Re: question about PR System One REMstar BiPAP Auto with Bi-Flex
How can I tell if I got the NEWER version or older version. I am newbie that just got this machine 5 days ago and I can't tell which one it is. I know that the hose looks like the 22mm but what else should I be able to see to clue me into which one I have?
