TROUBLESHOOTING
Airway contamination
Problem
– Simulator airways have become contaminated from mouth-to-
mouth rescue breathing.
Solution
– Clean the outside of the Patient Simulator with Manikin Wipes.
Clean the inside of the oral cavity with Manikin Wipes. Change
the Lung Bladders; see: Maintenance - Replacing Lung Bladders.
Note: The Patient Simulator airways are not designed for
mouth to mouth rescue breathing or to be disinfected.
Chest movement
Problem
– No chest rise on Patient Simulator.
Solution
– Check that Patient Simulator is switched ON.
– Check that Patient Simulator is not in sleep mode due to
inactivity. Reactivate the Patient Simulator.
– Check that awRR is not set to zero in LLEAP (Patient Case or
scenario)
– Check that airway complications like maximum air resistance or
laryngospasm are not set.
– Check if the internal compressor is switched off. See: Turning the
Internal Compressor Off/On.
– Check that any external compressed air source is switched off
and that the air tube is disconnected from the Patient Simulator.
– The internal compressor may have overheated. Wait
approximately 20 minutes for it to cool down. Remove blankets
or covers from the Patient Simulator, open the Torso Skin to
facilitate cooling.
– Chest-rise is set to bilateral (for example if ET-tube is inserted
too far into the bronchia).
– Chest-rise bladder is leaking or tubing to Chest Rise Bladder is
twisted, kinked or disconnected. Replace Chest Rise Bladder if it
is leaking, see Maintenance: Replacing Chest Rise Bladders.
– Check air tubing for leakage; check that all connections are intact.
Replacing tubing if necessary.
– Shallow chest movements and the internal compressor runs
continuously. The internal compressor may be worn - contact
Laerdal Technical Service.
Simulator Limbs
Problems
– Lack of motion in the legs.
Possible Solution
– Loosen and re-adjust the hip joint nuts on the inside of the
pelvis. See Maintenance for details on how to attach the legs
Lungs
Problem
– Lungs not functioning properly.
Possible Solution
– Check that the airway resistance is not set to maximum in
LLEAP.
– Open the torso and chest plate. Check that the lungs are free to
expand and are not restricted by any cables.
– Check that the lung bladders are properly connected, and that
the tubes are not twisted.
– Check that the lung bladders are in a horizontal position and
inserted correctly. Ensure that the lung compliance O-rings lie
between the folds of the lung bladders.
– Check for flaws or ruptures in the lung bladders.
– Check that the two lung compliance O-rings are fitted correctly.
Replace O-rings if they appear to be damaged.
– Check that there are no obstructions inside the simulator
airways which may block air flow.
– If there is no change when adjusting lung compliance, contact
Laerdal Technical Service.
– If there is no change in lung resistance, contact Laerdal Technical
Service.

Batteries
Problem
– Battery life is less than 150 minutes with healthy patient and fully
charged batteries.
Possible Solutions
– Batteries may be old, (recommended lifetime is 200 discharge
cycles). Insert new batteries.
– Compressor may not function properly; consult your local
Laerdal Technical Services Centre.
Pulses
Problem
– Cannot feel pedal pulses.
Possible Solutions
– Skin may be too tight over pulse units – readjust skin and reboot.
