Final answer:
If a choking victim is pregnant or too large, you should perform chest thrusts to dislodge the obstructing object.
Step-by-step explanation:
If a choking victim is pregnant or too large for you to wrap your arms around their waist, you should perform chest thrusts. Chest thrusts involve placing your fist in the middle of the victim’s chest, just above the bottom of the breastbone, and using your other hand to apply pressure to the back between the shoulder blades. This method creates enough force to dislodge the obstructing object without causing harm to the victim or the unborn baby.
