A dashed line (---) is displayed under , while the oxygen saturation is
measured and an SpO
2
value is calculated. In a few seconds the SpO

value is
displayed in place of the dashed line. As the patient’s oxygen saturation
changes, the SpO
2
value is updated continuously.
Figure 5-3 SpO

Monitoring Display
To the right of the SpO
2
value, a pleth bar and SpO
2
alarm indicator are dis-
played. The pleth bar should be observed for fluctuation. It is an indication of
pulsation detected by the sensor. The pleth bar should not be used as the sole
indicator of pulsation because it can be influenced by movement and artifact.
The symbol indicates no alarm is set.
Below the SpO
2
value is the pulse rate derived from the pulse oximetry.
