The anesthetic breathing system must be adequately
supported when connected to Aura-i to avoid rotation
of the mask.
USAGE WITH SPONTANEOUS VENTILATION
Aura-i 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 Aura-i 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.
INTUBATION THROUGH AURA-I
See Table 1 for selection of appropriate ET-tube size.
Always check the compatibility between the ET-tube and
Aura-i before the procedure. Apply lubricant to the ET-tube
and verify that it moves freely inside the patient tube of
Aura-i.
INTUBATION INSTRUCTIONS
Direct flexible scope assisted endotracheal intubation
can be performed through Aura-i, using a well-lubricated,
fully deflated ET-tube. Integrated navigation marks
provide guidance as to how far the flexible scope has been
introduced. The first mark, Figure
2
item 8a, indicates
that the scope tip should be flexed to visualize the tracheal
opening. The second mark, Figure
2
item 8b, indicates
that the flexible scope has been introduced too far.
Ambu Aura-i may be removed, taking care not to dislodge
the ET-tube.
Do not remove the connector on Aura-i.
DIFFERENT TYPES OF ET-TUBES FOR PEDIATRIC PATIENTS
Aura-i is compatible with both cuffed and un-cuffed
ET-tubes for intubation.
For Aura-i pediatric sizes, it is important to note that if
removal of Aura-i is planned after an ET-tube is placed
through the mask, an ET-tube without cuff must be used.
Intubation through Aura-i should always be performed in
accordance with local guidelines.
Depending on the type of flexible scope used for pediatric
patients, it may not be possible to flex the tip of the scope
right at the first navigation mark. Instead, the tip may be
flexed once the letter “u” of “use” has been visualized.
MAGNETIC RESONANCE IMAGING (MR)
Aura-i 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 Aura-i with the cuff fully inflated to prevent
tissue trauma and laryngospasm.
3.9. Disposal
Dispose of used Ambu Aura-i in a safe manner according to
local procedures.
4.0. Specifications
Ambu Aura-i is in conformity with ISO 11712 Anaesthetic
and respiratory equipment – Supralaryngeal airways
and connectors.
