Alarm status — 

This status type identifies alarm conditions from highest to lowest 

priority. If multiple alarms occur while users are choosing menu options, the vertical 
alarm list of messages appears with the highest priority alarms at the top. If more 
than three alarms are active, the list collapses into a single VIEW ALL ALARMS line 
containing the total number of active alarms. Each alarm contains a MORE INFO 
button. Pressing the MORE INFO button provides a detailed explanation and any 
corrective action required. 

a.

High priority alarms — 

Alarm message appears on flashing red back-

ground. High priority alarms appear first when multiple alarms occur simulta-
neously. 

b.

Medium priority alarms — 

Alarm message appears on flashing yellow 

background. Medium priority alarms appear after high priority alarms and 
before low priority alarms.

c.

Low priority alarms — 

Alarm message appears on steady yellow back-

ground. Low priority alarms appear after high or medium priority alarms.

6.4.3

Alarm Management and Status Messages

The status field at the top of the monitoring screen contains information describ-
ing overall monitoring system status and any active alarms. If multiple alarms 
occur during user interaction with a menu or dialog box, the list of alarm mes-
sages collapses to a single line listing the total number of alarms currently active. 
Cancellation or dismissal of an alarm message requires user intervention, 
whereas status messages do not. The message identifies the alarm or status. If 
it is an alarm, it offers users a MORE INFO button, which when pressed, provides 
detailed data and a means to correct the situation or clear the alarm. 

The monitoring system comes with factory default alarm limit thresholds for 
adult-pediatric patients and for neonate patients. Reference 

To set institutional 

defaults

, p. 10-6. Institutions may opt for setting institutional default settings 

to override the factory defaults. In addition, users may also temporarily change 
alarm limits. Any temporary changes to alarm limit thresholds revert back to 
default alarm limit settings after power-off. 

Note:

There are no delays associated with any alarm conditions that exceed ten (10) seconds 
unless otherwise specified.
