Tried ResMed Machine for First Time
I wanted to understand the difference in treatment between the top of the line Respironics versus ResMed machines, so I got a ResMed S8 AutoSet II and used it for the first time last night. I had some problems. I woke up once having pulled the mask off. And the reason is probably related to the fact that I woke up in the morning feeling much more congested than usual -- and less well rested.
Everything otherwise -- my mask, chinstrap, pressure settings, etc. -- are the same. I'm also toying around to find the optimal humidifier setting.
I'm of course not writing off this excellent machine because I had problems with it on the first night, but can anyone give me some advice about how to resolve these problems?

Mike, some people don't do as well w/the algorhythm of one brand than w/another. MOST people don't notice the difference. That being said: there has been some LIMITED literature that the Resmeds tend to produce as much as 1 cm difference in pressure than two of the other leading brands. I just can't remember which way - more or less (I know, fat lotta help that little bit of info is then) - but I can't find WHERE I read that abstract! And it was a med journal abstract.
In addtion the Resmeds and the Respironics have a different method of handling events that occur above 10 cms of pressure. I think I've phrased that right. jnk can better explain this than I can. It gets a bit technical and I've done well on my Resmeds so didn't bother my grizzled ole gray haired head w/committing the reasoning to memory - tho I do have his information saved - somewhere. dsm has also discussed this at cpaptalk. It was in a thread where someone posted that Resmeds don't respond to apneas that occur above 10 cms - which is totally misleading. The Resmeds rely on a totally different "trigger" to respond to apneas above 10 cms of pressure than Respironics in an effort to avoid mistaking a central apnea from an obstructive apnea - I think that is the gist of it. But - ask jnk to answer this one for you. I'm not a techie.
The other thing is - the setting on your humidifier. You have a larger water capacity w/the Humidaire 4i than w/an M Series Respironics. The first thing congestion brings to mind is the humidifier. You may need to adjust the setting.

interesting. I did notice throwing a lot more distilled water into the humidifier chamber of the ResMed than my good old M Series. So I guess what you're saying is that I may need a higher humidifier setting with the ResMed than with the M Series?

Mike, I use the ResMed Autoset II and being a newbie I don't have a lot of experience with other machines except the ResMed Escape. I really like my machine. The EPR setting is at a 2, my numbers are set at 8-12. My split night sleepstudy conducted at Ntl Jewish Hospital in Denver had my CPAP number set at an 11. I read the LED each morning and find that I am around 10-11 pressure most of the time. I like to use the humidity setting at about a 2 because I live in a dry climate and enjoy the little extra moisture. Do you notice how quiet the machine is?
I hope you find a machine that works for you. I sure do love mine!
Jeff, thanks so much for the wonderful review on the auto-titrating machines and how they work.

The machine is super quiet. Very nice. I will lower the humidity setting to 2 tonight and see what happens.

I cut the humidifier down to a setting of two, and woke up without the congestion, and a lot better rested. so far, i can't tell much difference between this machine and my Pro, other than a very subtle "smoother" airflow, and that it's much quieter. will continue to post observations about differences/similarities as they occur to me.

Mike, check the Articles section. You might find the interview from ResMedica regarding the development of the AutoSet of interest.

Oh, yeah. The Resmeds have Respironics beat all to heck when it comes to ease of data access and amount of data available via the LCD screen. There's just no comparison.

Judy -- I'll check out the article. thanks for pointing it out to me. On the ease of data access, my RT didn't set the machine to allow access to the efficacy data. But i think i have a few ideas about how to fix that (wink wink).

What????!!!!! An ATTORNEY not intelligent enough to be able to monitor his own data?? Or your RT was afraid you would find a way to rig your data?? *wicked grin*
Sorry. I just could NOT resist!

Here are my ResMed results for last night:
Pressure 11.8 (i have it going on Auto within a tight range of 10-12)
Leak: 0.28 L/s (i have it pre programmed for my Activa mask --- very interested in hearing about what you guys think on this -- probably nothing to worry about, right?)
AHI: 4.8
AI: 0.6
HI: 4.2

The leak is not that bad. Especially considering you're just starting w/a Resmed. It looks like you are doing pretty darn good to me. HOW ARE YOU FEELING? Better? Worse? The same as w/that ole Respironics?

Feeling pretty much the same. I've been a little sleep deprived the last few days. But that's because of choices I've made about when to get to sleep and not the machine. I'll continue with the reamed and see how things change if at all.
