Alarms
The alarm information here applies to all measurements. Measurement-specific alarm information is
contained in the sections on individual measurements.
The fetal monitor has three alarm levels: red, yellow, and INOP.
Red and yellow alarms are patient alarms. A red alarm indicates high priority, such as a potentially life
threatening situation (for example, SpO
2
below the desaturation alarm limit). A yellow alarm indicates
a lower priority alarm (for example, a fetal heart rate alarm limit violation).
INOPs are technical alarms. They indicate that the monitor cannot measure and therefore not detect
critical conditions reliably. If an INOP interrupts monitoring and alarm detection (for example,
MECG
LEADS OFF ), the monitor places a question mark in place of the measurement numeric and sounds an
audible tone. INOPs without this tone indicate that there may be a problem with the reliability of the
data, but that monitoring is not interrupted.
Alarms are indicated after the specified alarm delay time. This is made up of the system delay time plus
the trigger delay time for the individual measurement. See the Specifications section for details.
If more than one alarm is active, the alarm messages are shown in the alarm status area in succession.
An arrow symbol next to the alarm message informs you that more than one message is active.
The monitor sounds an audible indicator for the highest priority alarm. If more than one alarm
condition is active in the same measurement, the monitor announces the most severe.
WARNING
Alarm systems of the monitor and those of the connected OB system are independent and not
synchronized.
Alarm Mode
You can configure the alarm mode for your fetal monitor. There are two possible modes:
•
All
: alarms and INOPs are enabled, with all audible and visual indicators active.
• INOP Only only INOPs are enabled, with audible and visual indication active. This is the default
alarm mode.
