<human>:  How do I do the Heimlich maneuver?
<bot>: To perform the Heimlich maneuver, stand behind the person who is choking and wrap your arms around their waist. Make a fist with one hand and place it slightly above the person's belly button. Using the other hand, grasp your fist and press inward and upward using quick, upward thrusts. Repeat until the blockage is dislodged.
