Can we tell from the Silverlining software what stage of sleep the data is representing? Data tell us a lot, but not that? Also O2 sat's, I am assuming it doesn't do that either?

Txs.......

You assume correctly.

I suspect you'd need to have an O2 device on your finger and some EE-lectrodes on your head to tell the other things. I'm pretty amazed at what it CAN tell you through its little tube. I keep trying to convince myself to believe it!

My doc said he has overnight O2 home-recording equipment. If you are specifically having an issue, maybe you could have that sort of thing done and look at the results alongside the Silverlining data for the same night. That could be interesting.

Duh. I just looked at the "Oximetry on RemStar..." thread.

Maybe we can figure out how to get pulse oximetry over the internet by measuring O2 with your finger on the mouse and sending the data so some central server... I guess it would be sort of hard to sleep with your finger on the mouse all night (Liam, stay away from this).

I've been on this board too long, when I read your thread, and said to myself, "now what would Liam say to this one, re: finger". I'm not going to go there, but we do need a laugh now and then.

Txs for into, I didn't think my little 420E could give us that much,re O2 sat's, but it gives me in my "opinion only" enuf daily data to know my ap's, pops are just about zero, so that's good enuf for me!
With this software I can even match up the leaks (mask ones that is) and try to figure out a time when I can recall during night, shifting the mask, getting up, detaching, etc. this knowledge is certainly better than never knowinghow I'm really doing, or worse yet, going for another titration study. Ugh.

Its a

I wouldn't give anyone on here the finger. That's just rude. Well, maybe that one "guest", but other than that....

Gail,
I can certainly see differences in leaks with different masks showing up in the data. For me, the Breeze is the lowest and most consistent. I've been trying to get used to the Swift, but I get a little higher and less consistent leak rate. My UltraMirage (nasal) gives me the least consistent leak rate (mustache...), but it is the quietest mask I use. I haven't been able to correlate times when I know I was awake with the data. In the three weeks I've used the 420E, I've recorded 3 apneas, 4 ap/CA, 37 "pops" and 9 pop/FL. Looks pretty good to me! It hardly jumps off of my low setting of 6.

My only wierdness is inconsistent "runs" (Liam, don't you dare). I've ranged from 182 to 18 per night. Hmmm...

UKWIS,

The leak rate for each mask will incorporate the built in exhaust requirements. Based on the flow pattern for each interface the amount of "built in" leak will vary as required to clear the Co2 from the chamber. As long as your leak graph stays out of the "large leak" range the machine is able to compensate for the leaks.

So, if I just keep big clumps out of my mustache, it should be ok, right wader?

I did have a problem with pressure runaway one night using my nasal mask. I thought it might be leak related; -SWS thought my breathing pattern was triggering an over response. I switched off IFL1 on his suggestion and all seems fine now. It did make me a little reluctant to use the nasal mask with the auto machine after that, so I've mostly been using the Breeze and Swift. The nasal mask is sooooo much quieter...

UKWIS,

I have seen pressure run-ups related to mouth leaks, but these are large leaks. I had less of this with the 420E than I've had with the REMstar auto.
Regarding the nasal mask, since I've been using the Swift I think I would have a hard time going back to the Activa. I tried it for a nap the other day and had forgotten how cumbersome it is.

Wader,
My Swift is making me deaf... The UltraMirage is much quieter. The Activa huffs and puffs alot more with the 420e than with my Remstar/Pro... Tweech Hisown.

I thought it was me, that the Swift is noisier. I use a ''white noise'' sound machine in the bedroom and it sort-of masks that problem. But the noise from the 420E of my breathing and hearing the machine sound somewhat like it's breathing ''with'' me is disconcerting. I listen to the sound machine and tune it out. Many people can't handle the noise sound machine, so I can see where these masks/or/machines do have their own distinctive ''noises''.

I am glad someone mentioned the run-up, my 420E sometimes does this, when I disconnect for ex. to go to the b.room, when I come back and hook myself back, the 420E takes off so I wait and then it comes back down to my bottom pressure. Which for now is 5, any ideas on why this run up?

thanks........

BOY!

You'all must be WAY! more sensitive to noise than I am. I hear all the noises you are talking about, but they just don't bother me. I guess maybe I have become immune. I live in a noisy environment... things going on twenty four hours a day.

Sometimes if I breath deeply I can hear my remstar making the breathing sound, but it is completely covered by our hepa filter on low... White is not bad, covers up house creaking etc...

UKnowWhatInSeattle · Post by **UKnowWhatInSeattle** » Wed Mar 02, 2005 5:20 pm

Yes, I freely admit to being a noise sissy. Although in the city, I live in a quiet neighborhood and the only thing making noise in the house is one of the cats (and sometimes my wife delicately snoring). I seem to be very sensitive to the noise coming up the air column from the mouth of the beast through the hose. I notice a huge difference when the humidifier is not in-line also. Earplugs don't do much for that...
