According to foreign media imore, the release of Apple watch series 6 is the first time to install an oximeter on a wearable device, which can detect the wearer's blood oxygen level. Apple took pains to make sure people knew the sensor was not medical grade, but things didn't go as the company wanted."Washington Post" reporter Geoffrey A. Fowler pointed out that Apple watch's blood oximeter is basically useless, because it gives contradictory readings.
"Sometimes, the latest Apple watch series 6 shows that my lungs and heart are very healthy, pumping 100% oxygen into my blood.
But sometimes it reports that my blood oxygen is too low, and I may have emphysema. (actually I don't.)
In this regard, imore's reporters also gave their own experience:
"For a few days, I've compared the results of my second apple watch with my FDA approved finger oximeter.
Apple's readings are usually 2 to 3 percent different - although they sometimes match perfectly, they sometimes fall by 7 percent. "
But this year, apple began selling a new elastic strap called solo loop, which comes in a variety of sizes. This product does eliminate some, but not all, error messages about unsuccessful measurements.
In fact, imore's reporter said they were surprised that people were comparing the blood oxygen readings of the apple watch with those of a blood oxygen analyzer approved by the FDA for this purpose. In response, the reporter specially posted Apple's official description of the apple watch oximeter: "blood oxygen app measurement is not used for medical purposes, including self diagnosis or consulting doctors. It is only used for general fitness and health purposes." So don't expect this device to help you in a medical emergency. Apple doesn't claim that its watch can do that.
