Doctors recommend equipping public spaces with automated external defibrillators (AEDs) as they can save lives during the critical "golden hour" following sudden cardiac arrest.

Many "golden opportunities" to save lives in Vietnam are missed due to the hesitation and lack of first aid knowledge of bystanders, according to a representative of the Ho Chi Minh City 115 Emergency Center.
