Hey - thanks for checking out the site.

A number of datasets have Pleth channels. Please look for the montage and sampling rate information pages to see what signals are available in each dataset. For instance, MESA - https://sleepdata.org/datasets/mesa/pages/equipment/montage-and-sampling-rate-information.md

Tools to extract/output might include:
