Common CPAP Problems and How to Solve Them
Using a CPAP machine is one of the most effective ways to treat sleep apnea, but it can take time to adjust. Many users experience challenges—like air leaks, dry mouth, or discomfort—that can make therapy frustrating at first. The good news? Most of these issues have simple solutions.
In this guide, we’ll cover the most common CPAP problems and how to fix them so you can enjoy comfortable, consistent sleep therapy.
1. Air Leaks from the Mask
Air leaks can prevent your CPAP from delivering the correct pressure, causing dry eyes, noise, or restless sleep.
- Adjust the headgear straps so the mask sits snugly but not too tight.
- Check the mask cushion for wear or cracks and replace it every 1–3 months.
- Make sure the mask size and style match your face shape.
Tip: Clean your mask daily—oils from your skin can break the seal and cause leaks.
2. Dry Mouth or Throat
Waking up with a dry mouth or throat often means your air pressure or humidity levels are too low—or you’re breathing through your mouth.
- Use a heated humidifier or increase the humidity setting.
- Try a full-face mask if you’re a mouth breather.
- Use a chin strap to help keep your mouth closed during sleep.
- Stay hydrated throughout the day to reduce dryness.
Pro Tip: Adjust humidity gradually until you find your comfort zone.
3. Nasal Congestion or Dryness
Cool, dry air from your CPAP can irritate nasal passages, causing congestion or nosebleeds.
- Use a heated humidifier and heated tubing to add moisture and warmth to the airflow.
- Try a saline nasal spray before bed.
- Ensure your mask fits properly—air leaks near the nose can worsen irritation.
Bonus Tip: Keep your room at a comfortable humidity level (around 40–50%) to prevent dryness.
4. Difficulty Falling Asleep with CPAP
It’s common to feel uncomfortable or restless when first using your CPAP machine. The constant airflow or the sensation of pressure can make it hard to relax.
- Wear your mask for short periods while awake to get used to the feeling.
- Use the “ramp” feature, which starts at a lower pressure and gradually increases as you fall asleep.
- Create a relaxing bedtime routine—avoid screens and caffeine before bed.
Pro Tip: Consistency is key. The more often you use your CPAP, the faster your body adjusts.
5. Pressure Feels Too High or Too Low
If your air pressure feels uncomfortable, it may cause bloating, discomfort, or poor sleep quality.
- Use the ramp setting to start with lower pressure.
- Check your mask for leaks—this can make pressure feel inconsistent.
- Consult your sleep specialist if pressure feels wrong or causes discomfort.
Note: Never adjust pressure settings yourself unless advised by a healthcare provider.
6. CPAP Noise Disturbing Sleep
Some CPAP machines or masks can produce a low humming or whistling noise that disturbs sleep.
- Place the machine on a flat, stable surface.
- Clean air filters and tubing regularly to avoid dust buildup.
- Inspect mask connections for leaks that can cause whistling sounds.
Pro Tip: Modern CPAP models like the ResMed AirSense 11 are ultra-quiet and user-friendly.
7. Skin Irritation or Red Marks
Tight straps or friction from the mask can leave red marks or irritate your skin.
- Loosen the headgear slightly—your mask should be snug but comfortable.
- Use mask liners or silicone pads for added comfort.
- Wash your face before bed to remove oils that can cause irritation.
Bonus Tip: Rotate between two masks to reduce skin pressure and irritation.
Final Thoughts
Most CPAP problems are easy to fix with simple adjustments. Whether it’s fine-tuning your mask fit, adding humidity, or replacing worn parts, small changes can greatly improve your comfort and sleep quality.
Remember, successful CPAP therapy is about consistency and comfort. If issues persist, consult your sleep specialist or equipment provider for professional advice. With the right setup and care, you can breathe easier, sleep deeper, and wake up feeling refreshed.
