The benefits and use of shock advisory defibrillators in hospitals.

Survival to discharge following a cardiac arrest is dependent on rapid and effective basic and advanced life support. Paramount to a rapid response is access to sufficiently trained health care providers, who have a duty to perform basic life support and initiate early defibrillation. In hospitals, defibrillation remains the domain of specially prepared staff and the type of defibrillator used might be crucial to rapid and effective defibrillation. The advent of automatic external defibrillators has increased the range of people who can use a defibrillator successfully. For nurses, arguably a lack of familiarity about the benefits of and the use of automatic external defibrillators are the greatest barriers to nurse-initiated defibrillation programmes. This paper explores the use of automatic external defibrillators, their relationship to the associated defibrillator waveforms and the benefits of their use by registered nurses within the hospital setting.
