4-10 Alarms
Physiologic Alarms
Physiologic alarms indicate a life-threatening situation or a less urgent
situation such as heart rate beyond limits.
Warning
Do not rely exclusively on the audible alarm system for patient
monitoring. Adjustment of alarm volume to a low level during patient
monitoring may result in patient danger. Remember that the most
reliable method of patient monitoring combines close personal
surveillance with correct operation of monitoring equipment.
ST and QT related alarm messages appear at the Information Center
only.
Arrhythmia alarm chaining and customizing arrhythmia alarm settings are
described in the ECG and Arrhythmia Monitoring chapter. There are two
levels of arrhythmia analysis available: Basic and Enhanced. Enhanced
analysis includes Basic alarms.
The MX40 provides physiological alarms based on the settings at the
Information Center, Release N or later. Alarming is not active on the MX40
until it is configured via an active association with the Information Center.
In the following table, Red (***) alarms are listed alphabetically, followed by
the Yellow (**) alarms, and the Yellow (*) alarms.
