What actions should you take if you encounter someone who is choking?

When encountering someone who is choking, performing a combination of back blows and abdominal thrusts is the appropriate course of action. This technique is effective in creating sufficient pressure to dislodge an object obstructing the airway. The back blows can help to dislodge the obstruction by using the force of gravity and the momentum of the strikes, while the abdominal thrusts create a burst of air pressure from the lungs, increasing the chances of removing the blockage.

This dual approach is crucial because it addresses the choking incident from different angles, maximizing the likelihood of success. It's essential to act promptly in these situations, as choking can quickly lead to serious consequences if not resolved. Promptly assisting the individual who is choking with both methods ensures that various mechanisms are at play to help clear their airway effectively.
