PSG Data from Sleep Study - EDF Formats
PSG Data from Sleep Study - EDF Formats
I had a sleep study in December and asked the sleep lab to provide me with the underlying PSG data.

The data is stored in "standard" EDF files (just like ResMed PAP machine data and data from various other devices).

This means that the data can be viewed with any generic EDF file viewer such as Polyman (in my sig).

Alternatively we can view the data using  "Phillips Respironics Sleepware G3" software.
The Phillips software looks very much like OSCAR but has extra capabilities to annotate events and create reports etc.

I have not explored the capabilities of the software but I've attached a few screenshots to give a feel for it.
The images look cluttered because all possible data graphs are turned on and there isn't it enough screen space to make that useful.

There is a heck of a lot of data available but I wonder if anyone even looks at most of it when doing a "vanilla" sleep study.

I don't know if most sleep labs would be willing to supply this data.  Nothing to lose... I just asked and they said yes.

Do you have a download link for Phillips Respironics Sleepware G3?

I (just now) googled for "G3 Software 3.8.1" and found 3 links.

I didn't test the download but the first two hits look OK coming from ..

You could try EDFbrowser.  The source code is hosted on EDFbrowser gitlab.  I have used pyEDFLib (which uses EDFbrowser) to inspect EDF files.  pyEDFLib is a python wrapper to EDFbrowser.  pyEDFLib  can be found on pyEDFLib download from PyPi.  If you are so inclined, (or talented) you can nearly recreate all of OSCAR using pyEDFLib.  

There's a learning curve on using EDF files, but I have to say they are quite effective containers for medical information.  ResMed PAP machines also store data as an EDF.  It would be really interesting to review PSG data.
