Alarms Operation
3.19.4 Alarm Violations
Alarms are classified by severity: Warnings (Priority 1) and Cautions (Priority 2).
Warnings are HIGH priority and activate a red LED. Cautions are lower priority and activate
a yellow LED on the keypad.
A. Parameter Alarms
An alarm condition exists if the parameter is equal to or is outside the high/low limit range.
When an alarm limit is violated, the following actions occur:
The red or yellow alarm LED flashes, according to the priority of the alarm.
An alarm tone is sounded (unless it is muted with the MUTE ALL key), according to
the priority of the alarm.
The recorder prints the currently selected waveform (if Record On Alarm is selected
from the Recorder menu).
NOTE: On the waveform printouts that are caused by alarm
situations, a bar is printed above the alarming area. On
trend printouts, the value that has caused an alarm is
printed with square brackets around it. If the recorder is
printing a waveform and an alarm situation occurs, the
currently printing waveform will be aborted and the new
alarm waveform printout will be printed.
The data for the violated parameter is displayed in reverse graphics in the parameter
window.
The display indicates the priority of the alarm as follows:
On color displays:
Priority 1 alarm data is shown in inverse video with red background.
Priority 2 alarm data is shown in inverse video with yellow background.
On monochrome displays:
Priority 1 alarm data is shown in inverse video with background at full brightness.
Priority 2 alarm data is shown in inverse video with background at half brightness.
If a parameter is being monitored but data is not being displayed, an alarm message will be
posted at the top of the display.
B. Heart Rate Fault Alarm
The Heart Rate Fault Alarm occurs if the selected heart rate source is no longer able to detect
a heart rate. This may be due to an ECG lead fault, a problem with an SpO2 sensor, or
various other reasons. This alarm is only active if a low heart rate limit is set. The alarm
operation is the same as for a parameter alarm. A further message from a lead fault or SpO2 fault may be present to help diagnose the problem. The heart rate alarm is a Priority 1 alarm.
NOTE: Only the value displayed in the heart rate window is used
to determine heart rate alarm conditions.
