How to clean the LCSU 4

During the COVID-19 outbreak the World Health Organisation (WHO) has released the following information about environmental cleaning:

Environmental cleaning in healthcare facilities or homes housing patients with suspected or confirmed 2019-nCoV infection should use disinfectants that are active against enveloped viruses, such as 2019-nCoV and other coronaviruses. There are many disinfectants, including commonly used hospital disinfectants, that are active against enveloped viruses. Currently WHO recommendations include the use of:

70% Ethyl alcohol to disinfect reusable dedicated equipment (e.g., thermometers) between uses.
Sodium hypochlorite at 0.5% (equivalent 5000ppm) for disinfection of frequently touched surfaces in homes or healthcare facilities

More information can be found here:

The User Guide for Laerdal Compact Suction Unit 4 (LCSU 4) contains the following Information about cleaning:

Clean Cabinet surfaces by carefully wiping with a soft cloth or sponge with mild detergent. Use hand dishwashing liquid or similar that is compatible with the Material Chart (see Chapter 9 in the user guide). Dry all surfaces using a clean cloth or paper towel.

In light of the current WHO recommendations, Laerdal has reviewed its recommendations for cleaning. Laerdal has not tested the LCSU 4 using 70% Ethyl alcohol or Sodium hypochlorite at 0.5%. Information published by other reliable sources on the cleaning of the materials listed in the table below has been used to provide this guidance.

Resucitador de Silicona Laerdal (LSR) y The Bag

El reanimador de silicona Laerdal (LSR) y el BAG II NO se suministran con un filtro.
Recomendamos que utilice un filtro HMEF entre la válvula del paciente y la máscara, el ET o el tubo supraglótico. Este es un filtro estándar que está ampliamente disponible. Un filtro con un conector de 22F / 15M se ajustará tanto al Resucitador de Silicona Laerdal como a The BAG II. Actualmente, Laerdal no suministra este tipo de filtro.
