2. Join the tabs on one side of the airway adapter tube onto either side of the CO
2
sensor
(figure 9-A), then rotate the airway adapter tube (figure 9-B) and push firmly to set the other
pair of tabs. You should hear a clicking sound as the pieces are connected together
(figure 9-C).

Sensor
3. Ensure the airway adapter tube and the CO
2
sensor are firmly attached to each other. Gently
tug on the assembly to make sure the pieces are tightly connected.
NOTE: Both sides of the airway adapter tube must be connected onto the CO
2
sensor. If only
one side of the airway adapter tube is attached to the CO
2
sensor, the pieces will come apart and
will cause a CO
2
sensor alarm.
The airway adapter tube attaches between the endotracheal tube of the animal and the breathing
circuit. See Figure 10 for an illustration of the configuration.
NOTE: Not all tapered connectors are compatible with the airway adapter tube. Ensure all
connections are secure.
