In the Setup screen, controls are available to set the following:
Artificial Airway Compensation (AAC)
Range ON/OFF
Default: OFF
When Artificial Airway Compensation is turned on, the ventilator automatically calculates the pressure drop across the
endotracheal tube and adjusts the airway pressure to deliver the set inspiratory pressure to the distal (carina) end of the
endotracheal tube. This calculation takes into account flow, gas composition (Heliox or Nitrogen/Oxygen), Fraction of
Inspired Oxygen (F
IO
2
), tube diameter, length, and pharyngeal curvature based on patient size (Neonatal, Pediatric,
Adult). This compensation only occurs during inspiration. Artificial Airway Compensation is active in all Pressure
Support and Flow Cycled Pressure Control Breaths.
Note:
Monitored airway pressures (inspiratory) will be higher than set values when Artificial Airway Compensation is active.
WARNING
Activation of Artificial Airway Compensation while ventilating a patient will cause a sudden increase in the
peak airway pressures and a resultant increase in tidal volume. Exercise caution when activating Artificial
Airway Compensation while the patient is attached to the ventilator to minimize the risk of excessive tidal
volume delivery.
