Today I received the Hybrid mask. It was simple to put to use after cleaning and drying. I put it on the DS510 M-series A-FLEX unit with settings of 9-cm/H2O and 13-cm/H2O. FLEX resistance was set at 2. The humidifier was clean and empty, acting only as a passthrough air chamber.
Though the headgear is too confining and will take some getting used to, I managed to nap prone with it on for about 3-hours. I like to test any mask during day hours, before I attempt to have a night of compliance with it.
I woke feeling very ill. I pulled the mask off and stopped the unit. A major migraine was making me nauseous, my vision was very skewed, my hearing was tinny and I was dizzy as a kite in a torando.
I sat upright, and seconds later I passed-out and fell back onto the bed. I woke again about an hour later with the headache still evident but lessened enough to be able to walk. I still feel very bad, but my vision and hearing appear normal now.
My current masks are a Comfor Curve, OptiLife and the new Hybrid. My previous masks were all nasal cup or pillow styles. This is my first experience with a hybrid full-face mask. I won't even consider trying a true FF mask again -- well, I pray that I don't have to.
I suspicion that for some reason I was rebreathing part of my exhaust during portions of that 3-hour trial run with the Hybrid mask. It is too late, and I'm too recovered now, to worry much about getting pure oxygen. Instead, I used a Pro-2 C-FLEX with a Comfort Curve mask and raised the pressure to 14-cm/H2O to push my breathing while awake and upright, to boost recovery.
I checked my stats in Encor Pro and saw that the unit cycled briefly several times as though mask disconnect had signaled shutdown. I always set the Mask Alert and Auto-Off due to my penchant for pulling masks off in my sleep -- despite that gaining mask tolerance and the addition of aroma therapy are helping with that to a great degree.
The other thing I was unaware of before buying the Hybrid mask is that, the design vent for that mask at 10-cm/H2O is about 48-LPM. That is about double the design vent LPM of masks I normally use.
NOTE: During sleep I experience unpredicatble periods of very shallow breathing, for unknown reason(s), that are seemingly apart from OSA byproduct ailments.
Could it be that the A-FLEX limit pressures were set too low to use the Hybrid mask safely?
Would raising the pressures in A-FLEX alleviate the risk of rebreathing carbon dioxide with the Hybrid mask?
Will it be necessary to switch to C-FLEX to use the Hybrid mask without risk of rebreathing my exhaust?
Yes, I am still fuzzy-headed, 6-hours later, and not thinking clearly yet.
Any viable suggestions or experienced guidance would be greatly appreciated.

Last night I checked and rechecked the Hybrid -- it was (is) 100% complete and functional as used yesterday during the 3-hour trial run. I should note, that ivory soap was used to pre-clean the mask right out of the package, and rinsed really well and dried thoroughly before assembly and use.
As a test last night, I raised the A-FLEX pressure from 9-cm H20 to 11-cm H2O and from 12-cm H2O to 14-cm H2O and used the Hybrid mask as it was when I removed it from my face yesterday afternoon at the lower pressures.
While the headgear being tight enough to get a firm seal isn't yet comfortable for me, I slept rather well overall. I woke this morning without mishap or ill feeling.
My night-sleep 90% AutoCPAP pressure, at the increased pressure limits, was equal to the lower set pressure of 11-cm H2O throughout the night. I realize that may not be optimal, but it occurred with the Hybrid at the increased pressure settings.
But, there were zero (0.0) Sleep Therapy Flags during the night, a first ever for me, even on straight CPAP or C-FLEX - NR: 0.0, F: 0.0, OA: 0.0, H: 0.0 and VS: 0.0 for AHI 0.0 for the night. I did not experience aerophagia or other symptom or discomfort, and woke fairly refreshed considering my norm even following my better therapy nights with other masks at lower pressures mentioned above.
Though, the Hybrid design vent is really high, and I had a very good seal, my leak numbers were huge -- Average Leak 93.5-LPM for the night. The Hybrid design vent is about 52-LPM at 11-cm H2O. I don't understand where the other 40-LPM-plus was going. I never felt it leaking in any of my routine wakings, and each time went back to sleept quickly after checking the mask.
I am baffled, and not sure I should continue using the Hybrid on A-FLEX... but I sure like the 0.0 Sleep Therapy Flag numbers resulting in AHI: 0.0 for the night. Still, it's sort of scary though.

