Description
I am only considering files with PPG data in .dat file (e.g. p00/p000333/3092245_0040.hea), how can I match the PPG with the numeric SpO2 in e.g. 3092245n.dat?
The PPG and SPO2 have different lengths, even when accounting for sampling rate differences.
Is there any time reference I can take into account to know the file 3092245_0040 PPG time collection to match the SpO2 data in the numeric file 3092245n.dat?
Thank you very much.

Research direction
Start by examining 3092245_0040.hea and the linked 3092245n.dat file, along with the MIMIC-III Matched waveform and numeric-file metadata. Determine whether the files expose a time reference for matching PPG and SpO2, then document the confirmed matching procedure and limitations.
