Adjusting Leak Rate to increase CO2

Thanks. Saw all the notes concerning that. Sleepyhead installs fine. USB device not recognized. Using cable that came with it.

Go to device manager.

Run ÓPen-GL version
The program can't start because MSVCR120.dll is missing from your computer. Try reinstalling the program to fix this problem.
Run Broken GL version
Same problem

Been through this several times before. Used different Windows compatibility modes.

Did you get Sleepyhead running or was stopped by the missing dll? If you still need the missing dll you can download it from here.http://www.microsoft.com/en-gb/download ... x?id=40784
I had to do this with my computer.

I think you made the same mistake I did when I first read his post... he's tuning blind, ie no data to go by, not turning blind. (which is good!)

OK, so it's my vision.

I ran the Sleepmapper from Respironics. Now when I ran Sleepyhead it read the stick.
Still won't recognize the oximeter.

then you don't actually have the right drivers installed for the oximeter.

I've used a cms50i on the spo2 asst and sleepyhead on win7 64bit.

You can always dump your oximeter data to a file and have sleepyhead read the file. I have found that combination of my computer, oximeter, and sleepyhead is finicky, sometimes it works, sometimes it does not. The file method always works.

Can't dump it to a file if it isn't recognized on the USB.

Are you sure you are using the right cable?

Stooopid. I did not know I had another cable with that plug on it. I should clean the clutter off my desk. I was going to say of course it is the right cable, I only have one like it.

OkyDoky may be more correct than we thought. I am going blind

It's working now. Now I have to learn how to read everything. Thanks all.

I'm probably confused from CO2 poisoning

OK... here is a brief CO2 re-breathing test. This was done without equipment.

Laying on my side, I cupped my hand over my nose to provide a capture space. If my breathing became labored I just lifted a finger slightly to change the mix. As I dozed off again the finger would drop.

It's not a perfect test because I wasn't fully alseep, just very drowsy.

You can see a steady breathing during the time of the test, where free breathing on the left and right side show the effects of periodic breathing and the associated dropping of the SpO2.

Interesting, you spend a lot of time at relatively low SpO2

I also notice your report is still dated 2014...so this is last year, or you have entered the wrong date?

I'm finding OkyDoky is a sharp one.

I ran into the same cable problem that you did, except with my D+. I used it, and it was fine, then I happened to grab a regular usb mini cable, and it didn't work... it was only later, when I was working with jedimark on sleepyhead, that I happened to grab the right cable, and I was watching the logfile on linux, getting the usb codes, and to my GREAT surprise, I got a "device detected" message when I plugged in the CABLE! without the oximeter connected to it!

a little more poking around, and I found that the cable that comes with the d+ e and older f oximeters is NOT a usb cable. it just looks like one. I think that was a poor design choice on their part, but probably saved them a couple pennies on each unit.

the cable has a usb<>serial coverter chip in the large plug end, so it's really a SERIAL cable that plugs into USB... I suggest marking it as special, because, of course, it won't work with anything else that needs a usb cable

It was taken just last night. I haven't configured anything. That reading is without the CPAP. So not spending a lot of time below 88 is good for me. I drop the most when my heart rate slows to 45, then SpO2 can drop quickly to low 70's.

The segments are labeled in the text. The CO2 remix was done just using my palm. Sort of a proof of concept test using real data rather than just my perceptions.

In my case, the nazal pillows created too much CO2, so I am not blocking it, but have punched holes in it. As I increase the leak, more of my breath can escape and reduce the amount of rebreathing at the same pressure. When I want to increase CO2, I adjust the pressure down.

Hi.
i agree that making extra holes on mask can reduce co2. Do you think that making extra holes and increasing pressure can solve co2 rebreathing problem without high AHI?
and i've sent you private message. Please check the message...
