Fault-Cause-Remedy

The Fabius MRI divides alarm messages into three
categories based on priority. Exclamation marks
indicate the priority. The alarm messages are dis-
played on colored background if the option "Color
display" is enabled:
!!! Warning (red)
!! Caution (yellow)
! Advisory (white)
Internal priority numbers, see page 119, for the
ranking within an alarm category are written below
in brackets, e.g. (23 / 31).
Priority Alarm Message
!!! AIRWAY PRESSURE HIGH
(31)
!! / !!! APNEA FLOW
(23/31)
!! / !!! APNEA PRESSURE
(23/31)
1) APNEA FLOW alarm priorities are based on alarm duration and ventilation mode:
In Volume Control, Pressure Control, SIMV/PS with Freq ≥6, or Pressure Support with Apnea Ventilation OFF:
Caution = V <20 mL for >15 seconds
T
Warning = V < 20 mL for >30 seconds
T
In ManSpont, SIMV/PS with Freq <6, or Pressure Support with Apnea Ventilation ON:
Caution = V <20 mL for >30 seconds
T
Warning = V <20 mL for >60 seconds
T
2) APNEA PRESSURE alarm priorities are based on alarm duration and ventilation mode:
In Volume Control, Pressure Control, SIMV/PS with Freq ≥6, or Pressure Support with Apnea Ventilation OFF:
Caution = P does not cross the pressure threshold for >15 seconds
AW
Warning = P does not cross the pressure threshold for >30 seconds
AW
In ManSpont, SIMV/PS with Freq <6, or Pressure Support with Apnea Ventilation ON:
Caution = P does not cross the pressure threshold for >30 seconds
AW
Warning = P does not cross the pressure threshold for >60 seconds
AW
162
high priority
medium priority
low priority
Probable Cause
Upper alarm limit for airway
pressure has been exceeded,
ventilation hose is kinked.
Alarm limit has been set too
low.
1)
Breathing/ventilation stops.
Breathing circuit disconnected
or leakage.
2)
Breathing/ventilation stops.
Breathing circuit disconnected
or leakage.
Remedy
Check hose system on anes-
thesia machine.
Check breathing circuit or
alarm limit value.
Check ventilator.
Check breathing circuit.
Check ventilator.
Check breathing circuit.
