How to Measure Blood Oxygen Levels on Your KOSPET Smartwatch

Your blood oxygen level (blood oxygen saturation, or SpO2) refers to the amount of oxygen circulating in your blood. It is a crucial indicator of how well your heart and lungs are working. 

Oxygen levels in the blood stay relatively constant, even during workouts and sleep. A normal oxygen saturation level falls between 95% and 100% for most healthy children and adults. When your SpO2 is significantly lower than normal, it can affect your body's functioning.

Because the total amount of air you breathe tends to decrease during sleep, your nighttime blood oxygen level is usually lower than that of daytime. As a general rule, your SpO2 values are typically  above 90% during sleep . 

To be sure, everyone’s blood oxygen saturation is different. With a compatible KOSPET smart wearable on your wrist, you can monitor your blood oxygen levels on a day-to-day basis and check your SpO2 trends over time, assisting you to identify when there may be an indication of changes in your fitness and wellness.

Welcome to the  KOSPET official website  to discover smart wearable devices that care for your cardiovascular health around the clock. 

There are certain ways to test the oxygen saturation in your blood, one of which is to get a sample of blood and use laboratory chemistry equipment to measure SpO2. Yet, it may not be a practical approach for many users. Therefore, it is more common to turn to pulse oximeter technology that non-invasively measures your blood oxygen levels, leveraging leading-edge optical techniques. 

How does it work in practice? Deoxygenated blood, which returns to your lungs via your veins, is a slightly darker red colour than the fully oxygenated blood in your arteries and arterioles (small blood vessels that bring oxygenated blood to your tissues). You can estimate your SpO2 values by using the advanced VP60 sensor included in KOSPET wearable devices to measure the relative reflection of red and infrared light from your blood via your wrist and by observing how it varies with your heartbeats. 

It is important to note that KOSPET smartwatches and smart bands do not measure or display SpO2 values below 80%. The SpO2 data provided is not intended for medical purposes; neither is it intended to diagnose, treat, cure, or prevent any disease or condition.

Compatible KOSPET smart wearables also feature automatic blood oxygen measurement to periodically measure your blood oxygen levels day and night. After you enable such feature and set the measurement frequency (which ranges from 5 to 60 minutes) on your KOSPET smart device or via the compatible KOSPET FIT App, the wearable will measure your SpO2 when it detects that you are at still. 

Automatic blood oxygen measurement allows you to monitor your daily SpO2 levels under normal circumstances, which helps you understand how your body adapts to specific situations, such as high altitudes. 

If you are hiking at varying altitudes, it is suggested that you use the feature to monitor how your blood oxygen levels change and how your body adjusts to new altitudes.

In general, the lower your SpO2, the greater the risk. If your oxygen saturation level is  below 90%,  you may be at risk of developing hypoxemia, which can result from cardiopulmonary complications, sleep apnea, certain medicines, and high-altitude exposure. 

By turning on the Low Blood Oxygen Alert on your KOSPET smart wearable or via the KOSPET FIT App, you will receive an alert from your wrist when your SpO2 at rest (excluding sleep) falls below the set value (80%, 85%, or 90%) for 10 minutes. For outdoor enthusiasts like you, it is of vital importance to watch out for your SpO2 levels while reaching summits or blazing your path.
