ChatPPG interpretation

A 510(k) decision of "substantially equivalent" means FDA found the device as safe and effective as a legally marketed predicate. FDA's word for this is cleared, not approved. The clearance covers the device and indications in this submission; it does not extend to other features or versions of the same product that were not part of it. See FDA cleared vs approved.

Product code DQA is "Oximeter", class 2, 21 CFR 870.2700.
