by straddling the victim at the hips. Place the heels of your hands one on top of the other, along the midline, slightly above the navel, and give four quick upward thrusts into the abdomen, as illustrated in figure 4-7. Note that the victim must be lying face up.
Figure 4-7.Position for reclining abdominal thrust.
If unsuccessful, repeat the four abdominal thrusts until the obstruction is dislodged.
For obese or pregnant victims, the chest thrust methods are recommended for removing airway obstructions since manual pressure in the abdomen area of these people would either be ineffective or cause internal damage.
