Calculation Method for Displayed Values

<Pulse level meter>

The pulse level meter displays the transmitted light amount ratio calculated by the following equation. The pulse level is indicated in eight levels (0 to 15%, full scale if over 10%).

Pulse level (%) =

Transmitted light amount that varies due to the pulse

x 100

------------------------------------------------------------------------------------------------------------------Transmitted light amount that does not vary due to the pulse

<Oxygen saturation (SpO2)>

Updates the moving average of the oxygen saturation over the last 12 seconds at one-second intervals.

<Pulse rate (P.R.)>

Updates the moving average of the last 8 pulse rates at one-second intervals.
