Does Xiaomi Smart Band 8 support blood oxygen detection? Does it support all-day blood oxygen testing?

Support. After waking up the strip, open the blood oxygen application in the application list to manually measure the blood oxygen saturation. After the measurement is completed, the measurement result will be displayed on the strip.
Measurement instructions:
Wear the device one finger away from your wrist bone, wear the band tightly, with the screen of the band facing upwards, and keep it still;
Wear it tightly and keep still during the measurement. If the movement range is too large during the measurement, a prompt will appear. Please operate correctly according to the prompt;
During the measurement process, incoming calls, alarm clocks and other reminders will interrupt the measurement;
Skin characteristics, hair, low temperature and other factors may affect the measurement results;
The measurement results are for reference only and are not used as a basis for medical diagnosis.
Xiaomi Smart Band 8 supports all-day blood oxygen detection. After being turned on, the band will automatically measure blood oxygen saturation when it detects continued inactivity, but the battery life will also be reduced.
