Why higher AHI for Ultra Mirage FF mask than Swift?

Is there any reason why I am getting much higher AHIs with Ultra Mirage FF mask than my Swift? Is it cause by the 420S reporting more leaks as Apneas and Hypopneas with the FF mask than the Swift?

bigheadr,

I will be watching with interest the responses to your question. I too have noticed a higher AHI between the same masks! I average .5 to 1.1 with my swift and 1.9 to 2.2 with the ff mask. Wondered if it was only me. I do not use the same machine as you so I don't think it is the machine making the difference. I suspect it has to do with the fact that the air is "forced" into your nose with the swift and has to be "sucked" in with the ff. Just my quesstimation. Hope someone can give us an answer.

I get better results with an Activa than a Swift mask, but my results for ME with a full face mask are so scarey that I won't even consider using a full face mask anymore. I would rather skip CPAP than go with the results I get from a full face mask.

My experience with a full face mask is NOT the norm, but knowing cpap, I am probably not unique either.

I wake up with a pounding oxygen deprivation headache when I use a FF, and that includes when I can get one of those hovercraft to actually seal. The bad results are confirmed by software.

see disclaimers below....

I can't speak for any other masks as I've only had the one listed below (ResMed Ultra Mirage FF). I do weekly averages (daily) and my AHI average for the last seven days (from MyEncore) is 0.3. The highest one was 0.5 and have had no apneas during that time period.

Do I like this mask? YOU BET!!!

I guess I lucked out with my first (and only) choice.

Once again, only proving that what works for one person doesn't for the other.
I get better AHIs with my Swift than with my Activa, a pretty signficant difference. That's a good thing, too, since my Swift is my favorite mask out of any I've used so far. And I think Mommaw had a point about the air being pushed into the nasal passages rather than having to suck it in. But, again, it's not in all cases that nasal pillows will give you better results. Look at Snork.

I was told that full face masks leak more than other masks. Perhaps it is due to the larger area.

Well, I was just surprised by looking at last night's data. I just got a new Medium Ultra Mirage FF Mask from my DME yesterday exchanging my large and the Medium loaner. Last night, I had one of the lowest nights ever. I had 3.4 AHI and 2.3 Acoustical Vibration (snoring) index even without an APAP. Now, I hope that I can continue it another night. It must be the seal didn't create any leaks. I can't wait to try the 420E when I get it and see if it gives me more consistent numbers.

The reason the full face masks leak a little more than nasal masks is becuase there is a bigger surface area. A lot of time it takes more pressure to get the same results with a fuill face mask then with a nasal mask.

Which is why I call full face masks a "hovercraft"

Full face masks do actually leak a little more
