(c) Bag-valve-mask (BVM) or oxygen with demand valve. Check the
BVM each time prior to use, particularly the cuff. Also, check the corneal reflex and the
gag reflex. Check the casualty for the presence of a corneal reflex by touching the
casualty's cornea with your fingers. If the eyelid does not try to close, continue with the
procedure. If the eyelid tries to close (blink), the gag reflex is still present and you
cannot proceed with insertion of the device. Periodically recheck for the reflex, and
when the eyelid does not try to close, continue with the procedure.
Lubricate the EOA or EGTA.
Oxygenate the casualty with two full, slow breaths.
(4) Grasp the casualty's tongue and jaw, lifting both upward and forward
without hyperextending the neck.
Grasp the tube below the mask using the fingers of your other hand.
(6) Insert the EOA or EGTA (without pushing hard) following the curve of
the pharynx until the mask settles on the casualty's face.
(7) Seal the mask and check its placement by blowing into the tube and
watching for the rise of the casualty's. (If the chest does not expand or rise, remove the
tube quickly and reoxygenate.)
You must wait 3 minutes before doing these procedures again.
Inflate the balloon of the EOA or EGTA with no more than
35 ml of air.
