AED units can be found in many locations and in different storage boxes. In earlier editions of the First Aid Show we looked at the lockable outside boxes and now we will look at a box you would commonly find in a building and discuss where to find them. AED units are all basically the same although they look different or have different features. All have a on/off button and a shock button, the rest of the information on what to do is given in voice prompts by the unit. For more information on AED training see our AED Video Online Training website.
