6 Cleaning
WARNING:
Never use cleaners inside of the gas pathways. Always follow cleaning instructions indicated in
Section 6, Cleaning.
WARNING:
A patient treated by mechanical ventilation is highly vulnerable to the risks of infection. Dirty or
contaminated equipment is a potential source of infection. Clean the V4C-O2E Oxygen Mixer
and its accessories regularly and systematically before and after each use and following any
maintenance procedure to reduce the risks of infection. The use of a bacterial filter at the
ventilator's outlet is required when using the Oxygen Mixer. To reduce the risk of infection, wash
your hands thoroughly before and after handling the Oxygen Mixer.
WARNING:
Use all cleaning solutions and products with caution. Read and follow the instructions associated
with the cleaning solutions you use to clean your Oxygen Mixer. Use only those solutions listed
in Table 6-1.
WARNING:
The Oxygen Mixer should never be immersed in any liquid, and any liquid on the surface of the
device should be wiped away immediately. To avoid damage to the Oxygen Mixer, in particular
the electrical components, fluids must not be allowed to enter the device, particularly through
the Oxygen Mixer's air intake filter or the cooling/venting apertures located on the rear and
bottom panels of the Oxygen Mixer.
Clean all external panels and surfaces before and after each patient use and as often as neces-
sary to keep the V4C-O2E Oxygen Mixer clean. You should clean the ventilator and Oxygen
Mixer periodically, whenever it is soiled or dirty, before any maintenance operation, and before
storing the device.
To clean the surface of the V4C-O2E Oxygen Mixer:
1. Dip a clean, soft cloth into a mixture of mild soap and water, or other approved cleaning solution.
Refer to Table 6-1 for a list of approved cleaning solutions.
2. Squeeze the cloth thoroughly to remove excess liquid.
3. Lightly wipe the external casing of the V4C-O2E Oxygen Mixer, taking care not to allow excess mois-
ture to enter any of the openings on the V4C-O2E Oxygen Mixer's surface or the Oxygen Mixer air
intake filter.
