Monitoring

12.1 Overview
The monitor measures the patients’ SpO
2
(oxygen saturation) and displays:
1. Pulse rate (PR) value in the ECG or SpO
2
parameter window.
2. PLETH waveform in the waveforms area.
3. Oxygen saturation (SpO
2
%) value in the SpO
2
parameter window.
The PR value is displayed in the ECG parameter window only if:
1. SpO
2
is selected from the HR FROM options in the ECG SETUP menu; or
2. AUTO is selected from the HR FROM options in the ECG SETUP menu and
no ECG signal is received.
For details, see
11.3 ECG Setup Menu
.
As the following figure shows, the PLETH waveform is located on the left while the
SpO
2
parameter window on the right. The SpO
2
value is displayed by percentage
and is followed by a perfusion indicator (pro rata with the pulse intensity). Besides,
the SpO
2
label at the upper left corner of the parameter window allows you to access
the SpO
2
SETUP menu.

Waveform and Parameter
PITCH TONE
The PITCH TONE function refers to the monitor’s capability to vary the pitch of the
heart rate tone or pulse rate tone with the change of the SpO
2
reading. This monitor
provides 22 pitch levels. The pitch rises as the SpO
2
reading increases toward 100%
and falls as it decreases. Although the tone pitch cannot be adjusted manually, the
tone volume can be adjusted by one of the following two ways, depending on the
setting of the HR FROM item in the ECG SETUP menu:
„ If the HR FROM is set to SPO2, you can adjust the PITCH TONE volume by
