ST/AR Arrhythmia & ST Segment Monitoring
• Physician orders or medication specified limits.
You can make the following adjustments to ST alarm limits to accommodate the
clinical condition of individual patients:
• Turn all alarms off/on.
• Adjust the alarm limits:
– to specific high and low limits
– to Smart Limits (see the IntelliVue Information Center Instructions
for Use for information on Smart Limits)
– back to unit default settings.
You adjust the ST alarm limits in the ST Alarms Window. Each ST parameter
has its own alarm limit. The alarm is triggered when the ST value exceeds its
alarm limit for more than 1 minute. The alarm will be a yellow alarm.
When more than one ST parameter is in alarm, only one alarm message displays.
For multilead alarms when using an EASI transceiver, an alarm is generated if
two or more ST leads exceed the alarm limits. The default setting is +/-1.0. The
alarm message indicates the two leads that are in greatest violation of the limits,
for example, "**MULTI ST AVR, V6". If another lead becomes deviant, the
message changes but it is considered the same alarm (no new alarm sounds and
it is not listed as a new event).
See "Physiologic Alarms" on page 5-4 for a list of all ST alarms.
See IntelliVue Information Center Instructions for Use for specifics on alarm
management and behavior.
Make adjustments to ST alarms on the ST Alarms window at the Information
Center.
