1. Press the SELECT softkey until highlighting the SPD sensitivity setting. The default setting
of one (1) is the most sensitive to patterns of desaturation, but may also lead to more
alarms.

2. Use the ADJUST UP key to select a setting that is less sensitive to desaturation patterns,
that also results in fewer alarms. The setting of three (3) is the least sensitive to patterns of
desaturation.
3. Press the EXIT softkey to save your selection.
Using the Pulse Rate Delay Alarm Management Feature
How the Pulse Rate Delay Feature Works
The oximeter monitors pulse rate by determining the number of pleth waves over
unit time. With traditional alarm management, upper and lower alarm limits are set
for monitoring pulse rate. When the pulse rate fluctuates near an alarm limit, the
alarm sounds each time it violates an alarm limit. Use the Pulse Rate Delay feature to
distinguish clinically significant events from minor and brief pulse rate limit
violations that result in nuisance alarms. The Pulse Rate Delay feature allows a period
of threshold violation before the pulse rate alarm sounds. Thus, the Pulse Rate Delay
feature distinguishes clinically significant events from minor and brief pulse rate limit
violations that may result in nuisance alarms.
To use the Pulse Rate Delay feature, set the traditional alarm management upper and
lower pulse rate alarm limits. Then, set the Pulse Rate Delay. The Pulse Rate Delay
limit controls the time the pulse rate level crosses either limit before an audible alarm
sounds.
To set the alarm delay
1. With the oximeter in the normal monitoring mode, press the LIMITS softkey.
2. Press SELECT softkey until highlighting the alarm delay setting, highlighting the default
setting of OFF.
3. Use the ADJUST UP key to select a five (5) second alarm delay or a ten (10) second alarm
delay.
