Clean the ventilator bellows bottom assembly with a soft lint-free cloth
moistened with mild detergent and water, followed by a distilled water
rinse. Allow the assembly to drip dry.
After cleaning, use an EtO process for disinfection. Follow
manufacturer's guidelines.
Wipe the oxygen sensor capsule with a soft lint-free cloth moistened
with mild detergent and water. Make sure the capsule is dry before
replacing it.
CAUTION: Do not immerse or autoclave the oxygen sensor capsule.
After cleaning the capsule, perform an EtO process at a temperature not
exceeding 50°C. Aerate the sensor according to the manufacturer's
instructions.
The oxygen sensor housing can be immersed for cleaning and
disinfection. Use mild detergent and water for cleaning. For disinfection,
follow up with either sodium hypochlorite (5.2% household bleach) l:500
dilution (100 ppm free chlorine) or 70% to 90% ethyl or isopropyl alcohol.
The oxygen sensor housing cover can be immersed or wiped during
cleaning and disinfection. Use mild detergent and water for cleaning.
For disinfection, follow up with a 2% glutaraldehyde-based formulation,
wet pasteurization at 70°C for 30 minutes, or an EtO process.
The inspiratory and expiratory valves come into contact with the
patient's breath. Clean these parts with soft lint-free cloth moistened
with mild alkali detergent and water. Dry the parts before reassembling.
The valve assemblies can be immersed in a 2% glutaraldehyde-based
solution, wet pasteurized, gas sterilized, or autoclaved at a temperature
not exceeding 121° C. The valve disks can also be autoclaved in certain
instances, but should not be autoclaved routinely.
Be careful while handling the valve disks. Improper handling can
damage them. After cleaning or disinfecting the inspiratory or expiratory
valve assembly, verify that the valve disk and all internal pins are
undamaged and that the valve disks are correctly reinstalled.
