The following is a description of the SPO2 Menu options:
a. SIZE. (See Figure 4-12) Selecting this menu option provides the operator with the
ability to change the size of the SpO2 pulse waveform. The options are 10%, 20%,
40% (default), 60%, 80% and 100%.

b. HR SOURCE. Selecting this menu option allows the selection of the source to be used
for the heart-rate display in the ECG area. The options are AUTO, ECG (default), ART
(arterial pressure), SPO2 and NIBP.
This menu option is identical to, and interactive with, similarly named menu options
under ECG and NIBP.
c. HR TONE SRCE. Selecting this menu option selects the Heart Rate tone source. The
options are QRS, SPO2 and OFF (default). When the source is the QRS, the tone
sounds at the detection of QRS from the ECG parameter. When the source is the SpO2,
the tone sounds at the detection of the pulse from the SpO2 parameter.
The pulse tone is modulated by the SpO2 value. The pitch will be at the lowest
frequency when its value is at the low end of scale.
This menu option is identical to, and interactive with, the HR TONE SOURCE option
in the SOUND ADJUST and ECG Menus.
d. RETURN. Selecting this menu option will return the monitor to the Normal Screen.
4.3.4 Alarm Limits. Alarm Limits may be set two ways. To set the Alarm Limits for every available
parameter, from the Normal Screen (with no icons highlighted), press the ALARMS SCREEN Menu-
Select Key. To set the Alarm Limits for SpO2 only, highlight the SpO2 Icon and press the ALARMS
SCREEN Menu-Select Key to access the individual parameter Alarm Limits Box. The range of Alarm
Limits for SpO2 is 50 to 100%.
4.3.5 Trended Data. For complete information on the trending of patient SpO2 data, see Section 5:
Printing and Trending.
4.3.6
SpO2 Messages. The following is a list of messages that may be displayed during SpO2
monitoring:
NOTE
Invasive Pressure is not available with this system. If ART is selected as the HR SOURCE a
Warning box appears that informs the operator that this option is not available.
BAD PROBE The monitor has sensed a shorted or open connector in the sensor.
Contact Invivo Technical Service for further assistance.
HIGH LIGHT There is too much light passing through the tissue at the present
sensor site. Move the sensor to an area with thicker tissue.
