The reliability of the blood oxygen monitoring feature on the Redmi Watch 5 Active can be assessed based on comparisons with other devices and its performance in various conditions.
Comparative Accuracy:
In a comparison with a fingertip pulse oximeter, the Redmi Watch 5 Active showed a minor difference in blood oxygen readings, typically within 1% of the oximeter's results[1]. This suggests that while there might be slight variations, the watch generally provides reliable blood oxygen measurements.
Performance and Limitations:
The Redmi Watch 5 Active uses photoplethysmography (PPG) technology for health monitoring, which is common in wrist-based devices. While PPG sensors can provide accurate readings under stable conditions, they may be less reliable during activities that cause significant wrist movement or pressure, such as cycling[3]. However, for general monitoring, the watch's blood oxygen feature is considered reliable for casual use.
User Experience:
Users have found the Redmi Watch 5 Active to be a reliable budget fitness companion, with its health tracking features, including blood oxygen monitoring, providing useful insights for fitness enthusiasts[7]. However, it's important to note that these readings should be used for reference rather than for medical purposes[6].
Conclusion:
Overall, the blood oxygen monitoring feature on the Redmi Watch 5 Active is reliable for casual use and provides generally accurate readings compared to more precise medical devices. However, it should not be relied upon for critical medical assessments.
