Newbie - Is my pressure too high?

[djhall]

Is the Escape really that bad? Is it just that it doesn't capture data or are there other known problems with it?

Yes, it really is that bad, even though the problem is only that it doesn't capture data.

With an Escape you could strap the hose on every night, get far less than effective treatment from it, and have absolutely no idea since you don't have any machine data to analyze and you don't know what a proper night sleep should feel like anyway. Or you could be like a recent addition to this forum whose doctor sent her home with a prescription for 17cm pressure which prevented her from being able to sleep with the CPAP. Analysis of the machine data revealed that she didn't actually need to be set higher than 10 to get great results and she could sleep comfortably at that pressure. That disaster turned into a success, but only because she had a data capable machine.

In a world where the doctor gets your prescription set optimally and your needs never change, data capable machines wouldn't be essential for good therapy and there would be nothing wrong with an Escape. Unfortunately, that rarely happens.

Does anyone remember if the algorithm for the AutoSet is different for the Escape Auto since the Escape auto doesn't flag centrals?
Resmed has moved all their web pages and there was one page that showed a comparison between both models and there was more of a difference than just the limited AHI that the Escape Auto offers.
I can't remember exactly though but it seems like the Escape Auto lacked something in the technology part....but I can't swear to it since I can't find that page now.

Thanks, everyone. I just updated my profile.

Yes Its really that bad.. It is worth every effort you make to get it switched out now..

I see you have the same machine I do. What do I need to get a report out of the SD card? Do I need a adapter for the SD card?

If your computer has a slot for a SD card...no you don't need any adapter as long as the SD slot is functioning.
If your computer does not have a slot then yes, a little card reader/adapter is needed. Cheap generic will work so you can connect to a USB port.
Sometimes the SD slots are not seen on some computers. My laptop has one but if I hadn't ask about it I never would have known it.

Then you need software...I have links in my signature for Sleepyhead which will work with the PR S1 760 machine.
There is also Encore software and I can help with that if you will send me a private message but please include which Windows version you are using...with the new Win 8.xxx it makes a difference what will install and what we can do if we need to do a work around.

Is this the comparison chart you're looking for? http://www.resmed.com/int/products/prod ... nc=dealers

Yes, thank you.

The S9 Escape Auto does not have the Enhanced AutoSet Algorithm...since it doesn't detect or flag centrals it works in the old S8 algorithm instead of the new S9 algorithm.

Yes, thank you.

You're welcome. Wow -- so if a person started throwing centrals early in PAP therapy they would have no way of knowing with the Escape Auto?

[Pugsy]

Pretty much. I don't know what was done with the centrals with the not so enhanced firmware....did they just not get flagged and not counted anywhere or did they get lumped in the OA/hyponea basket?
I don't know and what little I did know about he old algorithm I have forgotten most of it.

Granted the chances of developing a problem with centrals is small but it isn't rare by any means...and that's why I harp on event categories so much and not AHI itself without knowing the breakdown.
With machines that do flag centrals if the AHI is ice and low we can infer not many centrals but I don't remember what the old algorithm did with ResMed centrals....don't know that I was ever told.

I know that in the M series machine from Respironics they got dumped in the OA/Hyponea basket...I got that directly from Respironics.

A CA is going to meet the criteria for scoring an apnea: The flow rate will be decreased by at least 90% for at least 10 seconds. It's just that with the old algorithm there was no way to figure out is a scored apnea was a central apnea or an obstructive one. So anything currently scored as a CA on a Resmed S9 AutoSet/Elite would certainly be scored as an apnea on a Resmed using the older scoring algorithm. And since the Resmed S9 Auto Escape does NOT have the new auto algorithm, it's a reasonable bet that it also does not have the FOT algorithm that the S9 AutoSet and Elite use for distinguishing between CAs and OAs. So CAs would count in the AHI, and if the AHI were broken down into an AI and an HI, the CAs would be part of the AI.

As I recall, the old Resmed algorithm increases pressure in response to all apneas when the pressure is AT or BELOW 10 cm, on the assumption that at low pressures, the probability that the apnea is an OA is significantly greater than the probability that the apnea is a CA. And the old algorithm does NOT increase the pressure for any apnea when the pressure was ABOVE 10cm, again on the assumption that by the time the pressure gets to be 10cm, the probability that a particular apnea is a CA is no longer small enough to ignore and the difference between the probabilities of the apnea being an OA vs. a CA are no longer significant.
