As well as being used extensively by emergency medical personnel, many buildings and organisations now keep AEDs available, typically under the charge of the resident trained First Aiders who will likely have been trained in their use. AEDs are also increasingly used aboard various types of transportation.
In some areas, AEDs are featured prominently in public areas, particularly in busy places with a high volume of foot traffic. In these cases the devices are highlighted in order to be easy to see and access should a person suffer a cardiac incident.
The availability of AEDs has vastly improved in recent years, and the affordability of the devices has seen many people opt to have them in their homes, perhaps in cases where someone living in the home has a known heart condition. Of course these machines cannot replace the expertise of trained medical professionals, but in cases where the person administering the treatment has been trained, AEDs can save lives by acting promptly in that crucial time period immediately following cardiac difficulties.
