English
5
Intended Use
The LCSU 4 is a portable, electrically powered, medical suction device 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 suction, and lower vacuum levels are usually selected for tracheal suctioning and the suctioning
of children and infants.
Important
• Do not use this unit until you have carefully read and fully understood these Directions for Use. Contact Laerdal Medical or its
authorized distributor for additional information if required.
• Federal law (USA) restricts the LCSU 4 to sale by or on the order of a physician or other licensed medical authority.
• Use only Laerdal accessories supplied directly by Laerdal Medical or one of its authorized distributors to ensure that the LCSU
4 operates satisfactorily.
Cautions and Warnings
Cautions
• The LCSU 4 is not suitable for use in the presence of flammable liquids or gases; danger of explosion or fire.
• Do not use the LCSU 4 under environmental conditions that are outside ranges specified. This can endanger safety and
adversely affect device operation.
• Ingress of suctioned material into the pump can damage and/or disable the device. If suctioning of liquid from the Canister or
patient into the pump is suspected, do not use the LCSU 4. Contact Laerdal Medical or your authorized distributor for advice.
Warnings
• The LCSU 4 should only be used by persons trained in the use of medical suction equipment, and according to local protocol.
• Unauthorized service attempts, opening or tampering with the LCSU 4 or its electrical components can damage or disable the
device, and will void the Limited Warranty.

Important
The 800 ml Canister has an internal Filter in the Lid. The Canister is disposable and cannot be cleaned. The Filter
automatically stops suction/flow when the Canister is full, or the Filter becomes saturated if the unit tips onto its side during
use.
Caution
Always use the 800 ml Canister supplied by Laerdal, which has an internal Filter. Never connect any type of Patient Tubing
directly to the LCSU 4 Vacuum Inlet Port Connection. Overflow of suctioned material into the LCSU 4 pump will result in
loss of suction and permanent damage to the unit. In the event of overflow, do not use the LCSU 4. Contact Laerdal Medical
or your authorized distributor.

Important
• The 300 ml Canister is sealed, with an internal Filter. The
Canister is disposable and cannot be cleaned. The Filter
automatically stops suction/flow when the Canister is full,
or the Filter becomes saturated if the unit tips onto its side
during use.
• The 300 ml Canister (Cat. No. 886100) can also be used with
the previous model LCSU 3. However, the LCSU 4 cannot
be used with LCSU 3 Canisters.
• To improve the upright stability, a Wire Stand (Cat. No
886115) is offered as an Optional Accessory. This adds
both a handle and a foot to the unit.
Caution
Do not attempt to install or use LCSU 3 Canisters on
LCSU 4.
Check Before Each Use
1 The Unit should not be damaged.
2 The Unit should be clean.
3 All parts should be properly assembled (Canister, Tubes etc.).
4 Perform Device Test after each reassembly (see Chapter 6).
5 Check Battery level: While performing the Device Test the
Battery level should not illuminate RED. If the Battery
level illuminates RED, the Battery should be charged. See
Charging Instructions (Chapter 5).
Important
For both models - always have an extra Canister available
in case the first Canister is filled completely, or the unit
becomes tipped on to its side and the Filter becomes
saturated and stops the suction/flow.
Warning
If the Canister on either model fills and the shut-off
mechanism activates, and you have no spare Canister
ready for immediate replacement, shut off LCSU 4 and
utilize alternative methods according to local protocol
to clear patient’s airway. Continued efforts to suction
with LCSU 4 Canister(s) filled may cause overflow that
will prevent suctioning, damage the pump, void the unit
warranty, and lead to prolonged downtime.
