C-Flex: technical term or cpap slang

[carbonman]

Just for my own edification, please.....

there is:
cpap pressure 4 to 20cm
exp. I use cpap set at 13cm.

cpap pressure 4 to 20cm w/cflex 1,2 or 3
which provides a reduction of 1,2 or 3cm from the set cpap pressure on exhale
exp. I use cpap set at 8cm w/cflex set at 2

apap pressure set in increments between 4 and 20cm
exp. I use an apap set at a min. 8cm and max.12cm

apap pressure set in increments between 4 and 20cm w/cflex of 1,2 or 3.
exp. I use an apap set at 12.5-17cm w/cflex set at 2.

There is no such thing as a setting of cflex pressure 9cm or cflex pressure 12.5cm.

The use of the term "cflex pressure 9cm" is at the least, misleading,
and at the worst is ignorant and unprofessional.

Never heard it put that way and if I did my thought would be "he doesn't know what he's talking about". Cflex is not a pressure but a process patented by Respironics.

You experienced this somewhere?

I'll take that as a yes

Edit:
I read the 1st part of your link, I did not have time to read it all. However, My Q? is withdrawn.

We talked about this sometime ago. I somehow feel responsible for your misfortune. Perhaps I didn't adequately describe what to expect?

You will meet with extreme resistance if you try to change their ways.

It is a scary world we live in.

Don't even bother with Q?'s like -
Which mask?
Which machine?
What is your pressure?
They usu. think they have a very good DME too.

How would you like to meet one at the next intersection? Put your seatbelt ON.

Respironics' C-Flex feature does not provide an exact number of cms of reduction in pressure when exhaling. The C-Flex settings of 1, 2, and 3 do not correspond to numbers of cms of drop in pressure for breathing out. The actual amount of pressure reduction C-Flex gives varies depending on how forcefully the person breathes out.

ResMed's EPR feature gives an exact number of cms of pressure reduction when exhaling. ResMed's EPR settings of 1, 2, and 3 do correspond exactly to that number of cms of drop in pressure when breathing out.

RIGHT ON RESTEDGAL. GOOD TO SEE SOMEONE KEEPING IT REAL.
I HAVE BEEN USING CPAP BY BOTH RESMED AND RESPIRONICS FOR 3 MONTHS NOW, AND I DON'T HAVE OSA. ATLEAST NOT ENOUGH TO QUALIFY. I HAVE MY PAP PRESSURE RANGE FROM 7-15. EVERYONE IS DIFFERENT OBVIOUSLY, BUT I HAVE NO PROBLEMS WITH EITHER CPAP. I FIND THEM BOTH COMFORTABLE, BOTH HAVE A PERK OR TWO THE OTHER DOESN'T, BUT TO SIT AND COMPLAIN ALL THE TIME ABOUT A MACHINE THAT IS GOING TO SAVE YOUR LIFE MAKES NO SENSE TO ME. BOTTOM LINE IS, YOU CPAP USERS WHO ARE HAVING PROBLEMS NEED TO SUCK IT UP. I KNOW THERE ARE QUITE A FEW OF YOU WHO WILL JUMP MY CASE, BUT I DON'T CARE. HAVING THIS SITE AS A HELP, ALONG WITH PROFESSIONALS AT YOUR LAB AND DME SHOULD GET YOU THROUGH. THERE ARE SO MANY WORSE DISEASES TO HAVE WITH MUCH HARDER TREATMENTS TO GO THROUGH THAN CPAP. I PERSONALLY HAD THREE HEART SURGERIES, AND HAD DIFFERENT TYPES OF TREATMENTS FOR IT FOR 10 YEARS BEFORE I FINALLY WAS CURED. IF I HAD A CHOICE OF WEARING CPAP OR GOING THROUGH 1100 PLUS VISITS TO THE ER IN TEN YEARS, I WOULD SETTLE FOR A CPAP. I HAVEN'T WRITTEN HERE IN A LONG TIME,AND THE REASON FOR THAT IS THERE ARE QUITE A FEW BELLY ACHERS, AND THEN THERE ARE SOME OF YOU WHO ACT LIKE YOU ARE BETTER THAN THE PEOPLE TRYING TO HELP YOU. INSTEAD OF EMBRACING TREATMENT, YOU ARE CYNICAL AND TRY TO FIND FAULTS WITH YOUR DME, OR LAB. WELL OVER HALF OF THE PEOPLE WITH OSA HAVE BROUGHT IT UPON THEMSELVES, AND THEN THEY ARE GOING TO JERKS TO THE ONES WHO ARE TRYING TO HELP? WHATEVER. TO THE OTHER HALF OF YOU WHO DIDN'T BRING IT UPON YOURSELVES, SAVE YOUR COMMENTS. I DON'T NEED A LIST OF PEOPLES BMI'S TO PROVE THEY DON'T DESERVE OSA. NOBODY DESERVES OSA, BUT IF YOU ARE OVER 100 POUNDS OVER WEIGHT, WHAT DID YOU THINK WAS GOING TO HAPPEN IF YOU GAINED THAT AMOUNT OF WEIGHT? ITS TIME FOR PEOPLE TO ACCEPT RESPONSIBILITY FOR THEMSELVES, AND STOP PLAYING THE BLAME GAME. NOW GO AHEAD AND BLAST ME FOR PRACTICING MY FREEDOM OF SPEECH. I KNOW HOW NAUGHTY I AM FOR BEING HONEST. I REALIZE THAT ONLY PEOPLE WITH OSA SHOULD BE ABLE TO TALK TRASH ABOUT HEALTHCARE, NOT THE OTHER WAY AROUND BUT THATS MY RANT. I AM FINISHED WITH THIS WEBSITE, SO THERE WILL BE NO POINT IN ASKING ME ANY QUESTIONS. IN FACT, ANY LAME ATTEMPT AT ANY TYPE OF COMEBACK WILL BE VIEWED AS A COWARDLY MOVE OF PICKING ON SOMEONE THATS NOT EVEN HERE. WHICH I BET THERE WILL BE ATLEAST 3 OF YOU WHO WON'T BE ABLE TO RESIST. SO GO AHEAD AND START CRYING. SOMEONE IN CYBER LAND WHO IS AS BIG OF A CRY BABY AS YOU WILL HOLD YOUR HAND AND STROKE YOUR HAIR AND TELL YOU ITS NOT YOUR FAULT YOU WEIGH 390 POUNDS. I BID YOU ALL FAREWELL AND GOOD LUCK.

