9.1 Overview
The mechanical activity of the heart causes arterial pulsation, and PR (pulse rate) value can be obtained by measuring this pulsation.
PR value can be obtained through SpO
2
measurement.
The average calculation of the heart rate is the direct average method. The refresh rate is every 1 second.
9.2 Display
