The Apple Watch Series 6 feels prefer it has perfected lots of the options I preferred about its predecessor. It has a brighter all the time-on show, a more powerful processor, sooner charging and two new colorful choices to choose from. But the function I was most excited to check out was its new sensor that measures oxygen saturation within the blood (aka BloodVitals SPO2) with the tap of a screen. As somebody who panic-bought a pulse oximeter at first of the coronavirus pandemic and still checks her levels at the primary signal of a cough, the thought of having one strapped to my wrist at all times was sufficient to pique my curiosity. But in contrast to the ECG characteristic on the Apple Watch, which has been tried, examined and cleared by the US Food and Drug Administration, along with the irregular heart rhythm notifications, BloodVitals SPO2 on the Apple Watch nonetheless seems to be in its early phases. Navigating all this new knowledge may be daunting for anybody who's not a medical skilled.
I purchased an FDA-cleared pulse oximeter, the device medical doctors use to measure BloodVitals SPO2 in your fingertip, as a precaution when coronavirus circumstances in the US started to climb. Having low blood oxygen levels would not guarantee you've got COVID-19, however it's one in all the main symptoms of the disease. I had read horror tales of people that waited too lengthy to go to the hospital and had died of their sleep because they did not understand their ranges had dipped in a single day. It's best to at all times verify with a physician if you're experiencing shortness of breath (one other symptom of COVID-19), even if a pulse oximeter says you're in a wholesome vary, however I found comfort in realizing that I might at least use it as a reference if I ever skilled shortness of breath. That's not something you can do with the Apple Watch -- Apple says it needs to be used for wellness functions only and never as a medical system, that means you will should take the outcomes with a grain of salt and shouldn't use it to display screen for any type of disease,  BloodVitals SPO2 which is what I had been hoping to get out of it.
But there could also be different advantages of getting it strapped in your wrist always. Much like a pulse oximeter, the Series 6 makes use of red and infrared light from its new sensor to determine the share of oxygen within the blood. But as a substitute of shining the light by means of your fingertip, it uses the sunshine that's reflected back from the blood vessels in your wrist to find out your oxygen levels primarily based on the color of your blood. In the course of the setup process you are asked whether or not you want to activate SpO2 tracking, which I did, however you may all the time return and disable it in the settings after the fact. The very first thing I did after strapping on the Watch was open the Blood Oxygen app. It gives you a number of recommendations on how to get the best result and you might want to relaxation your arm on a table or flat surface while the Watch is taking a studying.
Then the 15-second countdown begins and you are finished -- easy and painless. I obtained a 95% on my first learn, which was lower than what I'm used to from my pulse oximeter. Anything above 90% is mostly considered by clinicians to be within a healthy vary, however most often, greater is healthier. I tested it a number of more instances and got barely completely different outcomes inside just a few proportion factors depending on whether or not I used to be completely nonetheless and silent throughout the check, where I had the watch positioned on my wrist and how tight the strap was. There are a lot of components that may affect a studying, comparable to skin temperature or the position of the sensors on the body. Side-by-facet with my pulse oximeter, the Apple Watch was typically off by about one or two points, but typically spot on. What was extra fascinating to me was the BloodVitals SPO2 information that collected over time within the Health app .
