Automatic agent identification
Airway modules with agent identification automatically identify
Halothane, Enflurane, Isoflurane, Sevoflurane, and Desflurane. The
inspiratory and expiratory concentrations of the agent appear in the
digit field or the agent waveform field if selected.
CARESCAPE modules identify two agents simultaneously and
display them as primary and secondary agents. Airway Gas Option
modules identify and display only one primary agent.
Minimum concentration for the identification is 0.15% volume. The
agent selection remains active even if the concentration decreases
below 0.15% volume during the case.
Automatic agent identification operates after the normal warm up of
the gas module (approximately five minutes).
