With the pandemic, oximeters became popular, but their trend continues to rise, as no one had ever cared about measuring oxygen levels in the blood until now. It is a feature available in a multitude of smart bracelets of all prices, brands, sizes and colors.
Controlling oxygen in the blood is much more important than many of us believe. But before we get crazy on the subject of oxygen saturation, it helps 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, a blood sample is taken from an artery (usually from the wrist) and analyzed. This method is very professional, accurate and very rare, since it is only used in certain cases and is not used to measure it daily in our home.
Another method is to use an oximeter. Conventional oximeters that are placed on the finger, also on the foot or on the ear, and what they perform is a direct oxygen measurement test using the absorption of light 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 is between 95 and 100%. Below 60 may require medical intervention, although that already depends on the decision of each patient and the doctor.
Apart from the oximeter, we can also use bracelets and smart watches, since most have an SPO2 sensor. This sensor measures the percentage of oxygen in the blood and now we are going to say which are the best wristbands 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 in 2 weeks, but no. Once we get used to living with a smart bracelet or a smart watch and take advantage of all its advantages, our life changes 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 smart bracelets on the market do not exceed 60 euros and among its benefits we find the possibility of receiving notifications, seeing the time, recording steps, heart rate, blood oxygen, sleep quality , some can even answer calls, they are resistant to the water, they show us information at a single glance, they have a battery life of between 7 and 30 days, etc.
In short, it is time for us to change the century and begin to enjoy 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.
How to choose the best bracelet to measure oxygen
Before buying a random bracelet, you have to inform yourself very well, of its technical specifications, such as the battery, the type of charger, its water resistance certificate (there are them from moisture resistant and mild splashes to depths of several meters ), what sports do we need them for, the sensors it has, if it is tactile, if its screen is shock resistant, etc.
As we can see, we have to be very clear about what we need and then start looking . Now we have two options, or search on our own in Amazon and trusted stores, or start asking people in our environment 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 the most and which we use the least. Maybe this is the perfect time to make the move to smartwatches.
These are the best smart bracelets
If we have convinced ourselves and want an activity bracelet with which to measure oxygen levels in the blood, then we are going to leave the best options to buy on Amazon.
Xiaomi Mi Band 6
At Amazon we have it available for 46 euros. The good thing about this smart bracelet is that it was a pioneer brand in smart bracelets where we received notifications, counted steps, recorded sports, marked the time, etc. Now in its sixth generation it includes a 1.56-inch full color screen, different monitoring of activity, sleep and, of course, blood oxygen.
This bracelet has an autonomy of 14 days and its charger is with magnetic pins. The Xiaomi Mi band 6 has water resistance of up to 50 meters, so we can use it for swimming without problems. It has 30 sports modes, we just have to select the one we are going to practice, press start and start recording the training, at the end, we receive the statistics on our mobile through the official app.
Huawei Band 6
The sixth generation of Huawei’s basic bracelet comes with a rectangular design, large 1.47-inch color AMOLED screen, 15-day battery, constant monitoring of heart rate, steps, sleep and with a SPO2 sensor to know our oxygen levels. in blood.
The company ensures that heart rate control is very accurate regardless of gender, age or even skin color thanks to Huawei TruScreen 4.0 technology . Something similar happens with sleep monitoring thanks to TruSleep 4.0, being able to identify the sleep phases and then show the results.
With this bracelet we can choose from a multitude of sports, press play and then receive the statistics on our mobile through the Huawei Health app.
Honor Band 6
It seems that we are talking about the same bracelets, but no, it is that the manufacturers have used the word Band in all of them. In this case, the smart bracelet that Honor offers us has a 1.47-inch AMOLED color screen, 2-week battery with magnetic fast charge, 10 training modes, smart assistant, interchangeable straps, reception of notifications and calls, etc.
Regarding the sensors, this smart bracelet offers us monitoring of sleep, steps, 24/7 heart rate, steps, stress control and even blood oxygen, otherwise it would not be on the list of the best bracelets to know our saturation of oxygen.
Regarding the guide, this bracelet is resistant even suitable for swimming. So much so that it records the exercises we do in the water and one has a resistance of 5 ATM . Even in water, there is oxygen and heart rate measurement, as well as distance, calories, and more.
Samsung Galaxy Fit 2
Samsung bracelets are usually best-sellers and it does not surprise us, since this time we have a multitude of sensors apart from the one that interests us today, which is the SPO2 to measure the level of oxygen in the blood 24/7 from our wrist. We have a heart rate monitor that works 24 hours, accelerometer, gyroscope, sleep monitor to record rest, alarm, receiving notifications, battery for 15 days, water resistance up to 50 meters, stress detection, etc.
All these statistics will reach the official Samsung Health app that we must have on our mobile and with which we have to link the watch with the mobile. And without forgetting that the bracelet has a 1.1-inch color 3D AMOLED screen that is easy to read even under water. On this screen we can receive notifications, health notices, calls, choose exercises, see the time, time, etc.
Amazfit Band 5
It is one of the best-selling bracelets and that is due to its price and how complete it is, since for less than 28 euros we have a 1.1-inch color touch screen, integrated Alexa, NFC, Bluetooth, battery for 2 weeks, interchangeable straps, heart rate tracker, SPO2 sensor , step counter, etc.
A complete bracelet that comes to compete with an entire sector dedicated to sports bracelets, especially those that measure oxygen saturation in the blood. The big difference is that this bracelet has a voice assistant, something very unusual in sports bracelets, but more normal in smart watches and other devices.
Actually, it is not a bracelet, it is a smart watch, but being medium in size and costing less than 50 euros, we wanted to put it in this compilation. On this occasion, the battery lasts 10 days and has different sensors, receives notifications, music control, activity reminders, water resistance up to 5 ATM, etc.
Among the sensors, we want to highlight the temperature sensor capable of measuring body temperature, the SPO2 sensor to measure blood oxygen saturation, the step counter, the 24/7 heart rate recording, recording of up to 14 sports modalities , sleep control, respiratory rate control, among others.
