I wonder if the pulse oxes in China are calibrated for Chinese skin or White skin? Many people are buying pulse oxes straight off of Alibaba and they might be getting readings that are too low if the calibration is off.
- dogma1138 6y agoI’ll be surprised if they are calibrated at all.
- jschwartzi 6y agoLots of thermometers on Amazon aren’t even FDA cleared so I wouldn’t be surprised if the pulse oximeters aren’t FDA cleared either.
- oneplane 6y agoDepends on what you are measuring as well; if you want to know if there is a significant change you can do that. If you want absolute numbers you are probably doing it wrong anyway. (there is no single true template for numbers universally describing what a certain human should be like)
- CWuestefeld 6y agoChina is home to a tremendous amount of racial diversity, from the majority Han to Tibetans to the oppressed Uighur. Our western idea that "Asian" is a race is rather flawed. I don't think you can come up with any "typical" Chinese skin color. FWIW, my wife (Han, who grew up in Shanghai) generally has whiter skin than do I (a generic American of mostly northern European descent).
