Some studies have indicated that certain physical traits, including, but not limited to darker skin pigmentation, finger thickness, and peripheral perfusion may create variations in readings that make the oxygen level appear higher than it actually is. Users should establish a baseline value when healthy and at rest. It is recommended that users consult a licensed healthcare provider on how to interpret user readings based on physical traits or characteristics.
