■ When the analyzer detects an agent
mixture:
• In Auto ID Mode — The mixed
condition is reported by
displaying I MIX and E MIX as the
agent labels on all screens.
• In Manual ID Mode — In large
text screen, the mixed condition
is reported by displaying the word
MIX under the parameter label
area next to the units of measure.
In the small text screen or the
split screen central, the
parameter labels will alternate
between the mix labels in normal
video and the selected agent-
type labels in reverse video.
■ The display zones will continue with
the above displays, until the mix of
the agents has flushed from the
patient and delivery system and a
single agent identity has been
detected.
■ Depending on the agents used, the
residue in the patient, and the
breathing or delivery system, mixed
conditions can last for more than an
hour.
