If you are choking on something, you can perform the Heimlich maneuver on yourself:

1. Make a fist. Place the thumb below your rib cage and above your navel.
2. Grasp your fist with your other hand. Press it into the area with a quick upward movement.

You can also lean over a table edge, chair, or railing. Quickly thrust your upper belly area (upper abdomen) against the edge.

If you need to, you should repeat this motion until the object blocking the airway comes out.
