The Redmi Watch 3 Active doesn’t support blood pressure monitoring.
Blood pressure monitoring on smart bands involves using optical sensors to estimate blood pressure indirectly rather than directly measuring it like traditional blood pressure cuffs.
Blood pressure measurements from smart bands will not be as accurate as those from traditional cuff-based monitors. Factors such as sensor quality, skin contact, and algorithm accuracy can affect readings.
Please consider consulting healthcare professionals for accurate and reliable blood pressure measurements, especially for medical decisions.
