The cleaning-disinfection-sterilization process
The following steps are generally recommended. Select proper methods for the resuscitator parts in
question according to the table.
Cleaning methods
• Disassemble the resuscitator following the assembly view and order. Do not disassemble the pres-
sure relief valve spring, just rinse it directly.
• Wash the components thoroughly by a soft brush in warm clean tap water containing a mild detergent
(Follow manufacturer's instruction for concentration and exposure time). Ensure that the detergent
is suitable for the component materials to avoid causing damage. See the material specifications at
the end of the instructions. After washing, rinse the parts thoroughly in clean water to remove any
residues of detergent.
• An automatic washing machine with a programme designed for washing anaesthesia accessories
can be used according to the manufacturer's instructions.
Disinfection methods
• Washing machines-heat disinfecting program: Automatic washing machines designed for medical
accessories usually also offer cycles for disinfection by heating, which you can use for the resusci-
tator set.
• Boiling: Immerse the parts in clean tap water, heat to boiling and keep for eg. 10 minutes for disinfec-
tion.
• Aldehyde or other chemical liquid (Ex.: Cidex, chemical with sodium hypochloride,..etc.): Can be used
on all parts of the resuscitator.
• Follow the instructions of the manufacturer of the chemical disinfectant for dilution and exposure
time.
After exposing the resuscitator parts to the chemical disinfectant. rinse all parts of the resuscitator set
thoroughly in clean water to remove the residues.
Notes
• Numerous brands of detergents and chemical disinfectants are available. Use only brands that are
compatible with the resuscitator materials to avoid reduction in the lifetime of the materials. See list
of materials. Follow the instructions of the manufacturer of the detergent or chemical disinfectant for
dilution and exposure time.
• Substances containing phenol should be avoided. Phenol will cause premature wear and degradation
of the materials or reduce the time use of the product.
• Promptly remove all residue of cleaning materials from the resuscitator. Residues may cause prema-
ture wear or reduce the time use of the product.
• Because it is very difficult to thoroughly rinse it afterwards it is not recommended to immerse the
oxygen reservoir in chemical disinfectants.
Sterilization methods
Note for sterilizing timing: When first use of the new resuscitator and when user changed do
sterilization for the resuscitator. Also when the resuscitator was used for more than 48 hours
do sterilization for the resuscitator.
• Autoclaved sterilization max (134°C): Can be used on all parts of the resuscitator, except PVC mate-
rial products. Follow the recommendations given by the steam autoclaving manufacturer. All steam
autoclave cycles used for porous items are acceptable provided that the maximum temperature does
not exceed 273°F or 134°C. If plastic housing made by polycarbonate the maximum temperature
does not exceed 121°C (244°F).
• Ethylene oxide sterilization: Can be used on all parts of the resuscitator. Follow ethylene oxide cham-
ber manufacturer's instruction.
• Gamma radiation sterilization: Can be used on all parts of the resuscitator. Follow gamma radiation
sterilization manufacturer's instruction..
