Our Impact News What is a defibrillator and how does it work? A defibrillator, or AED (automated external defibrillator), is a life-saving medical device that delivers a shock to a patient in cardiac arrest, helping to restore normal heart rhythm. AEDs are built so that anyone, even without medical training, can use them in an emergency. Why are defibrillators important? Around quarter of the missions our team respond to are cardiac related. Our crew can be anywhere within Dorset and Somerset within 20 minutes, but the care the patient receives before we get there can play a vital role in saving their life. Early CPR and defibrillation can double chances of survival. To find out more about why it is important to act quickly to deliver CPR and defibrillation in an emergency, click here. How do you use a defibrillator? A defibrillator is designed to be easy to use in an emergency, even for inexperienced users. Once switched on, it automatically analyses the patient’s condition and deliver shocks if needed. You do not need specialist training to use an AED. The device provides clear voice instructions and visual prompts to guide you the process step by step.
