Cleaning and
Disinfecting the
Ventilator Bellows
Manufacturers of rubber goods recommend that reusable rubber goods
be soaked in a liquid disinfection agent. Always follow the agent
manufacturer's instructions for use.
CAUTION: Disinfectants containing phenol or phenyl compounds
destroy rubber goods. Latex and rubber goods treated with
disinfectants having a quaternary ammonium base will be
damaged if subsequently autoclaved.
Use 2% glutaraldehyde-based formulations for more than 20 minutes or
wet pasteurization at 70° C for 30 minutes after detergent cleaning.
Thoroughly rinse the corrugated hoses, mask elbow, and breathing bag
after contact with chemicals. Use sterilized water to prevent
contamination by tap water organisms. Thoroughly dry rubber goods
before returning them to service.
The corrugated hoses, mask elbow, and breathing bag can be autoclaved
at 121° C. However, such temperatures accelerate the natural aging of
rubber goods. Autoclaved rubber goods can also harden over time as a
result of the loss of softeners. Exposure to ozone or ultraviolet light also
accelerates the natural aging of rubber goods. Reusable rubber goods can
also be gas sterilized with ethylene oxide. After EtO sterilization,
properly aerate rubber goods before returning them to service. Always
follow manufacturer's instructions for these procedures.
CAUTION: Do not autoclave face masks. Autoclaving causes rapid
deterioration of face mask cushions.
The Y-piece and mask can be disinfected by wiping or immersion with
glutaraldehyde-based formulations. EtO and wet pasteurization
processes can also be used.
The ventilator bellows and its bottom assembly are the only ventilator
components that come in contact with the patient's breath. Refer back to
"Cleaning and Disinfecting Exterior Surfaces" for instructions on
cleaning and disinfecting the surface of the ventilator bellows assembly.
Clean the bellows with a soft lint-free cloth moistened with mild alkali
detergent and water, followed by a distilled water rinse. Let the bellows
drip dry.
After cleaning, use wet pasteurization at 70°C for 30 minutes, a
gluteraldehyde-based solution, or an EtO process to disinfect the
ventilator bellows. Follow manufacturer's guidelines for these
procedures.
