What conditions may warrant the use of an AED on a child?

The use of an AED (Automated External Defibrillator) on a child is warranted primarily in cases of cardiac arrest, which is indicated by loss of consciousness and unresponsiveness coupled with no breathing. In such situations, the heart may be experiencing a lethal arrhythmia that could lead to death if not addressed promptly. Administering an AED can help restore a normal heart rhythm by delivering an electric shock, thus significantly increasing the chances of survival when used as soon as possible after cardiac arrest is suspected.

The other scenarios represent conditions that do not typically necessitate AED use. Wheezing with a history of asthma suggests respiratory distress rather than cardiac arrest, and while it requires medical attention, it is not an indication for AED deployment. Bleeding from an extremity indicates a traumatic injury that needs first aid but is unrelated to heart function. Similarly, stinging pain from a bite does not imply a cardiac emergency and would not require the use of an AED.
