What is the best way to relieve choking in adult?

The best way to relieve choking in an adult is to perform the Heimlich maneuver. Here are the steps to do it:

1. Ensure the person is choking. If the person is able to speak or breathe, they may not be choking.

2. Stand behind the person and support their upper body by putting one arm around their waist.

3. Place your other hand on their abdomen, just below their rib cage.

4. Give a quick, upward thrust with your hand. Use enough force to dislodge the obstruction, but not too much force as to cause injury.

5. Repeat the thrusts until the obstruction is cleared or the person begins to breathe.

6. If the person becomes unconscious, lay them on their back and begin CPR.
