Using the Monitor
that are derived from the SpO
2
signal. A tone sounds at a
rate corresponding to the SpO
2
saturation level. The pitch is
highest at 100% oxygen saturation and becomes a little
lower with each 1% decrease in saturation level. The
Monitor can display a pulse amplitude bar and a
plethysmographic waveform on the LCD (25). The pulse
amplitude bar graph is proportional to the arterial blood
flow. The artifact indicator LED (24) lights continuously when
the Monitor detects motion sufficient enough to affect
readings.
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.
If you select the Alarms button, the Alarms menu appears.
This menu is used to adjust the violation limits for BP and
SpO
2
. Refer to “Alarms Button” in the “Using the Menu
System” section.
If you select the Suspend button, the SpO
2
alarm is
suspended for 2 minutes and then the PRO Monitor returns
to normal SpO
2
monitoring. A message informing the user
that SpO
2
is suspending appears in Area 2 and dashes
appear in the SpO
2
LED while the SpO
2
alarm suspend is
counting down. Selecting Cancel will cancel the SpO
2
alarm
suspension and return to monitoring SpO
2
.
If the Monitor is unable to detect a pulse for 10 seconds
during normal SpO
2
monitoring, the values in the LED flash,
