how does an oximeter (Contec) hook up to Oscar/machine

[tyrinryan]

I’d like to buy an oximeter to hook up with a resmed AS10 and get the overnight O2 data displayed on Oscar. How do these oximeters plug in to the resmed AS10? Or how does the data get synched? And retrieved into Oscar? If the machines have to be synched, how do you get the timing right? What are the differences in the various models that Oscar supports: Contec 50D+; 50-E; 50E; 50F; 50H; 50I; Pulox 200/300/400/500? Where is the best place to buy one? Does Oscar support the (expensive) resmed dedicated oximeter that plugs into the side port of the AS10 model?

Sorry to trouble with all the questions. Is there some post somewhere that does a little Wiki on this?

None of the Contec CMS oximeters will work physically hooked up or plugged in to the ResMed cpap machine as in have the cpap machine itself record the data.
They will work with OSCAR/SleepyHead though. You just have to import the data separately which is easy to do.

Now there is a pulse oximeter model made by Nonin I think it is that will/can physically hook up to the AirSense cpap machine and it will set you back around $1,000 plus some sort of attaching thing cost to do it.

The Resmed oximeter is about 1000. Does Oscar support it?
If the Contec models do not plug into the resmed machine, AS10, how do you synch up the two devices to see if your O2 is dropping on a particular breath? Would not that require a very precise time setting?

[Pugsy]

OSCAR supports the ResMed machine data and in that way it supports the Nonin data because the data comes from the ResMed machine.

The Contec or CMS or other devices have various models that do different things and some actually have clocks that you set so you can sync times with your machine clock. Makes it easy.
The CMS50 D Plus...does NOT have a clock so people had start the pulse ox manually at the same time as they started their cpap machine.

I am not full up on all of the various features and /or differences with each model but I think any Contec model above the DPlus offers a clock for syncing.

If timing syncing was important to me...I would look at probably the 50 F model. I don't remember much about the 50 E model ...sorry.
There are others here who can explain the minute feature differences.
I used to have a 50 D Plus...I haven't researched any of the Pulox brand models.
The 50 D Plus was cheap and sufficient for my needs. I didn't care about syncing or anything like that. I wanted an overall evaluation of the night in general and I knew that I wouldn't be wanting to zoom in on anything and it was unlikely I would even use it regularly so I opted for cheap. I was correct...I used it twice and saw my O2 levels never ever dropped and my cpap therapy was effective and that was all I needed.

But if I wanted more detail and the timing and clock sync was important...in the Contec models I would look at the 50 F or maybe the 50 I if I wanted the extra details it offers.

It's been years since I really looked at pulse oximeters because I haven't had a need. So I can't really give you a blow by blow difference except to tell you that since a clock is important to you....don't look at the 50 D plus and anything less than the DPlus doesn't record all night.

Thanks pugsy for such a detailed and personal reply.
It seems extremely difficult to find these oximeters now in Clovid times.
Like you did, I would like to see if my O2 levels vary through the night. I saw someone's Oscar printout with a line for the O2 and it looked like a really neat thing to have. The d plus model did not seem expensive if you could find one and I thank you for your observation about the lack of a clock. I think a clock would be helpful if in fact there was any drop in O2 levels from time to time.
When you import the Contec data into Oscar, does it display as a line of graph(just like the flow rate) perhaps out of synch if you don't synch the times on the devices perfectly?
Further what about the Dreem2 product. Is it the same drill as far as importing the data?

Assuming a CMS pulse ox model with a clock to set....I do believe the times are clearly seen. Since I no long have a pulse ox in my possession I cannot test it but a lot of forum members do and I assume that they can chime in with examples so you can see if that would meet your needs.
I would assume that the clocks on the pulse ox and ResMed cpap machine could be synced up close enough.

As for the Dreem 2 product. I have no opinion on it whatsoever because I haven't had the need to investigate it at all.
I have no idea at all how any information gets gathered or reported with this product.

Following this.

According to https://www.concordhealthsupply.com/Wri ... /75006.htm, the CMS-50F is only compatible with Windows computers, which is a limitation for me. I'll continue looking.

Ideally, I would like a finger sensor something like this one...


Unclear how to put all the pieces together at the moment. Will ask about it during my appointments this week.

I may just get this, though, since Oscar supports it.

rsskga,
I have an imac. I have a CMS-50FW (blue tooth version). I put the oximeter on record. Then stop recording in the morning. Take the usb to mini usb cord (I think it is a mini) used for charging and data transfer that was supplied with the Contec device, plug it into the CMS-50F and the imac. On Oscar, after you imported your cpap data from the SD chip, then choose Oximetry, and then choose import directly from a recording device.
Voila - loads the Oximetery data. You even get to choose to use the timestamp of the Oximeter or match it to the start of the xPAP, or choose your own starting time .[attachment=0]Screen Shot 2020-06-01 at 6.51.12 PM.png[/attachment]

Awesome! It sounds like because Oscar is cross-platform it doesn't matter that the Contec software is Windows-only. Thanks!

[Norma45]

Yes. Oscar does the same thing as the contec software that runs on windows only - displaying what the watch recorded. Oscar can read (speak) contect watch

I am considering to use an oximeter with my Resmed CPAP on Oscar but I am not clear how and where to physically record the Oximeter data to import them into Oscar.
1. Is there a USB outlet and cable on the oximeters? On all the oximeters listed on Amazon I haven’t seen any USB outlet.
2. Where does the oximeter cable, if any, connect to?
3. Is there a separate SD card to record the oximeter data to?
4. How are these data transferred from the oximeter to the SD card?
I suppose it is not the same SD card that is plugged in the Resmed machine for the nightly sleep data.
5. Is it really necessary to transfer the oximeter readings to Oscar? Can’t I read them off directly from the oximeter ?
Thanks

Ittiandro,
You might check out this link to the Wellue oximeter ring. It's a high grade device that easily imports your SPO2 and Heartrate both of which are measured continuously, into Oscar. If you do have an interest, check Amazon also. they may have it cheaper and you'll get it sooner. I use it and it is excellent, no cords and you hardly know it's on your finger. The company site offers a 10 per cent discount also.

You also need to consider comfort when wearing these things.

During my PSG test, the lab put both type on me.

They put the clip-on type similar to that shown in the pix referenced by Norma45 and wrapped with medical tape. They wanted a unit with display so that that they could spot check SpO2 if necessary. The clip pressure after a while was painful and very, very, very annoying.

By contrast the sensor type referenced by rsskga felt barely there even though it was similarly wrapped in tape.
