Xiaomi Mi Band 8

Xiaomi Mi Band 8 NFC is the latest smart sports bracelet launched by Xiaomi. It not only has the functions of traditional sports bracelets, but also adds NFC functions and can measure blood pressure. So, how does Xiaomi Mi Band 8 NFC accurately measure blood pressure?

First of all, the user needs to wear the bracelet correctly on the wrist and ensure that there is no excessive sweat or moisture on the wrist, otherwise the accuracy of the measurement results may be affected. Next, the user needs to turn on the blood pressure measurement function on the bracelet and select the option to measure blood pressure. The bracelet will automatically start the measurement mode. The user only needs to gently press his finger on the fingerprint sensor on the bracelet and wait for a moment to complete the blood pressure measurement.

During the measurement process, users should keep their arms raised and their sitting posture stable, and avoid shaking or talking to avoid affecting the measurement results. The bracelet will sense the user's blood flow through infrared light signals and combine it with the built-in algorithm to measure blood pressure. After a few seconds, the bracelet will automatically display the user's blood pressure value.

It should be noted that although Xiaomi Mi Band 8 NFC has the function of measuring blood pressure, it can only provide a relatively accurate reference value and cannot replace professional medical equipment, nor can it be used for the diagnosis and treatment of diseases. If the user has abnormal blood pressure or needs more accurate blood pressure monitoring, it is recommended to consult a professional doctor and be equipped with relevant medical equipment.

In addition, in order to ensure the accuracy of measurement results, users must remember to regularly calibrate the blood pressure measurement function of the bracelet. The purpose of calibration is to adjust the measurement algorithm of the bracelet according to the user's actual blood pressure to improve the accuracy of the measurement results. Users can compare the bracelet with a professional blood pressure monitor and then perform calibration operations on the mobile APP.
