Figure 4-17 SpO

Setup

 Sensitivity

The SpO

reading is the average of data collected within a specific time. You can set

Sensitivity to Low, Medium or High via the menu. The higher the sensitivity is, the quicker

the pulse oximeter responds to the changes in the patient’s oxygen saturation level. Contrarily,

the lower the sensitivity is, the slower the pulse oximeter responds to the changes in the

patient’s oxygen saturation level, but the measurement accuracy will be improved. When a

critical patient is monitored, selecting high sensitivity will help to understand the patient’s

state.

 Sensor Off

You can configure the alarm level for SpO

Sensor Off to Low or High.

 Alarm Setup

Access Alarm Setup and you can see the menu below:

Figure 4-18 Alarm Setup (for monitor with recorder)

 Alarm Silence

You can set this item to ON or OFF. If the item is ON, you can turn off the audio system by

pressing the SILENCE button on the front panel for more than 2s. In this case, all sounds

including the alarm sound, key sound and sphygmic sound coming from the monitor will be

 Alarm Record (only available for the monitor outfitted with a recorder)

By configuring Alarm Record, the function of automatically outputting the alarm

information in case of any physiological alarm can be enabled or disabled. If the item is ON,

the monitor will automatically print out the alarm information once any physiological alarm

is triggered. If the item is OFF, the monitor will not automatically output the alarm

information.
