The use of any other cleaning agent, especially ammonium chloride, is strongly discouraged as there is a high risk it will shorten the lifespan of
the device and its accessories.
To disinfect the different components, the following cleaning agents can be used:
• 70-90% isopropanol
• Super Sani-Cloth Plus disinfection wipes
• Sodium hypochlorite diluted with water at 1:500 (bleach)
Clean these elements with a soft cloth dampened with hospital grade cleaner that is not corrosive to plastic
or metal. Do not pour or spray any liquids onto the device, and do not allow any liquids to enter any openings
on the device. Do not immerse the cables in liquid and avoid contact between the cleaning agent and the
connectors.
Clean the gold cup electrode cables with alcohol free soap. A toothbrush can be used to scrub the cups to
remove paste and debris. Be careful not to scrub too aggressively to avoid damaging the gold plating.
Wipe the device with a soft cloth dampened with a 10% bleach / 90% water solution (household bleach
[containing less than 10% sodium hypochlorite]). Do not use undiluted bleach or any cleaning agent other than
those recommended here, as permanent damage could result.
Unplug the probe from the pulse oximeter before cleaning. To clean the probe, wipe all patient contact
surfaces with a soft cloth dampened with a mild detergent, isopropyl alcohol, or a 10% bleach / 90% water
solution (household bleach [containing less than 10% sodium hypochlorite]).
Do not sterilise in an autoclave or immerse the sensor in liquid of any kind. Do not pour or spray any liquids
onto the sensor. Do not use caustic or abrasive cleaning agents on the sensor. Do not use cleaning agents
containing ammonium chloride. Use of these chemicals may shorten the life of the product.
