Which device can be used to assist a choking adult?

The Modified Heimlich maneuver or abdominal thrusts is the appropriate intervention for assisting a choking adult because it directly addresses the blockage of the airway. When someone is choking, their airway is obstructed, which prevents them from breathing effectively or at all. The Heimlich maneuver generates a quick, upward thrust on the abdomen to create enough pressure to expel the object blocking the airway, allowing the person to breathe again.

Other devices mentioned serve different purposes. An Automated External Defibrillator (AED) is utilized for delivering an electric shock to restore a normal heart rhythm in cases of cardiac arrest, not for choking emergencies. A Bag-Valve Mask (BVM) is a device used for providing positive pressure ventilation to a patient who cannot breathe adequately, but it is not suitable for clearing an obstruction. A Neuro Response System is typically associated with neurological assessments or interventions, which are irrelevant in the context of addressing choking. Thus, the Modified Heimlich maneuver or abdominal thrusts is the correct choice for this emergency situation.
