Fact vs Myth

Defibrillators are life-saving devices that have become crucial in emergency medical situations, particularly during sudden cardiac arrest (SCA). However, despite their importance, many myths surround their use and effectiveness. In this blog, we will dispel some common myths and present the facts to provide a clearer understanding of defibrillators.

Myth 1: Defibrillators are only for medical professionals

Fact: Modern defibrillators, especially Automated External Defibrillators (AEDs), are designed for use by the general public. AEDs provide clear, step-by-step voice instructions and are equipped with sensors that analyse the patient’s heart rhythm. They only deliver a shock if it’s necessary, ensuring they can be safely used by anyone, even without medical training.

Myth 2: Defibrillators always restart a stopped heart

Fact: Defibrillators are used to correct abnormal heart rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia, not to restart a heart that has completely stopped. They work by delivering an electric shock to reset the heart’s electrical activity, allowing a normal rhythm to resume. If the heart has completely stopped, CPR (cardiopulmonary resuscitation) is essential alongside defibrillation efforts.

Myth 3: Using a defibrillator can cause more harm than good

Fact: AEDs are designed with safety features to minimise the risk of misuse. They will not deliver a shock unless it’s medically necessary. The benefits of using a defibrillator far outweigh the risks, as timely defibrillation significantly increases the chance of survival in cases of sudden cardiac arrest.

Myth 4: Defibrillators are too expensive for public places

Fact: While defibrillators can be a significant investment, their prices have decreased over the years, making them more accessible. Many communities, businesses, and public spaces recognise their value and have made efforts to install AEDs in accessible locations. Grants and fundraising campaigns also help offset costs, highlighting the communal responsibility in ensuring public safety.

Myth 5: You can’t use a defibrillator on someone with a pacemaker

Fact: AEDs can be used on individuals with pacemakers. When applying the AED pads, they should be placed at least an inch away from the pacemaker device to avoid interference. Defibrillators are designed to adjust their operation based on the patient’s condition, making them safe to use even in such situations.

Myth 6: If you use a defibrillator incorrectly, you can be sued

Fact: Good Samaritan laws in many regions protect individuals who assist in emergencies, including using AEDs, from legal liability. These laws are intended to encourage bystanders to help without fear of legal repercussions, if they act in good faith and within their training. Read more about Good Samaritan laws.

Myth 7: Defibrillators are difficult to maintain

Fact: AEDs require minimal maintenance. Regular checks include ensuring the battery is charged and the electrodes are within their expiration date. Many AEDs perform self-checks and provide alerts if maintenance is needed. Following the manufacturer’s guidelines helps keep the device ready for use. Check out our AED maintenance tips.

Myth 8: Only older adults need defibrillators

Fact: Sudden cardiac arrest can occur in people of all ages, including children and young athletes. Having AEDs available in schools, sports facilities, and other public areas ensures a rapid response, which is critical for survival regardless of the victim’s age. Learn about AEDs for schools and sports facilities.

So..

Understanding the facts about defibrillators is crucial in appreciating their role in saving lives. By dispelling these myths, we hope to encourage more people to become informed and feel confident in using AEDs during emergencies. Remember, in the case of cardiac arrest, every second counts, and a defibrillator can be the difference between life and death.
