ResMed Chin Strap

Sobre ResMed Chin Strap

ResMed chin strap — a neoprene strap that holds the jaw closed during nasal CPAP therapy, so the pressure stays where it should instead of escaping through the mouth. It is 157 cm long and washable.

Why a chin strap matters with a nasal mask

If your mouth falls open during the night on a nasal or pillow mask, the air the machine delivers goes straight out again. The pressure at the airway drops, the therapy does less, and the airflow across the mouth dries out the mouth and throat — which is why people wake up parched and assume the humidifier is at fault.

The strap cups the chin and fastens over the top of the head with hook-and-loop, holding the jaw in position without clamping it. It goes over or under the mask headgear on most masks, and the neoprene washes in warm water with a mild detergent.

Benefits of the chin strap

Who is it for?

The strap is for you if you use a nasal mask or a pillow mask and suspect your mouth opens at night. The usual signs are a dry mouth on waking and therapy that feels less effective than it should. If mouth breathing continues, a full face mask may be the better answer — talk to your clinic.
