Final answer:
An AED automatically diagnoses heart conditions and prompts users to deliver a shock by pressing a button. It provides essential assistance in cardiac emergencies, and CPR is typically recommended before AED use.
Step-by-step explanation:
The Automated External Defibrillator (AED) will deliver a shock, charges itself, prompts that everyone is clear, and prompts rescuers to press the shock button. The AED is a portable device that is designed to be used by laypersons. It automatically diagnoses the patient's heart condition through electrocardiogram analysis and then applies an electrical shock with the appropriate energy and waveform to correct abnormal heart rhythms such as ventricular fibrillation.
The current delivered by the AED interrupts the chaotic electrical activity of a heart experiencing arrhythmia, effectively rebooting the heart to allow its natural pacemaker to restore a normal rhythm. CPR is often recommended prior to AED use.
In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator delivers a large charge or shock to a person's heart to correct abnormal heart rhythm. The AED automatically diagnoses the heart condition and then applies the shock with appropriate energy and waveform. CPR is recommended in many cases before using a defibrillator.
