CPAP Not Working? Here's What to Check First

If your CPAP machine isn’t working the way it used to, don’t worry many issues have simple fixes you can do at home. In this guide, we’ll cover the most common problems and how to troubleshoot them before calling for support.

1. Check the Mask Fit

A mask that’s too loose or the wrong style can cause air leaks. Adjust the straps so the mask is snug but comfortable. If leaks persist, you may need a different mask type, like nasal pillows, a nasal mask, or a full-face mask.

2. Make It Part of Your Routine

If you’re new to CPAP, it can take time to get used to it. Try wearing your mask for short periods during the day while reading or watching TV. This helps you adapt before using it all night.

3. Adjust the Pressure Settings

If you feel discomfort from the air pressure, look for a “ramp” feature on your machine. This starts at a lower pressure and gradually increases as you fall asleep.

4. Manage Dryness or Stuffy Nose

Dry or congested airways are common. Using a heated humidifier or saline nasal spray can make breathing more comfortable.

5. Reduce Noise and Leaks

If your CPAP is noisy or leaking, check the tubing, seals, and filters. Make sure everything is clean, dry, and connected properly.

When You May Need Extra Help

• Your symptoms (snoring, daytime fatigue) haven’t improved.

• The machine is more than 5 years old and performance is declining.

• You notice water in the tubing (“rainout”) or frequent air swallowing (aerophagia).

These are signs to check your settings with a healthcare provider or consider a replacement.

Common Questions

Why is my CPAP blowing cold air?
This may be condensation in the tubing. Try heated tubing or lower the humidifier temperature.

Why am I still tired with CPAP?
It could be leaks, incorrect pressure, or another sleep issue. Have your settings reviewed.

What if my mask still feels uncomfortable?
Consider a different style or size. A small adjustment can make a big difference.

Time for an Upgrade?

Technology improves quickly, modern CPAP machines are smaller, quieter, and offer smarter comfort settings. If your current device is aging or no longer meeting your needs, it might be time to explore new options.
