Cleaning and Disinfecting
CAUTION! Before cleaning Absorber Canister, remove all loose debris and dust. Applying water to
carbon dioxide absorbent causes it to harden, making it difficult to remove.
Patient circuits, hoses, and breathing bags
Clean with dilute chlorhexidine type solution: 1 ounce (2 Tablespoons) per gallon of water. Hang circuits up to
dry. Inspect circuits for any noticeable deterioration.
Machine surfaces
Clean with dilute chlorhexidine type solution: 1 ounce (2 Tablespoons) per gallon of water.
Absorber Canister
To remove the absorber canister, loosen the draw knob at the top of the aluminum block directly above the
canister. After removing the canister, dispose of all particles and dust. Clean with mild soap and water and dry
completely. Inspect for damage and replace if necessary. Wipe the gasket underneath the block with Isopropyl
alcohol and dry completely before reassembly. Do not saturate gasket.
Inhalation/Exhalation Valves
Unscrew the plastic dome caps that rest on top of the inhalation/exhalation valves. Visually inspect the dome
caps for cracks or worn areas that may leak. Visually inspect the plastic flutter disks for tears, signs of wear, or
curling. Ensure the disk completely covers the valve opening. Visually inspect the gaskets for signs of wear or
curling. Clean all components with mild soap and water, dry completely. Replacement dome caps, flutter disks,
and gaskets are available.
