When it comes to wearable technology, modern smartwatches are not just glorified timekeepers; they serve as powerful health monitoring devices packed with innovative features. The Samsung Galaxy Watch Active 2 is one such smartwatch that promises an array of health tracking functionalities. One of the most queried capabilities among potential users is, “Can the Samsung Active 2 measure blood oxygen?” This article delves deep into this question, exploring the technology behind the device, its features, accuracy, and comparison with other products in the market.
Understanding Blood Oxygen Measurement
Before discussing whether the Samsung Active 2 can measure blood oxygen levels, it’s important to understand what blood oxygen measurement involves.
What is Blood Oxygen Saturation?
Blood oxygen saturation, commonly referred to as SpO2, indicates the percentage of oxygen-saturated hemoglobin in your blood. Normal levels typically range from 95% to 100%. Measuring blood oxygen levels is vital because it helps monitor how well oxygen is being transported throughout the body, which can be crucial for individuals with respiratory issues or conditions such as asthma, COPD, or sleep apnea.
How Are Blood Oxygen Levels Measured?
Medical professionals often use devices called pulse oximeters to measure blood oxygen levels non-invasively. These devices work by shining a light through the skin, usually placed on a fingertip, and measuring how much light passes through. The difference helps calculate the levels of oxygen in your blood. With the rise of wearable technology, smartwatches have begun incorporating similar functions but often with variations in accuracy and methodology.

Can the Samsung Active 2 Measure Blood Oxygen Levels?
Answering the burning question: Can the Samsung Active 2 truly measure blood oxygen levels? The short answer is: Yes, but with some caveats.
Understanding the SpO2 Feature in Active 2
The Galaxy Watch Active 2 includes a built-in SpO2 sensor, designed to provide users with insights into their blood oxygen saturation levels. This feature, however, became available after a software update in 2020. Initially, the watch did not have the capability pre-launch, leading to some confusion among users.
How Does It Work?
The Active 2 uses optical sensors similar to those in pulse oximeters. When activated, the watch emits a green and red light through the skin of the wrist to measure the oxygen saturation in the blood. The results can be accessed via the Samsung Health app, where users can also track their health trends over time.
Accuracy of Blood Oxygen Measurement
While the Active 2 can measure SpO2 levels, it’s important to note that the accuracy of these readings can vary based on several factors:
- Skin Tone: The color of the skin can impact the readings, as darker skin tones may reflect light differently than lighter tones.
- Fitness Levels: People who are more physically fit or engage in regular aerobic activities may experience fluctuations in blood oxygen levels that could lead to variable readings.
- Placement and Fit: The wrist watch must fit snugly; otherwise, the light may not penetrate effectively, leading to inaccurate measurements.
Limitations of the Blood Oxygen Monitoring Feature
While the blood oxygen measurement feature is indeed a valuable addition to the Samsung Active 2, it is vital to acknowledge its limitations:
- Not a Medical Device: The Active 2 is not certified as a medical-grade device, which means that the readings should not be used as a substitute for professional medical advice.
- Occasional Inaccuracies: Users have reported that readings can sometimes be erroneous or inconsistent, emphasizing the need to interpret readings with caution.
Comparing Samsung Active 2 with Other Smartwatches
In the ever-growing market of smartwatches equipped with health-monitoring features, comparison is crucial for users who want the best technology. Let’s look at how the Samsung Galaxy Watch Active 2 compares with other reputable smartwatches.
| Feature | Samsung Galaxy Watch Active 2 | Apple Watch Series 6 | Fitbit Sense |
