Pulse rate derived from SpO
2
appears in the Pulse Rate
window, and the SpO
2
pulse indicator flashes
synchronization with the real-time pulse rate measurements
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 displays a pulse bar
graph. The pulse bar graph is proportional to the signal
quality. The artifact indicator LED (24) illuminates when low
perfusion or poor signal quality is detected.
Audible and visible alarms occur when SpO
2
levels are
outside the alarm limits. When a limit alarm occurs, an alarm
message appears in SpO
2
window.
Note: Limit alarms, printing, and trending are not available
for the first 10 seconds of SpO
2
monitoring.
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
.
