ResMed Chin Restraint

The ResMed Chin Restraint is an essential PAP mask accessory designed to restrict mouth opening during Positive Airway Pressure (PAP) therapy . By keeping your mouth gently closed during sleep, it prevents air loss through the mouth—ensuring your sleep apnea therapy remains effective, comfortable, and uninterrupted .

Who Is This Product For?

This accessory is ideal for CPAP, APAP, or Bilevel patients using nasal masks, nasal pillows masks, or nasal cradle mask systems who suffer from mouth leaks or mouth breathing during sleep . It is especially helpful for individuals who wake up with a dry mouth, sore throat, or nasal congestion while receiving PAP therapy .

What Problem Does It Solve?

When sleeping with a nasal mask or pillow system, involuntary mouth opening causes therapy pressure to escape through the mouth . This "mouth leak" reduces the efficacy of your PAP therapy, leads to air dryness, and disrupts sleep quality . The ResMed Chin Restraint maintains gentle upward pressure to keep the lower jaw stable and lips closed, maximizing air delivery directly to your airway .

Application Guide & Fitting Instructions

Note: The ResMed Chin Restraint must be fitted on your head BEFORE you put on your CPAP mask .

1. Position the Restraint: Place the strap over your chin so that the edge with the stitched "V" mark is positioned closest to your bottom lip .
2. Fasten Straps: Bring the side straps up past your cheeks and fasten the Velcro® closure securely at the top (crown) of your head .
3. Adjust Support: If necessary, adjust the strap tension to provide sufficient upward support for your chin without overtightening . Ensure it feels secure before placing your CPAP mask over it .
