Alarms and Error Conditions
Service Manual 11-5
Alarm Prioritization
Alarms have an assigned priority. Stacked alarms display in order of criticality
and priority. Reference
Message Types , p. 6-11, for details on high, medium,
and low priority alarms. Occasionally, the monitoring screen field contains one
or more prompts or error messages. Stacked alarms display in order of critical-
ity and priority. High priority messages appear above low priority messages.
Alarms of the same priority appear in order of occurrence. If the caregiver does
not resolve the issue and clear the condition, the monitoring system may esca-
late the alarm by increasing the frequency of the alarm.
