Cultural Tip
In many Spanish‑speaking countries, AEDs are installed in schools, gyms, and public transport stations. The term ‘DEA’ (Desfibrilador Externo Automático) is the standard, but you may also hear ‘desfibrilador automático’ or simply ‘desfibrilador’. When asking about it, keep a calm tone; emergency equipment is taken seriously, and offering to help operate it can be seen as courteous.
