Does Fitbit 4 monitor oxygen levels? null

The short answer is no, at least not with the same method and precision of a pulse oximeter. The device estimates changes in blood oxygen saturation during sleep, but the additional information provided in the FitBit app doesn't specify exactly how this estimate is generated, just that the estimate is made only during sleep because too much movement interferes with the light emitted from and reflected back to the device.
