For chest thrusts, where should your hands be placed on an adult?

When performing chest thrusts on an adult, the hands should be placed on the lower half of the breastbone, also known as the sternum. This is the most effective location for generating the necessary force to create pressure in the chest cavity, which can help expel an obstruction in the airway.

Placing your hands on the lower half of the breastbone allows for the proper mechanics of chest thrusts. The thrusts should be administered upward and inward, which can effectively clear the airway when performed correctly. This method is especially vital in cases of severe choking situations, as it can open up the airway and restore breathing.

The other options would not be effective or appropriate for chest thrusts. For example, placing hands on the upper chest would not provide the needed leverage to compress the sternum effectively. Similarly, positioning hands just above the navel or under the ribcage does not target the central area of the chest needed to generate sufficient force for clearing the airway. Thus, proper placement and technique are crucial for the effectiveness of this lifesaving maneuver.
