Spo2 data format

[Squid3083]

This subject may already exist but I don't see it.

I would like to vave the format of a spo2 file.

I am making my own data logger of bmp and o2.

I would like to know of the simplest file format  to be able to link my future data with oscar.

Thanks

I thought i had read *somewhere* that the .spo2 format was just an EDF file with a different extension, but I can't find that now.

I'm very curious to know if that's true, because I am also looking into trying to write a small utility to convert from the CSV data that my pulse oximeter exports into something that Oscar can import.

If anyone has a few anonymized .spo2 data files they'd be willing to share, it would be pretty helpful.

To the best of my knowledge, the .spo2 file format is not the same as an .edff file. Certainly yhe code in OSCAR that reads the spo2 file is not the same as the edf parser code. The ResMed spO2 information is in an edf file which is read as the cpap data is read.

To return to the OP's question, the simplest data format is that used by the Choice Medical MW300 oximeter. It has a very simple header followed by the SpO2 and pulse data interleaved, one pair per second. Unfortunately, it is not documented anywhere in a text file, but it is fairly easily gleaned from the c++ file.

The "Choice Medical MW300 oximeter" is indeed simple, thanks for that tip!

Looking at the Oscar code for that loader, I was able to code a small utility to convert the CSV data from my Emay pulse oximeter into something that Oscar can import. 

It took just a few hours, so I'm sure the OP could do something similar with a small investment in time.

Muggzy,

I sent you a PM regarding this.  Any chance you could help me out with the MW300 file structure?  Possibly a sample file you created with your utility?  I'm trying to do the same thing for the Galaxy Watch.

Thanks in advance,

Gralli

Hi 
Muggzie, you wrote recently: "The "Choice Medical MW300 oximeter" is indeed simple, thanks for that tip!

Would you be able to share that utility or the steps used to convert the EMAY pulse oximeter.CSV files into something OSCAR can import? (such as the Choice Medical MW300 files?)  
I don't mind doing it in Excel if necessary, if that is easy (I'm not a coder), but a utility sounds very good.

It would be great if the OSCAR group could support the EMAY CSV format, as their devices are quite useful and durable.

Thanks!

The conversion utility I was referring to at the time was a GUI application that I unfortunately discovered an embarrassing bug in and haven't had the time and energy to resolve it now that I'm working on something far more ambitious, but I also have a command-line application that works for the purpose which is open source on GitHub it works for Viatom and Emay CSV formats.

I'm not sure if I'm allowed to post a link to it here. Is that allowable?

You can list the link, so long as it does not go to a DME's website.

Excellent, thank you for letting me know.

The code repository can be found at https://github.com/StagPoint/Pulse-Oxime...-Converter

There is a (not very good) video showing one way to use it here: https://youtu.be/N5fGQUmQgio

@Muggzy: could you convert this sample and repost it ?
