a. Head-Tilt/Chin-Lift Method. The head-tilt/chin-lift (figure 3-2) is the
preferred method of opening the casualty's airway if a neck fracture is not suspected. In
addition, loose dentures can be handled easier using the head-tilt/chin-lift method.
Figure 3-2. Opening the airway: head-tilt/chin-lift method.
Kneel at the side of the casualty's head or shoulders.
Place your hand (the hand closest to the casualty's head) on his
(3) Apply firm, backward pressure with the palm of your hand. This
pressure will cause the casualty's head to tilt back.
(4) Place the fingertips of your other hand under the bony part of his chin,
not on the soft flesh under his chin. Pressing on the soft flesh under the chin could
result in blocking his airway.
(5) Lift his chin with your fingertips. Continue to lift the lower jaw until his
upper and lower teeth are almost brought together. The mouth should not be closed as
this could prevent air from entering the casualty's airway.
b. Jaw-thrust Method. The jaw-thrust (figure 3-3) is the preferred method of
establishing an airway if you suspect that the casualty has a fractured neck. The jaw-
thrust method moves the casualty's tongue forward (away from the airway) without
extending his neck.
