3 Monitoring SpO2
35
• Manual mode - a single SpO
2
measurement is made when the Start SpO₂ SmartKey or the Start
SpO₂ menu item is selected. One set of values is then displayed with the time the measurement was
made.
• Automatic mode - a series of measurements is made with an interval between them. The interval
is selected using the
Repeat Time SmartKey or the Repeat menu item. The measurement starts
automatically when automatic mode is selected.
The values measured in manual mode or automatic mode will be displayed for one hour. After that the
values are regarded as invalid and are no longer displayed. Battery power usage will be appreciably
higher when measuring in continuous mode, in comparison to manual or automatic mode, resulting in
a reduced battery runtime.
Understanding SpO2 Numerics and Symbols
SpO2 Signal Quality Indicator
The SpO

numeric is displayed together with a signal quality indicator (if configured and enough space
is available) which gives an indication of the reliability of the displayed values.
The level to which the triangle is filled shows the quality of the signal; the indicator below shows a
medium signal quality, the signal quality is at a maximum when the triangle is completely filled.
