The Apple Watch Series 6 feels like it has perfected lots of the features I appreciated about its predecessor. It has a brighter all the time-on display, a more powerful processor, quicker charging and two new colorful choices to select from. But the function I was most excited to try out was its new sensor that measures oxygen saturation in the blood (aka real-time SPO2 tracking) with the tap of a display screen. As someone who panic-bought a pulse oximeter at the start of the coronavirus pandemic and still checks her levels at the first sign of a cough, the thought of having one strapped to my wrist always was enough to pique my interest. But not like the ECG function 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, SpO2 on the Apple Watch nonetheless appears to be in its early phases. Navigating all this new knowledge can be daunting for anyone who's not a medical professional.



I purchased an FDA-cleared pulse oximeter, the machine medical doctors use to measure SpO2 on your fingertip, as a precaution when coronavirus cases within the US started to climb. Having low blood oxygen levels does not guarantee you have COVID-19, but it's considered one of the main symptoms of the illness. I had read horror tales of people that waited too long to go to the hospital and had died of their sleep as a result of they didn't understand their levels had dipped overnight. It's best to at all times verify with a physician in case you are experiencing shortness of breath (another symptom of COVID-19), even if a pulse oximeter says you're in a wholesome vary, but I found comfort in knowing that I may at the least use it as a reference if I ever skilled shortness of breath. That's not one thing you are able to do with the Apple Watch -- Apple says it must be used for wellness functions solely and not as a medical machine, meaning you'll should take the outcomes with a grain of salt and should not use it to display for any kind of illness, which is what I had been hoping to get out of it.



But there may be other advantages of getting it strapped in your wrist at all times. Very like a pulse oximeter, the Series 6 makes use of pink and infrared gentle from its new sensor to determine the proportion of oxygen in the blood. But as an alternative of shining the light through your fingertip, it uses the sunshine that's mirrored back from the blood vessels in your wrist to find out your oxygen ranges based on the colour of your blood. Throughout the setup process you are requested whether or not you wish to activate SpO2 tracking, which I did, however you may at all times go back 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 provides you a number of tips about the right way to get the most effective consequence and you want to relaxation your arm on a table or flat floor while the Watch is taking a reading.



Then the 15-second countdown begins and you are executed -- easy and painless. I acquired a 95% on my first learn, which was lower than what I'm used to from my pulse oximeter. Anything above 90% is generally considered by clinicians to be inside a healthy vary, however most often, real-time SPO2 tracking increased is healthier. I examined it just a few more times and obtained slightly completely different results within a couple of share points depending on whether I used to be completely nonetheless and silent in the course of the take a look at, where I had the watch positioned on my wrist and how tight the strap was. There are many components that can affect a studying, comparable to pores and skin temperature or the place of the sensors on the physique. Side-by-aspect with my pulse oximeter, the Apple Watch was typically off by about one or two factors, however generally spot on. What was more attention-grabbing to me was the SpO2 information that collected over time within the Health app .
