Probably like most CPAP therapy patients I tend to forget to maintain my gear on a regular basis. The CPAP itself doesn’t require much – just occasional cleaning of the water reservoir. However, the mask and associated parts wear out every now and then and need to be replaced.
I use a full-face mask, which is strapped to my face with elastic “headgear”. Over time it will slowly stretch and eventually it won’t fit as well as it used to. This isn’t the first time I’ve had this problem and it’s a gradual one so I tend to forget how much of a difference new headgear makes.
I finally ordered a new set of straps from CPAP.com and it has made a huge difference. The old strap had stretched so much that the Velcro had started scratching the back of my neck late at night and sometimes leaving a mark (and an itchy neck).
So, if you find your CPAP doesn’t seem to be working as well keep in mind that it might just be an issue with the headgear.
