What should you do if a person becomes unresponsive during a choking episode?

In a situation where a person becomes unresponsive during a choking episode, immediately beginning chest compressions is crucial because it enables you to clear the airway by providing forceful compressions to the chest. This action can help dislodge the object that is causing the obstruction.

When someone is unresponsive, they are unable to cough or breathe, which makes them at high risk for severe complications. Chest compressions not only attempt to expel the obstructing object but also maintain blood flow to vital organs, including the brain, which is critical in preventing further injury.

While options such as encouraging a cough or continuing back blows would be suitable for someone who is still conscious and responsive, they are not effective once a person has lost responsiveness. Leaving to seek help would not provide immediate assistance to the individual in distress, which can be life-threatening in the case of choking. Therefore, performing chest compressions is the most appropriate and potentially life-saving action in this scenario.
