91518 Multigas Analyzer Service Manual
5-6
LOW VALUES
OBSERVED
■
A leak exists at the sampling
line connection, a water trap
is broken at the luer
connection, or a gas analyzer
filter is leaking.
■
Check connections and check
for a broken water trap. Perform
leak test. Verify the anesthesia
delivery devices and vaporizer
calibrations. Refer to the
manufacturer’s guides.
AGENT MIX
DETECTED
■
Agent mixture detected.
■
The analyzer is not designed to
simultaneously measure more
than two anesthetic agents.
Inaccurate numeric
concentration values may be
displayed when two or more
agents are mixed. The displayed
value of the mixed condition is
based on the combined value of
agents using the coefficient
factors of the last detected or
selected agent type. Depending
on the agents used, the residue
in the patient, and the breathing
or delivery system, a mixed
agent condition can last for more
than an hour. If the message
persists, contact your biomed or
a qualified field service engineer.
