Could you please tell me what sensor is used to collect blood oxygen data in edf files? THANKS.
Thanks for checking out the site. Sensor types will vary between study (dataset). Most datasets with EDF files contain a "montage and sampling rate information" page that includes data on sensor types.
For instance, here's the page for MESA - https://www.sleepdata.org/datasets/mesa/pages/equipment
Thank you for your reply, I forgot to say, I am using the SHHS data set, it seems that there is no such item "montage and sampling rate information".