Sheesh! Can you imagine how much gas money you would have saved if they had only set you up with a room on the ten-year discount plan instead?

That works out to one ER visit approximately every three days. At the very least all the other ER regulars---the ones wearing clinical outfits---should have set up your favorite recliner chair out in the ER waiting area. VIP shuttle service would have been appropriate if not expected after your first few years down at the local ER as well. I suppose an ER habit like that is better than having spent all that time down at the local bar.

IN FACT, ANY LAME ATTEMPT AT ANY TYPE OF COMEBACK WILL BE VIEWED AS A COWARDLY MOVE OF PICKING ON SOMEONE THATS NOT EVEN HERE.

Well, I can't rightly dispute your claim of having visited the ER every three days or so for ten years. But I think there's room to seriously question your factual claim of just how you will view upcoming message board events...

Okay... Humor some more polymorphic thinking if you may:
If you're not here to view any of the ensuing events... then how can you possibly take any view---cowardly or otherwise---of those same completely unviewed events?

Makes no sense...

Being serious for a moment, I hope you have a petroleum accident, catch yourself on fire and there's nothing to douse the flames except battery acid.

Have a Muffy Day!!

I can imagine someone referring to "the amount of pressure delivered with C-flex on" as the "C-Flex pressure" in an oral-shorthand sort of way.

I can also imagine a person who is trying to direct the attention of a room full of uneducated people to a particular number on a piece of paper that happens to be located next to the word "C-Flex" (then a space) then the word "pressure" using the term "C-Flex pressure" to direct the audience's attention to the correct spot on the paper in front of them.

But I can also see how someone who knows what C-flex is would be misled by someone wording things that way.

To illustrate: We use the term "deep sleep" around here sometimes. To some sleep people, that might be considered a highly misleading way of putting things. "Deep" in what way? Deeper than what? Which part of the sleep cycle are you referring to? Anything beyond Stage 1? Are you including REM? Do you mean when someone is difficult to awaken? Do you mean restorative sleep? What? Knowing more about sleep makes some terms more confusing in their inexactitude. Yet, in context, most of us know what the writer in a forum is getting at.

In other words, I think maybe the problem at the A.W.A.K.E. meeting was that you knew about "C-Flex," if the presentation was aimed at people who do not.

RG, thanks!, for the clarification between the two products.
My education continues.

So, if it is a variable amount, how do you define "c-flex pressure 9cm"?

[Wulfman]

NOBODY DESERVES OSA, BUT IF YOU ARE OVER 100 POUNDS OVER WEIGHT, WHAT DID YOU THINK WAS GOING TO HAPPEN IF YOU GAINED THAT AMOUNT OF WEIGHT? ITS TIME FOR PEOPLE TO ACCEPT RESPONSIBILITY FOR THEMSELVES, AND STOP PLAYING THE BLAME GAME.

Did it ever occur to you that those peoples' weight gain was CAUSED by their OSA?
And, there are other factors that can prevent people from getting enough air into their system while they sleep besides airway "collapse".......like nasal passage restrictions.

Oh, I forgot.......you're not going to be around to read the responses......

I have never heard of clinicians referring to "c-flex pressure" instead of "CPAP pressure" either, carbonman.

However, clinical ignorance wasn't my first thought---since I don't think it's likely that any clinician can repeatedly observe C-Flex during PSGs without fully understanding that it's specifically expiratory-phase pressure relief. C-Flex is not without unintended side effects across the patient population. Some people find C-Flex wonderful while others find it uncomfortable. There are a few, like me, who experience more aerophagia because of C-Flex. And there are some, like WillSucceed, who experience breath stacking because of C-Flex.

On that note, my first guess was that these clinicians wanted to clearly document C-Flex titrations---should they ever perform historical reviews toward understanding treatment patterns (related to efficacy and/or unintended side effects). Thus, it would seem potentially advantageous to clearly document the various treatment modalities: "CPAP", "C-Flex", "EPR", "BiLevel", etc. Follow up analysis or epidemiology related to those various treatment modalities then becomes much easier. Just a wild guess on my part.

My other guess for those repeated appearances of the term C-Flex was that a cozy little deal from Respironics had been arranged----the equivalent of a C-Flex advertisement. Drink Coke... Breathe C-Flex... Got Milk? ...Got C-Flex? That kind of deal.

I bet a roll of blue mouth-tape we haven't really seen the last of polypsychoman...

But, more to the point, it seems obvious to me that the term "C-flex pressure xx" refers to a setting of xx with C-flex turned on.

Carbonman: "So, if it is a variable amount, how do you define "c-flex pressure 9cm"?"

A pressure which modulates due to several unknown and changing variables, but with a peak of 9cm/H2O.

(For the record, "9cm" is a linear distance, not a "pressure". I'm surprised a stickler for accurate terminology would use such a term!)
