Which C-Flex level are you using?

Being new to C-Flex, I figured that if a setting of 1 is good, then 3 must be better Seems to work well for me.

Why would I want to think about using settings of 1 or 2?

derek

For higher pressures I like 2 or 3. (over 10) Under 10 anything over 1 seems uncomfortable (as you get a maskful of hot air (yours) til it flushes out. YMMV

(I am a mouth breather so I use a Ultra Mirage FF)

I find, as with many other things, it really depends a lot on masks.

With the Swift, I find CFLEX of 3 is great.

On the other hand, with the Activa and the Ultra Mirage, I found 3 felt too odd, I felt like I was breathing out in a rush (almost like a heavy-breathing exhale), because I started to exhale against the pressure, only to have it drop and the air WHOOOSH out of me like a punctured balloon. I didn't like it at all.

So with the Activa and the Ultra, I found 1 to be good, perhaps even off to be good. With the swift, I like 3.

Liam, his goes to 11.

I've tried all three and stayed with 3. I use the auto set at 6cm to 13cm with a titrated pressure of 7cm. I have no problems with a mask full of hot co2, but then again I use the Swift nasal pillows. The comfort of the Remstar auto with C-flex set a 3 is unsurpassed.

OK, this is trivial, even for me, but I read "co2" as "co squared", which then became "coco" or "cocoa", and before I figured out what Wader was saying, I wondered why he had a mask full of hot cocoa.

Am I weird, or what?

Liam, who is weird.

Tell me how to enter subscript in BBcode and I'll save you a trip into Alice's wonderland next time.

I'm amazed by how your mind works. Maybe if you use the nasal pillows in your ears they will work better for you. I think you're wired different than the reat of us.

By HOW, or by THAT it works?

I certainly hope so. The world would be a sillier, and much more depressed place if more people were wired like me.

Certainly, I think I was wired differently in the sleep study. I haven't heard of anyone ELSE having electrodes placed on their genitalia.

Oh, wait, I'm confusing my sleep study with my CIA interogation.

My bad.

Maybe the sleep tech was trying to prevent your nocturnal genitalia bruxation.

OK, that's the hardest I've laughed in quite some time!

Thanks!

Liam, who should have recognized the telltale signs of chafing.

Your first clue was when they said drop your drawers instead of lean your head over...

C-Flex achieves an IPAP equivalent pressure even long before expiration is complete. That elevated "positive expiratory end pressure" accounts for more efficient CO2 washout than had lower EPAP pressure been maintained during the entire expiratory cycle.

On Edit: I should have worded that for everyone... not just tech-genius Muck (who would have no problem with my inability to expresss myself clearly). Here's what I should have said: "C-Flex boosts the pressure at the end of exhalation, and that happens to help chase CO2 away more efficiently. Sorry!

That kinda makes sense. As the Cflex number was higher, it took longer with the higher number than the lower number to flush the mask out. I would suspect that is due to the greater delay in climbing back to the prescribed pressure...

Again, my situation is different as I am a full face mask user... Someone using pillows or a nasal mask is going to have a different result as there is less air volume in those masks than in a full face mask. Regardless, I am glad I have the feature to turn on!! Can not imagine not having it now.

Numerically higher C-Flex comfort settings yield lower EPAP pressures and less efficient CO2 washout rates. Numerically lower C-Flex comfort settings yield slightly higher EPAP pressures and slightly improved CO2 washout rates. The CO2 washout rates are adequate and thus inconsequential for most patients regarding all three C-Flex settings.

Rather, a subjective preference toward perceived comfort ends up determining C-Flex setting for most patients. My hunch is that higher C-Flex settings likely helps some borderline aerophagic patients with their bloating.

Yeah what he said!


I will have to try the higher setting and see if it helps blowing up like the michelin man
