6 Alarms and troubleshooting
WARNINGS
•
You should check that the default thresholds set for activation of the alarms are
appropriate before using the ventilator on a patient.
•
If you set the alarm thresholds at extreme levels you risk making the alarms system
ineffective.
There are three types of alarm:
•
Ventilation monitoring alarms
•
Technical alarms
•
Servicing alarms.
Each alarm has a priority level that cannot be changed by the user:
•
High priority
•
Medium priority
•
Low priority.
In addition, each alarm may be either:
•
Permanently stopped (by pressing the button)
•
Temporarily stopped (the audible signal is muted for two minutes, but the visual symbol
remains displayed on the screen)
•
Not stopped at all.
6.1 Alarm signal
When an alarm is triggered, this is indicated by:
•
The audible signal sounding: this depends on the priority of the alarm. It is produced by two
buzzers and a digital sound generator.
•
Signals appearing on the screen (e.g. for the High Pressure alarm):
•
One of the LEDs on the LED panel flashing (red or orange, depending on the priority of the
alarm).
Pressing the button mutes the audible signal but the symbol remains displayed on the
screen.
Note:
It is possible to mute the audible signal of an alarm for two minutes simply by pressing
the Alarm Silence button. The symbol will then start to flash. During this period, any
alarm triggered will be indicated only by the flashing alarm name. Pressing again unmutes
the alarm.
