7. Measurement

For details, refer to “8. Operation”.

6. Displays the pulse rate.

7. Indicates the remaining battery level.

For details of the battery level, refer to “3. Preparation”.

8. Indicates the horizontal scale of the displayed SpO

waveform.

One scale corresponds to one second.

9. Displays the pulse wave.

The waveform size is adjusted automatically.

For details of the displayed messages and icons, refer to “11. Troubleshooting”

CAUTION

To display the PI value on the receiving monitor, the receiving monitor needs

to be compatible with the PI value display function. For details, refer to the

operation manual of the receiving monitor.

NOTE

The perfusion index (PI) is calculated by pulsatile signal divided by

apulsatile signal times 100, and indicates patient’s circulation condition at

the monitoring site.

This can be used to find a good perfusion site to attach the sensor. Also, it

can be used as diagnosis index to predict the patient’s critical condition

when at low perfusion.

(Reference)

Perfusion Index (PI) is a relative assessment of the pulse strength at the

monitoring site. It is a ratio of the pulsatile and the non-pulsatile blood flow at

the monitoring site. It can be used to find the most appropriate sensor

application site by finding the site with the highest PI. Perfusion Index (PI) is

displayed in the range from 0.02% to 20%, and the recommended value is

1% or above.
