Spo2 data format

[capman]

@pholynyk:

comments out of md300w1_loader.cpp (oscar):

Code:

MedView .dat file (ChoiceMMed MD300B, MD300KI, MD300I, MD300W1, MD300C318, MD2000A)
Format:
Bytes 0  (1  2)
      id    n
n*11  0  1  2  3  4  5  6  7  8  9  10
      0  0  id yr mm dd hh mm ss o2 pulse
report title etc.

does the 0,0,id,yr.. set continue with o2, pulse, o2, pulse..
are there 3 bytes (a fileheader) in front of the 0,0,id,yr set ?
does the number of records take 2 bytes ?
what do you mean with report title etc. ? is there a filefooter ?

Code:

// Number of records
int n = ((unsigned char)data.at(2) << 8) | (unsigned char)data.at(1);

what are you doing here in detail ?

Thanks for this info. I have an Emay SleepO2 Pro that doesn't seem to output the csv that the other Emay oximeters do.

Hi All,

I have a Contec CMS70A. I have the data in .spo2 format. I need your help to extract the information in the format mentioned in the following research:

"
The UBFC-RPPG database  was created using a custom C++ application for video acquisition with a simple low cost webcam (Logitech C920 HD Pro) at 30fps with a resolution of 640x480 in uncompressed 8-bit RGB format. A CMS50E transmissive pulse oximeter was used to obtain the ground truth PPG data comprising of the PPG waveform as well as the PPG heart rates. During the recording, the subject sits in front of the camera (about 1m away from the camera) with his/her face visible. All experiments are conducted indoors with a varying amount of sunlight and indoor illumination.

And the data they provided in ground truth is open access in the drive here in txt file : https://drive.google.com/drive/folders/1...fAVw3EdJqk

It would be really helpful if anyone can guide how to get this readings from Contec CMS70A.
