Fault – Cause – Remedy
EvitaXL shows alarm messages in hierarchical order in the
alarm display field.
If two faults are detected at the same time, for example, the
more critical of the two will be displayed.
The priority of the alarm messages is indicated by exclamation
marks:
!!! = Alarm: Top priority message
!! = Caution: Medium priority message
! = Advisory: Low priority message
Messages are listed in alphabetical order in the following
table. The table should help to identify and remedy the cause
of an alarm more quickly. The various causes and remedies
should be worked through in the order listed until the problem
has been remedied.
Message Cause Remedy
Air supply down !!! Air supply pressure too low. Make sure supply pressure is greater than
3 bar.
Air supply down ! Air supply pressure too low.
Air supply pressure not required when
FiO2 = 100 Vol. %.
Make sure supply pressure is greater than
3 bar.
Air supply pressure high !! Air supply pressure too high. Make sure supply pressure is less than
6 bar.
Air supply pressure high ! Air supply pressure too high.
Air supply not required for
FiO2 = 100 Vol.%.
Airway obstructed? !!! The ventilator applies only a very small
volume with each mechanical stroke,
e.g. because the tube is blocked.
Patient "fights" against the mechanical
strokes in pressure-controlled ventilation,
with the result that the set inspiratory
pressure is reached with only a very small
volume.
Airway pressure high !!! The upper alarm limit for the airway
pressure has been exceeded. The patient
is "fighting" the ventilator or coughing.
Make sure supply pressure is less than
6 bar.
Check condition of patient, check tube.
Check condition of patient,
check ventilator settings.
Check patient condition.
Check ventilation pattern.
Correct alarm limits if necessary.
Ventilation hose buckled. Check hose system and tube.
Airway pressure low !!! Leaking cuff? Inflate cuff and check for leaks.
Leak or disconnection. Check hose system for tight connections.
Check that the expiration valve is properly
engaged.
Ambient pressure sensor? !! Ambient pressure sensor faulty. Note: The ventilator functions are not
affected. Device can not be used in
helicopters or aircraft.
