A Flex vs. C-Flex

I am a new CPAP user and am currently using a System One (DS250) which I have since learned doesn't allow me to check AHI or waveform data only compliance data.

I am going to buy my own unit as I need another unit for travel and have considered the PR System One APAP. The machine I currently have has C-Flex as exhalation relief. How is C-Flex different from A-Flex? Anyone made the switch from CPAP to APAP? Worth it?

My goal is to get a better night sleep which I have started to do but have noticed the sleep position changes how refreshed I awaken in the AM. I mentioned this to my sleep doc and he said there will always be good nights and bad nights and that he didn't seem to feel he needed to make a pressure change.

Welcome to the group.......

By all means purchase the auto AFLEX/CFLEX data capable machine. Get the software for it....and take charge of your own therapy. You'll learn as you go along....and you'll find it easy to tweak your system for best results AND best comfort. It isn't "rocket science"...

The M-Series machine I use offers CFLEX and AFLEX.....and I prefer CFLEX....probably because my spare machine (the one I started out with) offered only CFLEX. You'll determine which exhaled pressure relief you like the best....you may like AFLEX....or you may like CFLEX.

You're off to a good start....and you'll do well.

Thanks for the info. I am looking at the System one with APAP - I figure the humidifiers are the same as are the hoses so I will have a spare of each if needed. I should be able to come up with the cash by next month. My next appt is the 24th where supposedly they are checking my compliance so maybe it is best to finish the next 2-3 weeks with the same unit they gave me.

I have learned that if I sleep on my back I usually do okay in the AM. If I sleep on my side things go down hill the next day - might be a leak or not enough pressure. Given the doc's response I think it is best that I get an APAP and monitor my own therapy with software.

Does the software on your signature line allow for AHI data review? How about waveforms?

Thanks again!

Go for the "top of the line" System One Auto with CFLEX and AFLEX. The software will allow you to do a "poor man's titration" every night if you want to. Operating with software is the absolute best way to go.

The M-Series that I run is the previous model.....the one before Respironics was bought out by Phillips. My equipment is about 4-years old now.....and like most things "electronic", it's technology is a little dated. I'll run the M-Series equipment for another year or two, then go for the System One....which might be "System Two" by that time.

do you know which system one APAP has both a flex and c flex? i have been checking on and cannot find one that states that it has both forms of exhalation relief.

Alex,
Get the Auto with AFLEX... description says that it also has CFLEX

Thanks. Do you know if Encore Viewer also show trend data for AHI, snoring, leak etc?

Yes, it does.

There is also C-flex Plus, another option with the newer Respironics. I started off using C-flex Plus, but last week switched to just C-flex, and it seems to have been a move in the right direction, in my instance.

i wish they would have given me the APAP machine up front. now i have to pay a lot out of pocket to get it.

I have in the last month switched over after 8 years using CPAP without A Or Cflex facility, to a Devilbiss Intellipap APAP.
My cpap pressure was 9. I set the apap to 8-12 and the equivalent of a/cflex turned on.
Found my 90/95th around 10, and AHI's 5-8 over about a week. Didn't need any software to obtain these readouts with the Intellipap.
Turned off the a/cflex and 90/95th was usually 8, AHI's under 2, sometimes under 1. I have reduced the lower pressure to 7 and most mornings the 90/95th is 7 or 7.5.
Don't know why but the flex seems not to be good for me.
I never had any problem on exhale with cpap, so I guess that is a feature I don't need.

Buy the good equipment out of pocket....keep the lower quality machine as a spare.

They don't want to give you top of the line equipment.....because they make fewer $$ if they do.

Hi Countman, Sounds like you are still renting. If that's the case you should request the Auto Aflex from your DME then get a cheaper backup out of pocket. The insurance pays the DME the same if you get a cheep no data cpap or the top of the line. I switched machines 2 months after I started. What a difference. The DME lied to me so I went to a different DME and got the machine I wanted (actually for less out of pocket) . As long as you are renting you can divorce yourself from a DME and their machine and go somewhere else. Good luck

No Sleepyb, I am in Australia and have to buy/pay for the cpap/apap myself. Did in fact buy it from USA. Only cost me about $600, equivalent machine here would have cost $1500.
Very happy with the Intellipap and the the data it provides, but could have gone for the previous model without the flex as it turns out.
