If you’re a big fan of smartwatches, you’re probably aware that SpO2 monitoring is now a standard feature. It’s beneficial when tracking your sleep or when you’re at a high altitude. It can also detect sleep apnea and other respiratory conditions requiring medical treatment. We’ve compiled a list of the best blood oxygen monitoring smartwatches.

What do you understand by SpO2?
SpO2 sensors, also called pulse oximeters, measure blood oxygen levels or oxygen saturation in your blood. It is undoubtedly one of the most critical vital signs to monitor in a medical setting because, as you may know, oxygen is essential to humans, and its absence can be fatal. As a result, wearables such as activity trackers and smartwatches now include the technology to measure this vital health indicator. In this sense, the smartwatch is concerned with Sp02, or peripheral oxygen saturation, which is critical for continuous blood oxygen level assessment.
SpO2 levels are measured in percentages, and a standard level should be between 95 and 100 per cent for most people. Normal values might range from 88-92 per cent for people with chronic lung diseases such as chronic obstructive pulmonary disease.

How does a smartwatch with SpO2 measure blood oxygen?
Another form of SpO2 technology used by smartwatches is reflectance pulse oximetry, which simply counts light reflected rather than light flowing through the body. In contrast to the transmissive approach, blood oxygen levels can be measured in different areas of the body, such as the chest and wrist.
The light transmitted to the human surface is reflected from the subcutaneous tissue or bone to the wristwatch sensor, which uses the difference between the light emitted and reflected to measure blood oxygen level. As a result, smartwatches can use it to detect blood SpO2.
It’s crucial to note that a lower measurement can occasionally be caused by the device not being used or appropriately calibrated. If you have a smartwatch that shows you have low SpO2 readings, it’s always a good idea to seek medical help right away if you’re feeling sick or short of breath.

Conclusion
While it is convenient to check your blood oxygen level on your wrist at any time, the reflectance-based oximetry used by smartwatches is less developed than the transmissive approach. Aside from that, detecting blood oxygen levels on smartwatches falls short of clinical standards.
The SpO2 monitor in smartwatches, in reality, has no medical accreditation, indicating that it is not intended for diagnosis or wellness. It’s more for fitness purposes because the findings are usually inaccurate. Stay still when taking SpO2 measures on your smartwatch to achieve the best results.
