When I explore the EDF data in the CHAT dataset, I found the SAO2 value in the EDF is much higher than 100.

So what should I do to recalibration the SAO2 data? Thanks!

Thanks for raising the issue. The CHAT SaO2 values > 100 is discussed on these pages:

Note that only one (1) participant has values exceeding 100 during sleep time. Wake time was not always reviewed for signal artifact.

These data are provided "as-is". We leave it up to the user to decide how to handle (e.g. exclude portions of signal(s), recode values, etc.)

Good luck and thanks for checking out the site!
