How works sensor-level oxygen blood watches

The epidemic we suffer from disease is increasing our vocabulary with many medical ideas. This is happening when your car is broken. Professional mechanics come out everywhere, knowing what is wrong with you if you don’t even open the hood. The same happens with Covid, the degree without doctors has increased, diagnosing what is happening to you, and of course. With advice. One of the new ideas we have learned is “Blood Oxygen saturation”.

Clock manufacturers are rapidly implementing an oximeter function on their models. 2020, and due to Covid, it has been the year to launch many watches with this function. And this is today’s post. What does this mean, and since smart watches can give us a study of our saturation?

What is blood oxygen saturation?

Blood oxygen saturation levels are one of the important indicators through which it can be decided if the patient needs to obtain oxygen through the mask or if it depends on its level, artificial ventilation.

For example, at this time, the hospital decides whether the patient needs to be admitted to the hospital. Covid 19, a virus that affects the lungs, especially its tissue, which can cause severe pneumonia. Who recommends the management of oxygen to patients with less than 90 % saturated levels? A healthy person should have oxygen saturation levels between 95 and 100 %.

How to control oxygen in the blood

The best way to control your oxygen saturation, if you face breathing problems, and much more, is to go to a hospital to identify how you should move forward –

But if you want to maintain control, there are two ways. By watching an oximeter or bracelet or SP02 clock. They are non-invasive photoelectric devices that measure heart rate and blood oxygen levels.

Oximeter operation

An Oximeter is a non-invasive Medical Photo Electric device that measures heart rate and blood oxygen levels.

The operation is very similar in both devices, though they have different ways to measure, so the result is usually different.

The measurement is only achieved by illuminating two waves of light (one red ray and the other an infrared ray) that excludes LED sensors placed on the devices. Censers remove this light by moving the tissues through the blood.

When the blood becomes oxygen when passing through the lungs, hemoglobin is converted to oxyhemoglobin, so that it can transport oxygen. Two compounds, hemoglobin, and oxygen hemoglobin have different levels of absorption of different light waves that exclude sensors. When the blood is crossed, let’s pass more or more light.

And so far the two devices are the same, and now there are differences between one and the other.

The difference between the traditional Oximeter and the smartwatch

A traditional Oximeter is a clamp with light emitters and data on the other side of the clamp. When the light goes aside, it crosses the blood, the amount of light that reaches the recipient is the one that determines the percentage of oxygen in it.

In the case of the clock, the data recipient is in the same place, such as the emission of LED lights. Therefore, the light that does not cross the blood, re-bounce and returns to the clock, which determines the percentage of oxygen.

And this is the first way to take the measure, the first method of differences.

The other is the area of ​​measuring blood oxygen that we have. The traditional Oximeter is taken on the finger, even in the ear lobe. Highly sensitive fabric areas, under which LEDs pass more easily and read more real. The doll is not a drug -recommended area to measure this type.

Keeping up with the measurement

For example, not keeping tattoos or enamels, that the measuring zone is not cold and remaining fully irrelevant during the process, the recommendations of the medical experts, which are in progress, we must take it.

Although brands such as Apple or Garmin, are using resources to improve blood oxygen measurement on their devices, together with medical professionals, in case of health problems yet reliable do not have. They suggest that they do not use their watches for medical purposes.

Therefore, it is not logical to buy a watch with a Blood Blood Blood Oxygen measurement function to stop Covid, as they will only read us close, and you will know already before other symptoms.

And of course, it depends on the clock, the error can be minimal or unrealistic. So I advise you that, if this is one of the functions that you are interested in in the clock, you use it as a recreational style of medical factor to confirm your health status Using. For this, at least, I still bet on health centers.

There are some famous watches here with the function of reading oxygen saturation in the blood.

1. Amazing Band 5

This a proposal for people that are looking for something more cautious than a watch and do not want to spend a lot of money at the same time.

This watch can help you control oxygen saturation, heart rate, and stress in the blood. Analyze the dream, as well as count the steps every day without GPS.

