Encircles the head and attaches to itself on the top of the head. Can be used with any mask, nasal pillow or nasal prong system. Use a chinstrap if your mouth is drying out.
Chin straps are often used for those patients who experience problems associated with mouth-breathing during their PAP therapy.
A chin strap can solve these problems by holding the mouth closed during sleep, and may prevent the patient from having to wear a full face CPAP mask.
