Removal Procedure - Ambu AuraStraight Bedienungsanleitung

• The vertical line on the patient tube should be oriented
anteriorly towards the patient's nose.
• AuraStraight is inserted correctly when the patient's
incisors are between the two horizontal lines on the
patient tube. 2 , item 5. Reposition the mask if the
patient's incisors are outside this range.
• The position of AuraStraight can be assessed by
capnography, by observation of changes in tidal
volume (e.g., a reduction in expired tidal volume), by
auscultating bilateral breath sounds and an absence of
sounds over the epigastrium and/or by observing chest
rise with ventilation. If you suspect that AuraStraight
has been positioned incorrectly, remove and reinsert –
and ensure that anesthetic depth is adequate.
• Visual confirmation of anatomically correct position is
recommended, e.g., by using a flexible scope.
UNEXPECTED REGURGITATION:
• Regurgitation may be caused by inadequate level of
anesthesia. The first signs of regurgitation may be
spontaneous breathing, coughing or breath-holding.
• If regurgitation occurs, if oxygen saturation remains at
acceptable levels, AuraStraight should not be removed.
This should be managed by putting the patient in a
"head-down" position. Briefly 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 cm H O).
2
The anesthetic breathing system must be adequately
supported when connected to AuraStraight to avoid
rotation of the mask.
USAGE WITH SPONTANEOUS VENTILATION
AuraStraight 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 AuraStraight 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)
AuraStraight 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 AuraStraight with the cuff fully inflated to
prevent tissue trauma and laryngospasm.
3.9. Disposal
Dispose of used Ambu AuraStraight in a safe manner
according to local procedures.
