Even my Masimo MightySat has sometimes difficulties with accurate measurements, insanely low pulse 33 bpm (I am not Usain Bolt), low SpO2 but I just delete those readings from Health App.
It’s hospital-grade pulse oximeter with five parallel signal processors. I doubt $20 pulse oximeter from some supermarket is very accurate.
The next thing I’m waiting from Apple is blood pressure monitoring. Samsung already has it, it seems to be a joke. You need to constantly calibrate it with traditional blood pressure monitor.
