Intended Use
The Laerdal Suction Unit (LSU) is a portable, electrically powered, medical suction
equipment intended for field and transport use. It is intended for intermittent operation
to remove secretions, blood or vomit from a patient´s airway to allow ventilation.
Higher vacuum levels are generally selected for oropharyngeal suctioning, and lower
vacuum levels are usually selected for tracheal suctioning and the suctioning of children
and infants.
Read this User Guide carefully, and become thoroughly familiar with the operation and
maintenance of the LSU before using it. Read all Cautions and Warnings before using
the LSU.
Warnings and Cautions
A Warning states a condition, hazard, or unsafe practice that can result in serious personal
injury or death.
A Caution states a condition, hazard, or unsafe practice that can result in minor personal
injury or damage to the product.
Warnings
• The LSU is not suitable for use in the presence of flammable liquids or gases; there can be
a danger of explosion or fire.
• Not intended for use in MRI environments.
• Do not use the LSU under environmental conditions that are outside the ranges specified in
Specifications section.This can endanger safety and adversely affect operation of the device.
• Do not block the Exhaust Outlet during use. This will lead to reduced flow and can also
cause damage to the LSU.
• Disconnect the LSU from external power prior to cleaning. Use a minimum amount of liquid
to prevent any electrical shock hazard.
• Do not immerse the LSU or allow it to stand in water or other liquids.This might damage
the device, and cause electrical hazard.
Cautions
• Do not pump any cleaning solution or other liquids through the vacuum pump, i.e. through
the Vacuum Connector.This can damage the LSU.
• Use only parts and accessories supplied by Laerdal Medical or one of our authorised
distributors to ensure that the LSU operates satisfactorily.
• Overflow of suctioned material can damage the device. If overflow of liquid from the
Canister into the pump is suspected, contact your local Laerdal Medical representative.
• The LSU should only be used by persons trained in the use of medical suction equipment.

Important Information

Battery
Cautions
• Only use batteries approved by Laerdal Medical. Other batteries will have problems related
to the battery status indicator of the LSU, the battery operation time and safety.
• The LSU must be charged between each clinical use.
• To maintain satisfactory operation of the battery, placing the LSU on continuous charge
immediately after use and when not in use is recommended.
• If it is not possible to place the LSU on continuous charge when not in use, make sure the
battery is charged for a minimum of 4 hours at least once a month.
• The LSU must be placed on charge for a minimum of 4 hours to reach full battery capacity.
Fast charging gives approximately 80% battery capacity after 3 hours (for a new battery).
Repetitive 3 hour charging is not recommended.
• Fully charging the battery is recommended. Repetitive charging to a lower capacity level will
reduce battery life.
• Always fully charge the battery before storage.
• Do not store the battery when it is discharged.
• Do not store the LSU with a discharged battery.
• Laerdal recommends charging a spare battery every 6 months when stored in room
temperature at 25 °C (77 °F).

Note
Turn the operating knob to 500+ mmHg. Block the Patient Inlet with your thumb and
simultaneously push the lid down.The lid is properly installed when vacuum has reached
500 mmHg. Release the Patient Inlet and make sure that the bag is fully inflated.

Before Use Checklist
• Check that no parts are missing and that all parts are clean.
• To operate the LSU from an external power source, connect to either external AC or
DC power. To operate the LSU from the internal battery, check that the
battery is installed.
• Run DeviceTest.
• Check that the Serres Vacuum Connector is properly connected to the LSU and to
the canister.
• Check that the lid of the canister is properly sealed: block patient inlet and turn on the
LSU.Vacuum will build up when all parts are assembled correctly.
• Attach appropriate suction catheter if necessary. (Not supplied by Laerdal Medical).

Caution
Even if the Operating Knob is set to “0”, voltage is present on some of the internal circuitry
when the LSU is connected to external power. Disconnect from the mains to fully remove
power.
Note
The LSU has an automatic power save mode which switches the pump motor off. While in
this mode, the Power On Indicator will flash slowly (approx. once per second). Power save
mode is activated when the Operating Knob is set to 200, 350 or 500+ mmHg and the
actual vacuum level has been continuously higher than 120 mmHg for more than 2 minutes.
To exit power save mode and revert to normal operation, set the Operating Knob to any other
position and then go back to required setting.
After Use Checklist
• Inspect all parts of the LSU for damage and excessive wear. Replace parts if necessary.
• Clean the LSU cabinet. Clean and disinfect reusable parts. See Cleaning section.
• LSU Serres:The Serres Vacuum Connector should be replaced regularly. Place an
unopened Serres SuctionTube on the side of the LSU.
• Perform Device Test. See Device Test section.
• Place the LSU on charge.
Note
The Serres Suction Bag system contains a hydrophilic filter that shuts off the vacuum if the
canister is full or the LSU tips over. To restore the vacuum, replace the Suction bag.
