In what position should you place a choking adult who becomes unresponsive?

When dealing with an unresponsive adult who is choking, the appropriate action is to place them on their back on a firm surface. This position allows for the most effective access to perform essential lifesaving interventions such as chest compressions and rescue breathing if necessary. By positioning the person on their back, rescuers can use the proper techniques to clear the airway, whether through back blows or abdominal thrusts, if the choking capability needs to be addressed quickly. Additionally, a firm surface is crucial for effective compressions, which are necessary to restore proper circulation and, ideally, eliminate any obstructions in the airway. This position also facilitates the transition to CPR if the person does not regain responsiveness.
