The adjustable Puresom Ruby chin strap manufactured by CareFusion is upgraded with Breath-o-Prene material and improved Velcro attachments. It helps to hold the patients’ mouth closed during their CPAP or BiPAP. Every person’s requirements are different. So, before purchasing a chin strap we recommend purchasing return protection policy with the chinstrap.
Sitting in a comfortable chair, measure the chin circumference below the ears to the back of the neck. Hold the tape horizontal to the floor. Select Small if the circumference is less than 21 inches. If the circumference measures between 21 and 23 inches, choose Medium. Large straps are mostly used by people whose chin circumference is greater than 23 inches.
