Contec Oximeters Roadblock

I have attempted to use a CONTEC CMS 50D+ pulse oximeter. Sleepyhead will not let me import the data for some reason. It says to approve upload, or some such verbiage. I have pored through the manual and the menus on the device itself. Nowhere can I find any place such a permission is granted. Something must be wrong, as the SpO2 Assistant (software that came on disk with the device) will not allow a connection either. I am baffled. Maybe I got something wrong in attempting the recording of the overnigh data. Anybody hip to these gadgets?

I hope you are tracking the data from your CPAP machine using Sleepyhead. Except for people who have lung dysfunction, pulse-oximetry is not necessary. If your CPAP controls your apnea, you will not have oxygen desats.

Yes, I am tracking data from the CPAP machine, and of course that is my primary focus. During the in-home, the report (verbal, I have not seen it yet) stated that my O2 fell down in the low 70s. That prompted me to have a look myself, as that sounded pretty low (that is about where my father's was when he was dying form heart disease at age 88). I have coaxed some data from the device since posting. It showed a momentary dip to 89% (using CPAP), but the median score fell between 95 - 98. On that basis, I have to agree with your comment. That "low 70s" talk gave me pause though. I thought it imprudent to wait for official word of some sort. Cool gadgetry as a bonus. Thanks for your thoughts!

Whenever I see problems with one of these, I wonder if the user is using the cord supplied with the oximeter. They look like a regular mini usb, but they're not - you must use the one supplied.

I use only the cable supplied with the unit. Good point though.

That's why you look at the length of events in Sleepheady, BirdBrainTard.

Did you ever figure out how to use Sleepyhead? Is your librarian helping you?

xxyzx wrote:so you think you can eyeball from the length in the sleepyhead graph

It's not just a thought. I know any BirdBrainTard can figure out the length of an event in Sleepyhead if they just zoom in on the graph. But, it is much easier to open the events tab and look at the numerical value for the length of each event.

Well, you have demonstrated again that your ability to use Sleepyhead is little to nil.

Better beg your librarian to help you.

I have found that the Contec 50D+ a little hard to work with. It will not download the data unless it has been turned on. If you turn it on and you don't have your finger in it, it promptly turns itself off. I found that turning it on while connected to the computer and my finger in it helped me get the data off. SPO2 Assistant is also easier to use than Sleepyhead.

and that is so not true

we went over that in previous discussions

you can have AHI that is very low
and still have desats

one apnea for a long time is more than enough to do it
ditto hypops

you cannot know that your spO2 is okay just because the apnea is 'treated'

AHi is just a mostly meaningless statistic for bureaucrats to decide if you need treatment or if it is 'working'
you need to look at all the data including spO2 and RDI and others to know how you are doing

This is the kind of stupid, inaccurate misinformation which has led many to add to their signature:

BEWARE, information from XXYZX is usually wrong and may be dangerous. Ignore him!!

amateur software
bad documentation

if you play adventure with it you may stumble on a set of actions that work
i did once
and got the data to load okay
never could recreate the same sequence again

Idiot boy admits his total incompetence and then goes and gives advice. Yes, the cord for the CMS50D+ is proprietary. Also, after recording DO NOT turn the unit off before downloading into Sleepyhead. I found it better to use SpO2 Assistant program to download a file, and then load that into Sleepyhead.

Anything you ever got right was by "stumbling on it".

xxyzx wrote:but you cant tell what that length did

You don't need to "tell what that length did". (Good grief, I'm starting to talktard like him.) You just need to know that if your events are long and/or frequent, your CPAP process needs to be tweaked to ameliorate the events.

xxyzx wrote:that is something you cant grok

I'll leave the groking to your ilk.

xxyzx wrote:i dont have to demonstrate anything to you

True, you've already shown all your cards, and you've got a 2-7 offsuit hand.

xxyzzzshit wrote:fixing AHI is nice
but fixing spO2 is critical

The same stupid stuff you have been posting since you first saw a consumer oximeter on Amazon.

In the context of a patient without lung dysfunction, use CPAP to fix the events, and the SPO2 normalizes.

xxyzx wrote:and lowering it under 5 does not guarantee your spo2 is at a safe level

Of course it doesn't, dimwit. You have to look at Sleepyhead to check the length of the events and whether or not they are clustered. But, you don't have the sense to use Sleepyhead. See your librarian. (If he hasn't already kicked you out on your ass.)

xxyzx wrote:AHI is just a crude statistic for medicrap bureaucrats to decide if they will pay for treatment

Constantly repeating your mantra is very unattractive.

xxyzx wrote:no matter how much you prove that by claiming you can eyeball some graphs to really know what is happenign

Much better than you can eyeball your oximetry report to know how to tweak your CPAP settings. In fact, your oximetry report will tell you nothing about how to tweak your CPAP settings. (If you could even read your oximetry report.) Get in touch with your librariantard.
