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.

Important Information
This User Guide covers two configurations of the LSU: Reusable and Serres Suction Bag
System. Unless otherwise specified, the information in this User Guide applies to both
configurations.
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.
• The LSU Reusable must not be used without the Aerosol Filter or the Float Ball.
• 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.
6
Battery
Cautions
• Only use batteries approved by Laerdal Medical. Other batteries will have problems related
to the battery status indicator of the LSU, the batter y 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).

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 Device Test.
LSU Reusable:
• Check that the Patient Suction Tubing is securely connected to the Patient Inlet on the
Canister Lid; and the Aerosol Filter is securely fastened in the LSU and the lid.
• Check that a suction catheter is attached to the patient suction tube or suction
adapter. Do not use the suction tube or suction adapter without a suction catheter
attached.
LSU Serres:
• 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).
Use
1. Unwind the Suction Tubing. Set the Operating Knob to the required vacuum level.
The LSU will switch on and start to operate. The Power On Indicator lights up
during operating.
2. When suction is complete, set the Operating Knob to “0” to turn off.