All of this is put on a small device that has a 1.1 -inch screen (AMOLED), is water resistant to 5 ATM, and has a battery life of up to 15 days in general use. And if you leave the charger on a long journey, you don’t have to worry about running out of clock. With a battery-saving function, you can reach 25 days with it. Small watches reach this sovereignty.

2. Samsung Galaxy Watch 3 LTE

If you are looking for a good screen smart watch, this can be a good choice. There are very few tools in the market that can be similar to the quality of the Samsung product, which offers a Korean watch offer.

First of all, the watch works with virtual SIM cards, so we don’t need to take our phones with us. The watch becomes our phone freely. We can receive calls or send messages with the phone at home.

The Samsung Galaxy Watch also offers 3 LTE health control functions. From the measurement of oxygen saturation in the blood, I have talked to you today, through sleep analysis, GPS race training, and heart rate measurements. All with a classic watch box and great quality AMOLED screens used on this type of device. Everything, of course, is resistant to water up to 5 ATMs, so regardless of whether we are going to run, ride or go into the pond, we do not need to remove the Galaxy Watch 3 LTE from the wrist.

As a novelty, it includes a rotating bezel that facilitates menu navigation, even gloves.

3. German Fenix 6 x Pro

I recently talked about this post in this post. And you can see that this is personally one of my favorites. Garman Phoenix is ​​the king of 6 high-performance sports watches. It contains everything that can expect from a fan of ultra-marathon, triathlete, or mountain campaigns. and of course. What is happening in today’s article, is the oxygen control function in the blood, which not only allows manual measurement but also 24/7 measurements or at night, on the clock, and with all the measurements recorded in it. Application of Garman Connect.

Fenix  6 x Pro also keeps the height we find (added altimeter)

Fenix also offers integrated topographic maps with 6X pro -navigation, a wide range of performance parameters, detailed analysis of race parameters, adaptive carrier training… I am not a professional athlete, but if you have There may be very little need.

In addition to the part of the sports, Phoenix 6X Pro is also an intelligent watch that has many functions daily. Garman supports a safer payment system, and reproduces music, for example, Spotify and deeds. He will also show reminders and information on his smartphone, as well as the most common in a smartwatch.

4. Huawei Watch GT 2

Huawei GT2 is another good option at a very affordable price, which is the last offer they are doing with this model. GT2 is available for different wrist sizes. You can choose between 42 or 46-mm boxes. The clock has an attractive 1.39 -inch OLED touchscreen, which provides the precise activity. You can manage direct information and calls from the wrist and, which is very important, in the smallest model, up to 7 days of battery life and up to 14 in 46 mm.

Although it is not like Garman or Samsung in terms of tasks, the Huawei model is not far behind, and always keep in mind that the price is very low. In addition to any basic functions of any smart, it also contains a function of oxygen saturation in the blood.

GPS, 4GB memory, barometer, compass, heart rate meter, and multi -side port with 5 ATMs of water resistance, the Chinese manufacturer has some notable features.

5. Apple Watch 6 Series

Apple is one of the brands in which I work on forced marches during pandemic disease to add blood oxygen saturation control to its new series 6. So September 15, Apple confirmed that the function is its new 6 series.

Apple’s new watch is one of those who have personally tried, and it has been one that reads many times in many similar measurements. I am not sure the measurement is perfect, because I have not compared it to any medical equipment, but it doesn’t look bad. This version has improved new sensors and faster performance.

The sixth generation design is not much different from the previous version, so the 6 series can be described as a clock with a square box, and a curved touch screen that transmits even more bright and clear material.

It is still possible to change the bracelet and choose between any color and a large number of material straps. In addition, you can choose a stainless steel box, aluminum, or titanium in 40 or 44 mm. Sapphire glass will keep it without a single line.

In addition to any clock of this type, the new Apple has 32GB of heart rate control, accelerometer, gyroscope, ultimate or GPS, and other functions.

Bad thing? This is something that is still without understanding the truth in this brand. A battery life barely reaches a day if you are one of the people who constantly receive information and calls. And like all the products of this brand, a price that is much higher than its functions and quality.
