pressure check

Does anybody check cpap machine pressure and if so what gauge do you use and where can i get one? my machine is a little over eight months old now and it seems like it doesn't blow as strong as when it was new.

Dale,

Here's some from our host. I would probably select the second one if it were me. It's cheaper and you can also use it as a pass-over humidifier.
I've never checked mine. If you got your machine from a local DME, they should be able to check it for free.

Checking it is a good idea, but the problem you see is probably you are getting used to the pressure. The more you use the pressure the more the body makes it the norm. Jim

the LCD display and the actual delivery pressure can be off, think they list a +/- 1cm tolerance.

a water-based simple U-tube manometer will be the most accurate, you can make one from a yard stick and some 1/8" ID clear hose and some water if you have a ruler with "cm" increments. You can connect it to the oxygen port on the mask, without a mask you need to make sure there is an intentional leak using a 4mm exhaust hole.

The 2nd link Wulfman posted has the Fisher and Paykel manometer, it works very well and is accurate, you don't need to use a mask with it, it has a 4mm exhaust hole on the gray plug.

You don't use them very often, so I wouldn't spend a lot of money on one, the $90 gage style is convenient but it won't be any more accurate.

My first reaction is what Jim said. It may simply be that it doesn't feel like as much pressure because you're getting used to it. If that's what it is, take it as a good sign.
