Alarm signals
Alarm system continuously monitors the operating parameters of the device affecting to the
safety of the patient, and indicates the situation where the intervention of the staff is required.
Forms of the alarm signals:
1. Sound alarm. Volume is growing by 10 % every minute in presence of alarm situation;
2. Red indicator “Alarm” on the top side of device enclosure;
3. Message on the screen with the name of the alarm.
Depending on the risk for the patient alarms are classified into three groups:
1. Low priority alarm (green message on the screen);
2. Medium priority alarm (sound alarm, “Alarm” indicator and yellow message on the screen);
3. High priority alarm (sound alarm of the higher frequency and intensity, “Alarm” indicator
and red message on the screen).
Depending on the cause of the occurrence and further consequences, the alarms are divided in-
to 2 groups:
1. Physiological alarms -alarms that occur due to patient condition one or more physiological
parameters monitoring the patient exceed the predefined alarm limit;
2. Technical alarms - alarms that that occur due to the device or alarm system conditions;
If the alarm is triggered check the patient condition to identify and eliminate the cause of the
alarm situation. After removing the cause of the alarm, the device automatically disables the
alarm. If several alarm conditions exist, the device switches to the next alarm situation in order
of their priority.
In the situation of several alarm conditions at the same time alarm with the highest priority is ac-
tivated. Messages about other alarms (up to 6 messages) are displayed in the "Alarm List". The
alarm log stores information about all current and previous alarms. The lists of alarm messages
are stated in
Tables 4.15 – 4.17 , where the text of the alarm message, the short message in
brackets which is displayed in the "Alarm List" and the alarm log, as well as the response of the
device and operator actions are mentioned. The list of informational messages is stated in
Ta-
ble 4.18.
For convenience of the personnel audible alarm can be temporarily disable for 120 s by press-
ing of the button or sound mute icon . The LED above the button informs the personnel
about temporarily disabling of the audible alarm. Disabling of the sound alarms does not result
in disabling of visual alarms.
Before starting the ventilation make sure that alarm system works properly by checking discon-
nection or occlusion alarm.
To check the disconnection alarm, assemble the breathing circuit in
accordance with Figure 3.6 and disconnect the breathing bag from the tee of the patient. The
alarm should appear in 30 seconds.
To check the occlusion alarm, assemble the breathing circuit according to the Figure 3.6 and
block the output port of expiration valve (Figure 2.1 position 20). The alarm should appear in 30
seconds.
The ventilator makes self-test after switching on and within the whole operation process. If the
critical failures occurred during initial test the ventilator switches to emergency mode. In this
case normal ventilation does not start and the ventilator’s replacement is required. If the critical
failures occurred during operation the emergency alarm issues but the ventilator continues ven-
tilation process with partial loss of functionality. In case of fatal failure the ventilator could switch
to full emergency mode (FEM) and stop the ventilation. The urgent replacement of ventilator or
application of alternative ventilation method is required. For further information refer to it. 4.17.6.
