best smartwatch with oxygen sensor

Have you ever considered having your personal fitness coach? Or are you often curious about your health and well-being? Well, in times like these, everyone should keep track of how well he is doing physically and physiologically. One of the best solutions for this is the best smartwatch with the oxygen sensor. 

The year 2020 has been so significant in terms of COVID-19. Almost everyone is concerned about his oxygen saturation levels, particularly if exposed to common flu or cold. Although I have potentially saved myself and my children from every lethal attack of this virus still, it had been a very primary question throughout this period that “Am I getting sufficient oxygen in my lungs and to the tissues?

To fight the odds and this increasing vagary, we need portable oximeters and blood pressure, monitors. Following this idea, the concept of smartwatches has come one step forward! Now, they have far more activities to offer than telling time alone.

Have you ever considered what blood oxygen saturation is?

First things first – oxygen is what keeps us alive. A protein in the human body, known as hemoglobin, absorbs oxygen from the body. Hence, when you breathe in, your lungs fill with oxygen while breathing out replaces the used oxygen. 

An oximeter, whether with a smartphone or smartwatch, has the ability to measure the amount of oxygen that your blood cells are carrying throughout your system. It then reports the saturation level as a percentage. Normal oxygen saturation level (SpO2) mainly stays between 95 to 100 percent. 

Who needs Oxygen Saturation Level Monitoring?

Well, if you feel just right and don’t feel sick or short of breath – you probably just don’t need the oxygen saturation test. These sensors are essential for climbers, divers, marathoners, and sports enthusiasts who undergo heavy exercising and may lead to dipping off their oxygen saturation levels.

Moreover, the SpO2 levels are super important for patients suffering from conditions such as certain respiratory diseases like sleep apnea, emphysema, COPD, or the pandemic Covid-19 disease itself.

All these conditions tend to increase your inability to breathe correctly. Hence, a patient with an oximeter does not need to catch the doctor even for the minor dips in its oxygen saturation levels.

How do the Oximeters Work for Us?

How they work totally depends on where you put them on the body or which body part are they particularly developed for. Consider the best smartwatch with the oxygen sensor, and it will act as a wrist-mounted device. Certain sensors are present underneath the face of your watch. 

Some oximeters, on the other hand, measure the amount of light that passes through the fingertip. The oxygen-deprived cells are darker in color, and the sensor then interprets this information in the form of the percentage of oxygen saturation.

The buying guide for smartwatches allows you to choose the best one for yourself while distinguishing between different factors. It would help if you keep in mind the following factors while buying a smartwatch for yourself:
