Fiddling with the mask and data results

Post by DottyG » Sat Apr 03, 2010 10:05 am

No, I don't mean I'm makin' music with the mask!

I mean that sometimes I'm taking my mask off for a second or two - maybe to sneeze or to adjust the mask a bit or even to quickly see what the heck my kitties are doing to make so much noise in the windowsill!

But, I don't turn the machine off for these quick mask removals. It'd take longer to turn it off and back on than just move the mask, sneeze and put it back on.

Am I'm screwing up my data, though? Would that create "false AHIs" or "false leak" data to appear?

Still trying to get some actual help with this (no offense to the above poster, but this didn't help with my question all that much ).

Ok, so are the rest of you turning your machines off if you have something quick happen? For instance, the other night, I had a piece of hair caught between my mask and my face. It seemed really over-the-top to me to reach over, turn my machine off, move my mask for half a second to get the hair out, get the mask settled back into place, reach back over, turn the machine on, ramp it up,...... than just quickly moving the mask and getting the piece of hair out in the half second.

have you checked the graphs in the daily report?

While in an absolute sense it would impact your results, I don't think that it would impact them in a meaningful way as long as it is as quick as you describe and infrequent. If you are concerned about it, you could compare the leak data from a night that you did this with a night that you didn't and see what shows up.

I find that I lift my mask off and replace it quickly sometimes for various reasons, comfort, adjust for leaking, sneezing, etc. It doesn't really seem to register in a significant way in the leak data.

In theory, it should register as a spike in the leak line (depends on the length of time and the sensitivity of your machine.) The machine SHOULDN'T register it as an apnea event unless it lasts more than 10 seconds (the clinical definition!)

But, in the grand scheme of things, it won't matter a bit. Compare the few seconds your mask is off with the entire night. The phrase "fart in a hurricane" comes to mind (but I would never actually USE language like that... ) Unless your machine records average leak data out to about 6 decimals, it won't even show up. And, if it DID, you could mentally ignore that occurence when comparing the data.

There isn't much that I can't do, now, w/my mask on.
Call me irresistible, but....if it is just one or two,
I cough and sneeze in my mask.
If I have an itch....I make it a Zen thing to control it
and it goes away.
I can carry on a conversation and yell at the dog/cats.
....infact, when I yell at them through my mask,
it scares the crap out of them and they mind better.
I can endure that internal rainout from my sinus', when
I do jalaneti too close to bed time.
I don't really care about the numbers, it doesn't do
that much to them and if it does, I just consider that
when I look at them in the am.

I just consider it all part of becoming one w/the mask.

I sometimes have to fiddle with my mask just after I get into bed. I sometimes wake in the night and end up fiddling with my mask then. I may have been wakened by a leak when this happens.

On my data, the next morning, it shows an apnea or a hypopnea or a cluster of either but I know what happened and why, as you do.

I just discount that and look at the rest of the data. I was awake when that happened, if only briefly, so the data, at that time, is meaningless to my therapy.

My AHI will show it and the events page will show it but I know it is meaningless. It affects my data but not my therapy.

I guess my concern is not as much what I'm going to see in the data, but what the doctor is going to see when the card is read after a longer period of time. He/she is going to notice these little blips in the data.

I may or may not remember "Oh yeah! That was the night that I had a piece of my hair caught between the mask and my face, so I had to move the mask to get the hair out" or "I remember that night! My mask wasn't situated on my face quite right, so I had to kind of fiddle with it a bit to get it blowing properly in my nose. I couldn't turn the machine off to do that, because I needed to see when it was actually blowing correctly."

I could, conceiveably, keep a logbook of such things, but that just seems like overkill to me. Not to mention, I'd have to have reams of paper and spend more time writing down silly things like that than actually getting in bed and going to sleep!

So, it does affect the data, huh? I guess the doctor's just going to have to chill with it and realize that some blips in my data may not actually be apneas after all. I don't see how this really helps him/her or me, because that means that the data is worthless! But, so be it!

most likely the doc isn't going to look at anything but compliance data - how long each night - nothing more -

but what about you? have you looked at any of your daily graphs?