Personally, I wouldn't give you $.29 cents for that Hybrid interface especially when used on a auto-titrating machine.Nodzy wrote:Last night I checked and rechecked the Hybrid -- it was (is) 100% complete and functional as used yesterday during the 3-hour trial run.

Yes, that interface has a high intentional leak rate, way too high in my opinion. When leak exceeds 75L/m on that machine it will begin shutting down and it starts by dropping pressure by 2 cm. Eventually it may even shut off.
That leak will show up on your EncorePro reports as a Large Leak. As for the AHI=0.0 and the other zero data? That is data is skewed also from the massive leak. Not only does the machine begin shutting down with leak over 75L/m it stops recording data.
While that Hybrid may stop you from mouth breathing, it totally hoses an autopap in my opinion, the reason is the autopap needs to "read" your breathing events then respond.
Look at that interface carefully, air flow comes in via the mouth interface then exits via the pillows to the nose, if you have an apnea event, it has to "sense" that obstruction in the reverse order of flow, meaning it has to detect the obstruction at the back of your throat, thru the pillows, back thru the mouthpiece, finally down the hose to the machine where the sensors is located.
Basically, the sensitivity of the machine to respond is diffused from the design of the mask. So if you combine the harder ability of the machine to read your events with a high intentional leak rate, a leak rate higher than the machine can compensate for, that all adds up to bad therapy.
I'd bet money if you used a nasal mask you AHI data would return back to normal values seen and you would feel a whole lot better.
if your 90% pressure was shown at 11 cm before, you can set your Auto:Min pressure to 9cm if you want and put the Auto:max at 15cm and that should work fine. Evaluate your AHI, if you have the reporting software, look at OA and get that down around 1.0 or less then observe the HI data, keep that down below 5 or don't let that score combined with the OA exceed 5. HI will begin to drop once you get the pressure where OA is lowest, once OA drops to its lowest level HI will begin to drop.
I don't think there is anything wrong with your machine other than you are using an mask interface with leaks exceeding what the machine can handle.
You felt bad and dizzy and all that from the mask not the machine, you were most likely rebreathing your own exhaled CO2 when the machine shut down.
Mask Alert should be On or enabled, Auto:Off should be Off or disabled. That mask may be fine on CPAP, CPAP doesn't need to "read" your events or require feedback to function, an autopap does, my opinion is that mask is not very good for use with that machine.
I'd toss out the mask before I toss out the machine, there is a reason that interface is the most heavily traded used mask. When you add up all those that have tried it and those still using it, I bet the number that have tried it vs number still using it is much greater.
I think the Quattro is also a lousy interface, but I bet you would do better with it vs the Hybrid.
someday science will catch up to what I'm saying...

Thanks for the input -- much as I suspicioned. Certainly, I won't trash the machine -- it offers five (5) modes of therapy and is a very versatile unit -- CPAP, CPAP w/C-Flex, Auto-CPAP, Auto-CPAP w/C-Flex and Auto CPAP w/A-Flex.
One reason that I bought it is, should my circumstances and needs change the mode of the machine can be changed to suit. That is, unless I would at some point need a BIPAP or other machine even more sophisticated to assist my respiration when sleeping.
Yes, I agree with the assessment of leak. I couldn't find the stat's on the design vent LPM of that mask prior to purchase, and bought it in the effort to try to get my mouth breathing and tunnel venting under control. Too, I assumed that the design vent LPM would not be too large, or be a problem with A-FLEX.
Obviously, the Hybrid mask design vent LPM is more than the Auto A-FLEX can deal with while trying to assess and react to me.
I'm still concerned to know where that other 40-LPM leak was going, because the mask was not leaking at the seals, and the design vent at 11-cm H2O was about 54-LPM.
The mask literature, if it is NOT compatible with A-FLEX, should state in bold lettering that the Hybrid is not suitable for use with A-FLEX or a competitive brand's similar technology.
Of course, it could be that Auto-BIPAP, which the literature does state that the Hybrid is suited for, may at some point be my best target. I can imagine that wallet ache.

