3 Alarms
Alarm Delays
There is a delay between a physiological event at the measurement site and the corresponding alarm
indication at the monitor. This delay has two components:
The general measurement delay time is the time between the occurrence of the
physiological event and when this event is represented by the displayed numerical values.
This delay depends on the algorithmic processing and, for certain measurements (SpO
BIS), on the configured averaging time. The longer the averaging time configured, the longer the
time needed until the numerical values reflect the physiological event.
The time between the displayed numerical values crossing an alarm limit and the alarm
indication on the monitor. This delay is the sum of the alarm delay configured for the specific
measurement plus the system alarm delay. The system alarm delay is the processing time the
system needs for any alarm on the monitor to be indicated after the measurement has triggered the
alarm. See the performance specifications in the Specifications chapter for the system alarm delay
specification.
The alarm delay configured for a specific measurement is normally a fixed time. For SpO
possible to configure a Smart Alarm Delay that is calculated using an intelligent algorithm. See "Smart
Alarm Delays" on page 195 in the SpO
Multiple Alarms
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. Your monitor
may be configured to increase alarm indicator volume automatically during the time when the alarm is
not acknowledged.

Visual Alarm Indicators

WARNING
No alarms are available on an X2 when connected to a host monitor (
indicated). Alarms become active again as soon as the X2 is disconnected from the host monitor.
Alarm fields and other visual alarm indicators are disabled on an X2 when connected to a host
monitor. The only visual alarm indication is provided by the alarm lamps, which are controlled by
the host monitor.
Alarm Message
An alarm message text appears in the alarm status area at the top of the screen indicating the source of
the alarm. If more than one measurement is in an alarm condition, the message changes every two
seconds, and has an arrow ( ) at the side. The background color of the alarm message matches the
alarm priority: red for red alarms, yellow for yellow alarms, light blue for standard INOPs, red for red
INOPs and yellow for yellow INOPs. The asterisk symbols (
