I am interested in trying the Fisher & Paykel new Oracle 452 system. I cannot breath through my nose when I sleep and am Rescue Diver so I am used to breathing off something in my mouth. Does it work well? The full face masks I have used are so obtrusive and they leak.

Are they hard to get used to? Any complaints about them? Are they easy to exhale in?

Hi tom,

I have the Oracle you're talking about. You can read my thoughts on it in a previous topic:

new Oracle 452

I don't use it much since the ResMed Ultra Mirage FF (full face) mask suits me well for congested nights. But I still do use the Oracle (and the nose plugs!) occasionally for naps when I have a cold. Doesn't happen all that often, thankfully.

If I had not been able to find a full face mask that worked for me, I'd be using the Oracle more.
