a less restrictive mask
- Fix leaks and replace cushions
- Use a chin strap if mouth breathing
- Check hose and filters
- Practice slow, calming breathing
Final Thoughts
Feeling like you’re not getting enough air is common — but almost always easy to fix. With better pressure settings, a comfortable mask style, and small adjustments to your routine, CPAP can feel effortless and natural.
