TROUBLE SHOUTING
PROBLEM
POTENTIAL CAUSE
CORRECTIVE ACTION
High PEEP
1. Diaphragm of the expiratory
valve stuck.
2.
Obstruction of the patient’s
circuit.
3. Defective PEEP
electrovalve.
1. Replace the diaphragm of the
expiratory valve.
2. Check the patient’s circuit.
3. Check the operation of the
electrovalve.
Low PEEP
1. Leaks in the patient’s circuit.
2. Damaged
expiratory valve.
3. Leaks in the internal
pneumatic circuit.
4. Defective PEEP
electrovalve.
1. Check the patient’s circuit.
2. Check expiratory valve.
3.
Check the internal pneumatic circuit.
4. Check the operation of the
electrovalve.
Nebulizer without
flow
1. Inspiratory flow lower than 7
L/min.
2.
Disconnection in the internal
pneumatic circuit.
3. Obstruction in nebulizer.
4. Damaged solenoid valve.
1. Increase the inspiratory flow.
2.
Check the internal pneumatic circuit.
3.
Check permeability of the nebulizer
capillary.
4. Check operation of the solenoid
valve.
FiO2 different from
% FIO2
measurement
1. Decalibrated air or oxygen
proportional valves.
2. Decalibrated pressure
regulators.
3. Decalibrated oxygen
analyzer.
1. Recalibrate proportional valves, and
then recalibrate the measurement
parameters of the device.
2. Check the calibration of the
pressure regulators. Then,
recalibrate the device completely.
3. Calibrate oxygen analyzer.
Blower failure
1. Back fan disconnected or
blocked.
2. Damaged back fan.
1. Check fan and check connections.
2. Replace fan by
one with the same
features.
Low battery charge
1. Low battery charge.
2. Damaged battery.
3. Battery disconnected.
4. Electrical failure.
1. Charge the battery for 12 hours, and
if it does not become charged,
replace with new one.
2.
Replace the battery with a new one.
3. Check the battery connections.
4. Check charge voltage (13 0.5 V).
Screen does not
work
1. Burnt screen.
2. Bad contact in display
connections.
1. Replace the display with a new one.
2.
Check and clean the contacts of the
different jacks of the display.
Emergency
ven
tilation
or technical failure
1. Failure of an electrical
component.
2.
Bad contact of an electronic
component or cable.
3.
Too much dirt inside the
device.
4. Extremely high
electromagnetic interference
(EMI).
1. Check the condition of the electronic
components of the
sensors board,
ancillary board and CPU board.
2. Check soldering of wires and
electronic components.
3.
Clean all the inside of the device,
and clean the jacks.
4.
Check for the presence of electrical
devices nearby.
