Dust Cup
Clean the sensor after each working day by running distilled water
through the housing.
CAUTION: The respiratory volume sensor cannot withstand
immersion or the heat and pressure of autoclaving.
After cleaning, dry the sensor with a hose-drying unit or allow it to dry
overnight.
The respiratory volume sensor can withstand EtO processes. Use
ethylene oxide gas at a temperature not exceeding 50°C. Follow the
manufacturer's guidelines for proper aeration.
Wipe the pressure gauge assembly with a soft lint-free cloth moistened
with mild detergent and water. Dry the assembly before reinstalling.
The gauge can be disinfected with ethylene oxide gas, followed by
appropriate aeration. Follow the manufacturer's instructions.
CAUTION: The breathing system pressure gauge cannot withstand
immersion or the heat and pressure of autoclaving.
Refer to the instructions provided earlier in this chapter under the
heading, "Replacing the Absorbent" for instructions on removing the
absorbent canister assemblies from the absorber.
Clean the canisters frequently. Remove used absorbent and clean
absorbent residues for the canister and gasket surfaces. Check the dust
cup periodically. Empty and clean it when necessary.
WARNING: Absorbent is caustic. Avoid contact with the skin and eyes.
After removing the canister assemblies and dust cup from the absorber
system, wash these parts with mild alkali detergent and water. The
canister assemblies and dust cup can be immersed or wiped with a soft
lint-free cloth. Allow the parts to dry.
Several methods can be used for disinfection. Wet pasteurization,
autoclaving, EtO, and immersion or wiping with 2% glutaraldehyde-
based solution are all acceptable. If an EtO process is used, make sure
the parts are properly aerated before returning them to service.
