When the back blows are unsuccessful, use the abdominal thrust. This procedure pushes air from the lungs and forces the object from the air passage.

ABDOMINAL THRUST STANDING TECHNIQUE

1. Stand behind the victim and wrap your arms around the victim's waist, as shown in figure 10-5.

2. Make a fist with one hand and place it thumb side against the abdomen, slightly above the navel.

3. Grasp the fist with the other hand (fig. 10-6).

4. Give four quick upward thrusts to the victim.

The obstruction should pop out like a champagne cork.

Figure 10-6.-Correct hand positioning.

ABDOMINAL THRUST RECLINING TECHNIQUE

This technique is performed with the victim lying flat, faceup.

1. Position yourself for the thrust by straddling the victim at the hips.

2. Place the heel of one hand on top of the other, slightly above the navel, with the fingers pointing toward the head.

3. Give four quick upward thrusts to the abdomen.

Following the cycle of 6 to 10 abdominal thrusts, turn the victim's head to one side, and check for loose foreign matter with a sweeping movement of the index finger inside the mouth, then ventilate. Repeat cycles of 6 to 10 abdominal thrusts, finger sweeps, and ventilation until the obstruction is dislodged or until a rescue team arrives.
