Setting or Adjusting Alarm Limits
Pulse oximetry alarm limits and delays are based either on factory default limits or
user-defined limits. The factory default settings for alarm limits are 100% for high
and 85% for low. For alarm delays, the factory default settings are 15 seconds for
alarm limit delay and 20 seconds for message alarm delay. Refer to the Alarms
chapter in the UCN Operations Manual for details concerning UCN alarm
operation.
When SpO
2
alarms are enabled, a bell symbol will be displayed between the
“SpO
2
” label and the SpO
2
measured saturation value. When any SpO
2
alarm is
detected, the displayed parameter value (item 1 in Figure 3-2 and Figure 3-3 on
page 3-3) will blink yellow if the alarm priority is Low or Medium, and will blink red
if the alarm priority is High. This is done independently of any other ECG or NIBP
alarm indications.
When SpO
2
alarms are enabled and the SpO
2
high limit is exceeded, the SpO
2
High=XXX key will blink in the color of the highest priority alarm present. When the
SpO
2
low limit is exceeded, the SpO
2
Low=XXX key will blink in the color of the
highest priority alarm present. Refer to Directory of Keys - UCW and Ultraview
1700 on page 1-1.
Refer to the Module Configuration Manager chapter of the UCN Operations
Manual for SpO
2
parameter tables that list available user settings and factory
defaults for this parameter.
ALM DELAY Key
This key sets the number of seconds the system will wait before it reports that an
alarm limit has been violated. When this feature is OFF, the key label will read
“ALM DELAY OFF”. When it is on, the label will read “ALM DELAY xx”, where “xx”
is the value, in seconds, of the delay.
To set the delay time:
1. Touch ALM DELAY xx (or ALM DELAY OFF).
2. Touch the up and down arrow keys until the value is set as desired. Possible
settings are OFF, 5, 10, 15, 20, 25, or 30 seconds.
