Question on Resmed S8 Elite II

skjansen · Post by **skjansen** » Wed Aug 06, 2008 9:08 am

Okay, I have been using my new S8 ELite II for two nights now. I absolutely love the small profile. I do have a question about data on the LCD screen though. When I review my results for the night it gives me data for everything except pressure. On that it shows "no data". Do any of you know why this might be? Could it have something to do with the EPR? I turned EPR off the first night because I could not get used to the change in pressure upon exhalation. I think that is because my resp therapist had it set at a level 3 (which I believe means that the exhale pressure drops by 3cm) but the resp therapist really did not know what that meant so as usual I need to come here for answers. I am used to straight CPAP but I am thinking I will put the EPR at 1 instead of 3).

Let me know your thoughts. Thanks a bunch.

That has me scratching my head a bit.

I have the next model up, the Autoset II currently set to straight CPAP mode. I see the same no data message under pressure, but I assumed that it was because of being set to CPAP mode the pressure was predetermined.

In APAP mode I would have expected to see whatever pressure the machine determined was needed.

On the Elite, which is only CPAP I would not have even expected to see the item listed on the results menu.

I too would be interested to hear what the pressure results are supposed to be.....

EPR 3 is 3 cms of expiration pressure relief as you surmised. 2 would be 2 cms of expiration pressure relief and 1 would be 1 cm.

Boy! I have absolutely no idea why the Pressure doesn't show up on the LCD screen!

On my S8 Elite and S8 AutoSet Vantage the 95th percentile pressure shows up in the Efficacy Data menu whatever it was that night.

I wonder if that is a "bug" Resmed didn't notice for the S8 II internal software?

My Resmed VPAP Auto (bi-level) which first came out January 01 this year has the EasyBreathe technology like the S8 IIs but I've never seen it designated as an S8 II. And my VPAP auto does show the 95th percentile pressure for the night on the LCD screen.

You have me wondering now about the Resmed VPAP Auto 25 that came out July 01 this year. I've seen it designated as an S8 II and it has advanced to the Humidaire 4i integrated humidifier. I assume because it has a 5 cm higher pressure capability and they are allowing for a greater water capacity need.

I am thinking because I am using straight CPAP that they would assume they would not have to put the pressure results on the LCD screen because the pressure would be what was set up by the Tech. That is all I can figure out. Otherwise, I have no clue.

Ah, but if you use EPR your pressure would NOT be your set pressure!

Slinky:

I had the EPR turned off.

Set EPR at 1 for one night and see what comes up. I still wonder about it being a "bug" in the internal software that wasn't caught. And if other S8 IIs have the same problem. Curiosity killed the cat.

I will do that and let you guys know tomorrow. Thanks slinky!

Does it have to be "enabled" in the clinicians menu?

skjansen · Post by **skjansen** » Wed Aug 06, 2008 2:17 pm

Hobbs, I don't think so. I was able to turn it off the other day so I think I can turn it on.

Okay I enabled the EPR last night and when I reviewed my pressure this morning on my LCD it again said "no data". It does give data for AHI, AI, HI, and leakage. I just do not understand this. Also, there is "no data" for the week yet so I guess it will not give me that data until a week is up. I would have thought it would be a cumulative average week to date but I guess not.

Right now my leakage is out of control because my mask is leaking and my DME is taking their own sweet time shipping me a new mask. I think once I get that my numbers will come way down. Right now with a high leak rate my AHI is around 6. I appear to have no AI and all of the AHI is made up of HI. I guess that is positive.

Let me know what you guys think.

You are right for the weely data. It averages out for the week. Mine said no data until the week was up.

I am as curious as the rest of you on the Pressure readout. Mine has said no data since day one. This will be an interesting one to find out....

I am starting to think that because it is a CPAP machine it assumes you know that your pressure is what the tech set it at. The only other thing it could be is just some kind of bug in the internal software that Resmed is not aware of or if they are they just do not think it is an issue.

Anyone else have any ideas or any thoughts on how we can get to the bottom of this mysterY

Slinky,

Your VPAP Auto IS in the S8 Series II family, according to the text beneath the picture on the first page of the following pdf:

http://www.resmed.com/en-us/assets/docu ... sa-eng.pdf

SKJANSEN,

BTW, that page has a nice chart on epr.

And I think your assumption to be logical--there would be no need to tell you your pressure since your machine is running as a cpap. It would naturally be the pressure it is set at. I would assume that the 95 cnt treatment pressure would only need to be reported in an auto machine running in auto mode.

sk, my husband's S8 Elite II also showed Pressure 0 in the Efficacy data. He called ResMed & they said to send the machine back.
