Why am I breathing through my mouth with CPAP therapy?

Mouth breathing can happen for various reasons.  It’s often due to nasal congestion, habits formed over time, or simply, comfort.  Your CPAP machine is designed to deliver air through your nose, while mouth breathing the air pressure escapes, reducing the effectiveness of your therapy.

What issues can mouth breathing cause?

  • Dry mouth and throat
  • Reduced effectiveness
  • Increase air leaks

How do I prevent mouth breathing while using my CPAP machine?

  • Use a chin strap
  • Switch to a full-face mask
  • Try nasal strips or sprays to help clear congestion
  • Practice breathing exercises to strengthen nasal breathing

Can changing my CPAP pressure help reduce mouth breathing?

In some cases, adjusting your pressure settings can help.  If the pressure feels too high, it may make nasal breathing uncomfortable, causing you to try to breathe through your mouth.  Consult your Sleep Therapeutics clinician to assist you.

If you have tried these tips but continue to breathe through your mouth with your CPAP machine, consider speaking with your clinician.  Persistent mouth breathing can reduce the effectiveness of your therapy, so it is important to address it as soon as possible.  Your clinician will work with you to find a solution that is tailored to your needs.
