6.1 Install the Absorber Canister
WARNING: Follow the proper security measures:
• Do not use the absorber if the anesthetic is chloroform or
trichloroethylene.
• The materials in the absorber are dangerous; avoid contact with the
skin or eyes. If contact occurs, clean the affected area immediately
and seek medical attention. Do not replace absorber during
ventilation.
• Do not replace the absorber if the Breathing System is in operation.
• Replace the absorbent often to prevent the deposits of non-metabolic
gas when the system is turned off.
• Check the color of the absorbent after each use. The original color of
the absorbent may be restored when not in use. Refer to the labels on
the absorbent for additional details.
• Carbon monoxide is released if completely dried absorbent comes
into contact with the anesthetic. Replace the absorbent for security.
• Perform leakage testing of the breathing system in manual mode after
installing the absorber.
The absorber in this system can be used repeatedly.
The capacity of each absorber canister is 1500 ml.
Only Air, Oxygen, Nitrous Oxide, Halothane, Enflurane, Isoflurane, Sevoflurane and Desflurane are
used for the absorber.
6.1.1 When to Replace Absorbent
Change in color of the soda lime in the absorbent indicates that it has absorbed carbon dioxide;
however, this color is not 100% accurate. To decide whether to replace the absorbent, use the CO
2
monitoring machine.
Immediately remove absorbent that has changed color. Soda lime sometimes reverts to its original
color several hours after use.
