A flat pressure line

(http://s1304.beta.photobucket.com/user/ ... sort=3&o=0)
Any suggestions till I get my oximeter to investigate further.
Thanks.

I still say you should sell this machine. You're not going to find the answers you're looking for with this machine.

Here is some of my data for comparison. Enjoy!

The reason you have a flat pressure line is that you have your machine set for CPAP rather that Auto. You have the unit set for 5.

LSAT, it was set at 5-15 cm APAP.

Clicked on link. Image number 1 is blank to me. The other images show minimum of 4.0 and maximum of 5.0 pressure.
It looks like the max is set to 5.0 and that's where it stays.
Have you checked the SH data with smart code data?
I assume that you think the maximum pressure is set higher than 5.0. I have to ask...have you confirmed it by looking on the machine's clinical setup?

Edit...I see you say 5 to 15 APAP. Have you seen it yourself? Sorry but have to ask.

Pugsy,

Some how, I could not rectify the screen shot. On every trial in photobucket, it is blank, today.

Yes, my pressure is 5-15 cm for the last 4 days. I maintain this range, mostly. Just now, also, I have checked this in the clinical set up menu.

Today's smartcode is FN3F-FDF-3F8X. My 95th and 90th percentiles are 5.0 cm. EPI is 1 and AHI is 2.

Cosmo has repeated his suggestion of selling this machine. You may please look at his screen shots. It is similar to mine except I do not snore on the machine.

And you have yourself gone into the clinical setup menu and confirmed that 15 cm Maximum?
How about changing it to 5 cm CPAP for one night...see what the AHI is? Then change it back to APAP mode 5 to 15...see what happens. Maybe it is stuck like the S9 machines get sometimes.

The Smart code stuff matches SleepyHead...so that eliminates a possible SH bug.

Your reports look just like someone's report who has the maximum set at 5 cm. While I suppose it isn't impossible that the machine never wants to go above 5 cm...to have it do that night after night is statistically improbable.

Did you get your machine through private purchase or a DME?

Yes, 5 cm minimum and 15 cm maximum.
Alright, I will keep at 5 cm cpap, tonight.
Those screen shots show the maximum at 15 cm, similar to mine.
In the past, when I had kept the minimum at 3 cm and 4 cm with 15 cm as maximum, the result had been the same straight line.
However, I have found that at higher minimum pressure with a narrow range like 7-10 cm, there has been a tendency of some deviation from the usual straight line. But, then, AHI also has increased.
It was a private purchase.

How are you sleeping and feeling in general?

Let's see if the AHI increases with straight CPAP at 5 cm. If you need more pressure...it should increase. If you previously were using 7 to 10 range and saw some pressure movement...it just doesn't make sense that you wouldn't see any movement now.

I would be wondering what was going on myself. We wonder if the pressure is not right...then how accurate is the other data?
So I see your concerns.

I will do as you have suggested, today.

I get a sraight pressure line many nights as well. As you can see, I use the same machine. I have my pressure set at 11-13 cm. I check the SmartCode every day as well. My pressure on Sleepyhead is almost always a straight line (11cm). It has gone to 11.5, 12 or 12.5 or even 13 on occassion. The SmartCode shows the same. My AHI is almost always 0.5 or 1, unless the pressure line is up and down. On those occassions it is higher, of course. The SmartCode does round off the AHI and Sleepyhead is a bit more precise. The AHI is, of course, up on nights when my pressure does move up and down. I always know, by the way I feel the next day, that my pressure was up and down during that night, indicating more events. I have used my oximeter and have excellent levels there.

I have used the Intellipap Autoadjust for about 2 years now. I used a PR System One Auto before I went to the Intellipap Auto and my results, with that machine, are consistent with the results I get on the Intellipap auto. I stayed with the Intellipap because, once I got the e and i rounding dialed in, the machine matched my breathing much much better than the System One. I always felt rushed to inhale on the System One.

To me, this means that I have my machine dialed in well and I am getting very effective therapy. I don't get as much data with the Intellipap but I don't, personally, need all that extra data that the Resmed and the System One gives. I get what I need in terms of data and my oximeter, and the way I feel, show I am getting excellent therapy.

Hawthorne,
It was a timely and a welcome post from some body regularly using Intellipap Auto. May I still request you to kindly post your screen shots typical to the points you have mentioned.
Thanks.

I know you have asked me to do that before and I apologize for not getting at it. I have not posted data for a long time and I had trouble the last time.

I know this won't help anyone else but, if you want to PM me your email address, I wll be glad to send you some email attachments.
That I can do! Maybe you can psot my data results!

I have PMed my e-mail ID and been waiting for your post. Please post me your data at your convenient time.

My pressure last night was 5.5 cm straight CPAP. I slept for 7.39 hours and had 3 hypopnea (= a decrease) and 2 NRI events (new thing) though SH recorded the AHI as 0.78 (seems an error for sure) .

How can I compare this with my previous results? I find no connection. Am happier from this AHI decrease, any way.

(Sorry, I could not include screen shot. I do not understand why it becomes empty in the photobucket)
