Alarms
Alarms are provided to alert you to a change in the patient’s condition. If alarms are enabled, alarm
limits appear next to the pressure value. Invasive pressure alarms are all categorized as “non-latching”
alarms, meaning they are automatically removed when their alarm condition no longer exists. Table 18
details invasive pressure alarms.
Table 18 Invasive Pressure Red/Yellow Physiological Alarms
Each pressure label has its own unique set of default alarm limits which are set in Configuration mode.
See “Configuration” on page 181 for details. If the alarm is from a pulsatile source, the source is
displayed above the alarm limits. If alarms are off, the Alarms Off symbol replaces the limits.
If a wave becomes non-pulsatile, the measurement will become mean only and be compared to the
current source (which may be systolic or diastolic) and alarm limits.
WARNING Make sure you enable/disable and set alarm limits for the correct label. These settings apply to that
particular label only. Changing the label might change the alarm limits.
