K. Check for water accumulation in
the breathing and scavenger hoses,
and in the absorber dust cup.
Remove any water found.
Check the status of the absorbent
in the absorber system: Ensure an
adequate supply of CO
in the absorber system. Consult the
absorbent manufacturer's literature
and replace the absorbent when
signs of exhausted absorbent are
evident. Make sure that the color
change represents the absorbent's
true state of depletion and is not
due to regeneration after a rest
period.
Remove
accumulated
dust and water from the absorber
dust cup. Absorbent is caustic and
is a strong irritant to the eyes, skin,
and
respiratory
emptying the absorber dust cup,
take care not to spill its caustic
contents.
Check for free gas passage in the
patient breathing system: With a
surgical mask over your mouth,
inhale and exhale through the
breathing
system
individually if possible). Verify the
unidirectional flow in each limb and
then reconnect the tubing.
Perform a breathing and fresh gas
delivery system pressure test. This
test detects leaks from the patient
breathing system and fresh gas
delivery system.
