predetermined frequency or just per user request:
oHeart rate

oBlood pressure
oRespiration rate
oOxygen saturation
oBlood glucose
The watch also collects the source signal called PPG (photoplethysmography)
The data collected is stored in an internal memory in the smartwatch
The collected data is displayed at the watch screen
The collected data is also wirelessly sent to the user external receiver via bluetooth.
