Remove the syringe to allow self-sealing or clamp the cuff tube, if
necessary.
(10) Auscultate to check placement of the EOA or EGTA by listening with a
stethoscope to the two lower lung fields and the paraumbilical area. You should not
hear a sound like rushing water.
(11) Ventilate once every 5 seconds using a bag-valve-mask (BMV) or a
demand valve and oxygen.
NOTE:
At any point during the procedure, the casualty should NOT be without
oxygen for more than 30 seconds
2-6.
EXTBATING WITH AN EOA AND EGTA
CAUTION:
The EOA or EGTA is not normally removed until the casualty is in the
hospital unless the casualty begins to breathe on his own.
Follow these steps to extubate (remove) an EOA or an EGTA:
a. Oxygenate the casualty with two slow breaths. You can do this by blowing
two slow breaths into the tube, or you can attach an ambu bag and squeeze it two
times. What you are doing is giving the casualty a little too much oxygen to
compensate for the time when he will not be getting quite enough oxygen--the time you
are removing the EOA or the EGTA.
b. Pop off the face mask.
c. Turn the patient to one side.
d. Deflate the balloon cuff with the syringe.
e. Remove the tube following the curve of the pharynx.
f. Clear the airway of vomitus immediately.
