Understanding my Philips System One

Post by Inspectorgene » Thu Feb 26, 2015 1:35 pm

Started on the System One last October. BTW, as far as I know I am out of compliance checking at this time...
Had a screwy DME and am in process of changing to a different one now. The respiratory therapist was of little to no help in getting me started.

So....Started out at straight CPAP press of 12 based on scrip by doctor

Began playing around with the machine on my own a few weeks ago, and discovered CPAP-Check and Auto Trial.

I went into the setup and put the machine just in CPAP-Check mode.

My pressure stayed at 12 for a while, and then I noticed it was 11 and then this AM it was at 10.

BUT last night my AHI was up to 3.6 and it had been 2 or under and sometimes under 1.

I did a lot of reading today and I now understand that my machine can be put into Auto Trial for up to 30 days, 3 being minimum
and then transition into CPAP-Check mode which will then check and adjust pressures every 30 hours.

1. Did I screw up by manually entering CPAP-Check mode?
2. Do you think the lower pressure increased my AHI?
3. Should I go back to Auto Trial and let the machine just do what "it need to do"?
4. Just be satisfied with the 12 that the doc recommended and stay on straight C-pap?

Thanks in advance for your time and consideration.

Nothing wrong with using the auto titration of the Pro model to see if different pressure improves therapy or comfort. It sounds like CPAP at 12 cm is pretty darn close to optimum for you, but the C-trial is there to evaluate whether changes might be beneficial. Give it try for at least 3 days and if you decide the fixed pressure at 12 was better, you can always go back. Anytime you make changes, the events seem to increase, so give it enough time to stabilize, then make a decision.

You're doing pretty good at this point, so congrats on that.

1...No
2...Yes it's possible but it could also be simply a variation in nights that people can have even without changing anything
3...That's a choice you have to make but what are you trying to figure out? Were you trying to fix a problem or just play with the settings?
4...What caused you to change from cpap mode in the first place? Unhappy with results? Eventually you will have to use cpap mode anyway with this machine as the apap mode function is limited in the number of days you can use it.

I personally wouldn't rely on the CPAP Check mode and would prefer to evaluate my pressure needs based on what I see on the software reports. A person can have a great AHI and still have suboptimal therapy if a lot of snores and FLs and RERAs are present and we are never told just what the cpap check mode feature looks at in determining pressure needs but I assume it is AHI.

Thanks for your reply.

I guess I decided to experiment because I had such a crappy experience at the sleep lab. I did sleep over a couple hours at a time on either visit, I never personally even met or talked to the doctor, and my DME experience was pretty much a disaster.

I just don't necessarily trust anyone involved in the process, so I decided to experiment on my own.

I have installed SleepyHead, but those graphs look like hen scratching to me.

Post a screen shot of a couple of daily detailed reports along with what questions you have about what you are seeing and we will try to clarify.
I have a tutorial that sort of covers the basics....link in my signature line. Check it out as it should help clarify some things.
For instructions on how to post images of your reports as well as examples of what we like to see (we don't need all 12 graphs)
viewtopic/t103468/Need-help-with-screen-shots.html

I think there is a way to get you more than 30 days of apap trial mode by doing a therapy reset little trick...or at least we used to do the reset 5 times.

So there should be enough apap days available to figure out an optimal pressure...and heck...the 12 cm cpap might just be it.

Welcome Gene :

Here is a link to information about sleepyhead software, half way down the page is a link to informatin on how to set up the charts for posting here

https://sleep.tnet.com/resources/sleepyhead
If you're not part of the solution you're just scumming up the bottom of the beaker!

Get the Clinicians manual here : http://apneaboard.com/adjust-cpap-press ... tup-manual

This is from last night.

The machine had changed pressure back to 12, but I did some fooling around with it, so I may have reset something...

Thanks in advance.

Report looks pretty good to me except for some large leak.
Did you have a specific question about something?
That red line you see is for ResMed machines...not your machine. Your large leak number to avoid is going to be up around 75 to 90 L/min and varies with pressure and mask used.

If you turn off the pie chart we could see the machine settings and the AHI totals better.

Thanks for your reply. I will try another time. I think I have it figured out... maybe

Not looking for anything specific, just help in interpreting the graphs.

The LED readout on the CPAP machine itself shows NO leaks.

I have the Airfit P10, and I don't notice any leaks on my own.

I can't seem to squeeze the whole thing onto the page, but the graph is a clickable link.

SleepyHead is reporting 10% of the time in large leak territory (statistics section) but it isn't flagging large leaks in the events graph... so I am wondering where it is getting that number from.
If the machine is saying 0% of the time in large leak on the LCD screen then that's what it is.
Maybe a little SH bug.

he's got an old version of SH (no welcome tab next to data and overview), so it doesn't flag the over redline bits on the chart.
