As an alternate test, press the oxygen flush button with the Bain
circuit’s patient port open to the atmosphere. The high flow of gas
through the Bain circuit’s inner tube will draw in gas from the
outer tube. As a result, the breathing bag should deflate. If the
breathing bag does not deflate or it inflates, the fresh gas hose or
inner tube may be improperly connected.
Absorber System
Verification
*20. To check the absorber system:
A. Check the hose connections in the breathing system.
B. Make sure the fresh gas hose of the breathing system is
securely connected to the fresh gas outlet.
C. Make sure a 22 mm patient breathing circuit is connected
between the inspiratory and expiratory valves on the
absorber.
D. Make sure a 22 mm breathing hose is connected between
the ventilator hose terminal and the manual/automatic
selector valve breathing hose terminal.
E. Make sure a breathing bag of proper capacity and
appropriate construction is connected to the breathing bag
terminal of the breathing system.
F. Make sure the breathing pressure pilot line is properly
connected between the BREATHING PRESSURE interface
and either the absorber quick-connect fitting or the
appropriate fitting at or near the patient Y-piece.
G. Make sure the oxygen sensor and respiratory volume
sensor are properly installed.
*21. Make sure the absorber canisters are filled with CO

absorbent.
Consult the absorbent manufacturer’s literature for information
on what signs to expect when the absorbent is exhausted. Replace
the absorbent when it appears exhausted. Make sure that the
color change represents the absorbent’s true state of depletion
and is not due to regeneration after a rest period. Flushing the
anesthesia machine continuously with 100% oxygen for at least
one minute before the first case of the day is recommended.
Remove accumulated absorbent dust and water from the absorber
dust cup.
