Analyzer Connections
You can connect the Analyzer to a ventilator and
test lung in either a bi-directional or
unidirectional flow configuration.
Airway Flow (Inlet and Exhaust)
The outer diameter of the airway port is a
standard 22 mm fitting for use with patient
hoses. The inner diameter of the airway port
accepts a 15 mm male respiratory fitting for use
with endotracheal tubes, gas sampling adapters,
and similar equipment.
Caution
W
To avoid damage to the Analyzer and
avoid adverse affects on the Analyzer
performance:
• Do not put metal objects into
connectors.

• Always use the external flow filter on
the main airflow channel inlet. This
helps reduce turbulence and keeps
out small particles that could
damage the flow sensor.
• To avoid damage to the sensor,
make sure the pressure inside the
airway port does not exceed 5 psi.
• Measure only dry gases with the
airway port. Do not use this port to
measure humidified gases.
