that are derived from the SpO
2
signal. A tone sounds at a
rate corresponding to the pulse rate and at a pitch
corresponding to the SpO
2
saturation level. The pitch is
highest at 100% oxygen saturation, and it becomes lower as
the saturation level falls. The Monitor can also display a
pulse amplitude bar and a plethysmographic waveform on
the LCD (10). The pulse amplitude bar graph is proportional
to the arterial blood flow.
Audible and visible alarms occur when SpO
2
levels are
outside the alarm limits. When a limit alarm occurs, a
message appears in Area 2 of the LCD display.
