Airway Adapter Tube

WARNING: Do not reuse the Model 9840AAT Airway Adapter Tube. Cleaning the
interior will damage the anti-fog coating and cause inaccurate readings or a CO
sensor alarm.
WARNING: The Model 9840AAT Airway Adapter Tube will increase dead space by
approximately 6 cubic centimeters (0.4 cubic inches); this may adversely affect
ventilation for animals with small tidal volumes.
CAUTION: Do not use the airway adapter tube if the airway adapter tube is below
!
5 °C (41 °F). An airway adapter tube that is below 5 °C (41 °F) may frost, causing a
false reading. Warm the airway adapter tube to above 5 °C (41 °F) by putting it in a
warm place (for example in your hands or in a vehicle) before use.
CAUTION: An airway adapter tube that is between 5 °C (41 °F) and 10 °C (50 °F)
!
may cause inaccurate readings due to fogging of optical surfaces. It is recommended
that the airway adapter tube be warmed to above 10 °C (50 °F) before use.
The Model 9840AAT Airway Adapter Tube (figure 8) is a single-use only, disposable adapter designed
to be placed between the endotracheal tube and the breathing circuit of intubated animals. The airway
adapter tube connects to the CO
