Can respiratory effort be inferred from OSCAR data?
With RERA being defined as either increasing respiratory effort or flattening of inspiration, and the latter being observable via flow limitation, can the former be observed from OSCAR data? If so, how? I believe with a PSG it is done by sensory belts around the chest and abdomen, something which is obviously not a part of CPAP.

RE: Can respiratory effort be inferred from OSCAR data?
Respiratory effort is normally evident in the flow rate graph. Flow resistance is indicated by flow limitation, or a flattening of the flow rate at peak inspiration, and in the time of inspiration. There also tends to be more expiratory rebound when excessive inspiratory effort is involved. I guess if you've seen it, you might recognize it. RIP belts are useful, but I think the PSG flow rate graphs are under-utilized.
