With the pandemic, oximeters became popular, but their trend continues to rise, since no one had ever bothered to measure blood oxygen levels until now. It is a function available in a multitude of smart bracelets of all prices, brands, sizes and colors.
Controlling the oxygen in the blood is much more important than many of us can come to believe. But before we go crazy with the subject of oxygen saturation, it is convenient to know how it is measured.
There are different methods, one of them is the ABG test, that is, an arterial blood gas. Through this test, they take a blood sample from an artery (usually from the wrist) and analyze it. This method is very professional, exact and very rare, since it is only used in certain cases and it is not useful to measure it daily in our house.
Another method is to use an oximeter. The oximeters conventional ones that are placed on the finger of the hand, also on the foot or in the ear, and what they do is a direct oxygen measurement test using light absorption and taking advantage of the person's pulse.
Now it is convenient to know which oxygen levels are good and which are bad. A normal level oscillates between 95 and 100%. Below 60 it may require medical intervention, although that depends on the decision of each patient and the doctor.
Apart from the oximeter, we can also use smart bracelets and watches, since most of them have an SPO2 sensor. This sensor measures the percentage of oxygen in the blood and now we are going to tell you which are the best bracelets on the market to measure oxygen saturation levels.
Why should you have a bracelet?
It may seem like a useless accessory that will end up at the bottom of a drawer after 2 weeks, but no. Once we get used to living with a smart bracelet or smart watch and take advantage of all its advantages, our lives change for the better.
The bracelets have a multitude of functions and features, they do not reach the quality levels of smartwatches, but for the general public it is more than enough. Most of the smart bracelets on the market do not exceed 60 euros and among its benefits we find the possibility of receiving notifications, seeing the time, record steps, heart rate, blood oxygen, sleep quality, some can even answer calls, are waterproof, show us information at a glance, have a battery life of between 7 and 30 days, etc.
In short, it is time for us to change the century and start enjoying the benefits of smart bracelets and put aside the classic watch. Also, if we do not want the strap of our bracelet to always be black, we can buy interchangeable straps. They sell them on Amazon, eBay and in a multitude of e-commerce, apart from in the original store.
This is how you choose the best bracelet to measure oxygen
Before buying a bracelet at random, you must find out very well, its technical specifications, such as the battery, the type of charger, its certificate of resistance to water (there are those that are resistant to humidity and mild splashes up to depths of several meters). ), for what sports do we need them, the sensors it has, if it is touch, if its screen is shock resistant, etc.
As we see we have to be very clear about what we need and then start looking. Now we have two options, either search on our own on Amazon and trusted stores, or start asking people around us who understand bracelets and which one they recommend us to buy.
If it is the first time that we use a smart bracelet and we do not know very well how it goes, we recommend playing it safe, for example, a Xiaomi Mi Band, a Huawei Band or a Galaxy Fit. If we already have experience, then we can take stock of which functions we use more and which less. Maybe it's the perfect time to make the move to smart watches.
