disconnect the anesthetic circuit so that the gastric
contents are not forced into the lungs. Check
that anesthetic depth is adequate and deepen
anesthesia intravenously, if appropriate.
• Apply suction through the mask’s patient tube and
through the mouth. Suction the tracheobronchial
tree and inspect the bronchi using a flexible scope.
3.7. Usage with other devices/equipment
ANESTHETIC SYSTEM AND VENTILATION BAG
The mask can be used for either spontaneous or
controlled ventilation.
During anesthesia, nitrous oxide may diffuse
into the cuff causing an increase in cuff volume/
pressure. Adjust cuff pressure just enough to obtain
an adequate seal (cuff pressure should not exceed
60 cmH
2
O).
The anesthetic breathing system must be adequately
supported when connected to AuraOnce to avoid
rotation of the mask.
USAGE WITH SPONTANEOUS VENTILATION
AuraOnce is suitable for spontaneously breathing
patients when used with volatile agents or intravenous
anesthesia on condition that anesthesia is adequate
to match the level of surgical stimulus and the cuff is
not overinflated.
USAGE WITH POSITIVE PRESSURE VENTILATION
When applying positive pressure ventilation, ensure
that the seal is adequate. To improve the seal the
following is suggested:
• Optimize placement of AuraOnce by head turning
or traction.
• Adjust the cuff pressure. Try both lower and higher
pressures (a poor cuff seal may be caused by either
too low or too high cuff pressure).
• If leakage should occur around the cuff, remove the
mask and reinsert while ensuring that anesthetic
depth is adequate.
MAGNETIC RESONANCE IMAGING (MR)
AuraOnce is MR-safe.
3.8. Removal procedure
Removal should always be carried out in an area where
suction equipment and the facility for rapid tracheal
intubation are available.
Do not remove AuraOnce with the cuff fully inflated to
prevent tissue trauma and laryngospasm.
3.9. Disposal
Dispose of used Ambu AuraOnce in a safe manner
according to local procedures.