Snoredog,
Thanks for the input. I agree. Respironics doesn't want to encourage sales of other mask brands, as the other mask brands don't want to encourage sales of xPAP's they're not financially aligned with. Too, there could be liability and legal issues that my non-litigious mind has not stepped down low enough to see.
Minutes ago I found several places online selling M-series A-FLEX and Hybrid mask combo packages, with one being...
http://www.thecpapshop.com
and the product link is....
http://www.thecpapshop.com/product_page ... ctCatID=22
Obviously, some think they're a decent match even if they aren't with the unit in A-FLEX mode, or Auto mode.
I will experiment with mine a bit, and possibly regress to CPAP w/C-Flex, Auto-CPAP or Auto-CPAP w/C-Flex and try it in each mode. The only reasons I chose A-FLEX were for comfort, to resolve taking the mask off in my sleep, and an attempt to achieve better compliance and lower Sleep Therapy Flags and overall AHI's.
There's a great likelihood that with the mouth problems curtailed, I might find a match with the Hybrid in a less sophisticated xPAP mode. Then it's just the hassle of finding the best pressure settings despite the Hybrid's large design vent LPM and my sometimes widely varying needs per night. It's worth a try to resolve the mouth problems with one mask applied to my face, without added chin straps, mouth-taping or a combo of chin strap and taping.
<sigh> I'm still waiting for delivery of that uncomplicated life I ordered 35-years ago.

Some improvement of the Hybrid mask-to-me fit was achieved after gently trimming off the chin-cup of the LG seal assembly this morning. Minus the chin-cup it mainainted a more consistent seal during my brief 90-minute test. Most noticeable was the greatly improved comfort of the seal to my face, especially at the chin.
Though, the Hybrid appreared to seal really well in my first day and several night uses of it, the huge leak numbers were disappointing. But, the design vent LPM of the Hybrid at a given pressure are more then double the design vent LPM at a given pressure of the Comfort Curve and the Optilife.
I'll try the Hybrid again tonight at the current (raised) pressure settings and the M-Series Auto A-FLEX switched from A-FLEX to Auto C-FLEX mode. After a night or two of testing in this configuration, I may have to decrease the pressures if the the mask will now consistently provide its best possible seal on my face with the chin-cup trimmed off.
A stat's check in Encore Pro tomorrow will tell the tale for that stage of trying to make the Hybrid work well for me.

I have been using the Hybrid mask for one year with straight cpap, pressure 10 cm. The chin flap is removed as you did also.
As far as I can tell without a data capable machine, the mask rarely leaks. If it ever does I just need to readjust the headgear.
Innomed made a second release of the mask with a lower vent rate. I understand that this was because of the difficulties auto machines had with the high vent rate of the first Hybrid mask version.
I acquired the second release of the Hybrid mask. Visually the only difference I find is that the vent holes are smaller diameter. I do not have the manual with this shell so I can't quote the numbers of the lower vent rate.
Having contacted Innomed's excellent customer service a few times, I feel certain if you call them and explain your problem with the high vent rate, they will send you the second release of the Hybrid shell gratis.
I like to help people but I also have a vested interest in your story. I have tentative plans to acquire an A-Flex in hopes of relieving aerophagia that I get with any mask I have tried. I would like to hear how your situation plays out with the A-Flex and the second release of the Hybrid shell.
Thanks.

Rooster,
Thanks for the input and PM's. As I noted to you, Innomed is gratiously sending me a revised Hybrid mask frame. I'll update this after I receive it and try it.
Though, I have to admit, after I switched the M-series Auto from A-FLEX to Auto-C-FLEX and raised the pressures, it hasn't been too bad. Of course, I also trimmed off the chin-cup which was restricting my comfort and the mask seal.
Now it seems that the pressures are too high. But, I'm not making any more changes until the revised frame for the Hybrid, with lower design vent LPM, arrives and I test it.
Thanks again for your very helpful assistance.

you may not have the new adaptive flow hybrid. you may be able to get a new shell for free (does anyone know if they do that ?)
I think I heard that some Apria's still had the older ones ? You can always plug up ONE of the little holes with tape until you get the new shell, just make sure you have the old one first.
This is one fantastic mask. Call customer service for assistance.
