Some AVEA Features

Artificial Airway Compensation

When Artificial Airway Compensation is turned on, the ventilator automatically calculates the pressure drop across the
endotracheal tube. The AVEA then 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
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.
WARNING!
Activating 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. If you choose to activate Artificial Airway
Compensation while the patient is attached to the ventilator you will need to exercise caution to minimize the
risk of excessive tidal volume delivery.
Note:
Monitored airway pressures (inspiratory) will be higher than set values when Artificial Airway Compensation is active.
With an inspiratory pressure setting of zero, Artificial Airway Compensation will still provide an elevated airway pressure,
which will compensate for the resistance of the endotracheal tube.
When turned on the Artificial Airway Compensation indicator will appear in all modes of ventilation even though the
function may not be active (i.e.: Volume Controlled Breaths). This is to alert you to the fact that Artificial Airway
Compensation will become active if a Pressure Support or combination mode (e.g. Volume Control SIMV) is selected.
