An Automated External Defibrillator (AED) is a portable electronic device designed to diagnose and treat life-threatening cardiac arrhythmias, specifically ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT). When cardiac arrest occurs, time is critical, and an AED can deliver an electric shock that helps restore the heart’s normal rhythm. In this blog post, we will explore the importance of AEDs, how they function, and how MyCPR NOW is contributing to AED awareness and providing comprehensive CPR and AED training to empower individuals to act confidently during cardiac emergencies.
Understanding AED
An AED is a small, lightweight, and easy-to-use device that can be operated by both trained and untrained individuals in an emergency. Its main function is to assess the heart's rhythm and deliver a controlled shock, known as defibrillation, if necessary. Early defibrillation is one of the most critical factors in treating sudden cardiac arrest (SCA), as it dramatically improves the chances of survival.
- How AEDs Save Lives: When a person experiences sudden cardiac arrest, the heart's normal electrical rhythm becomes chaotic or stops completely. Without immediate intervention, blood flow to the brain and vital organs ceases, leading to permanent damage or death. An AED can assess whether the heart requires a shock, and if so, it delivers one to restore the heart's natural rhythm.
How Does an AED Work?
AEDs are designed to be intuitive and guide users through the process of delivering life-saving care. Here’s a detailed breakdown of how an AED works:
1. Assess the Situation:
- Ensure Safety: Before approaching the victim, check the scene for safety hazards like traffic or electrical dangers. Ensure the safety of yourself, the victim, and others.
- Check Responsiveness: Tap the victim and shout to check for responsiveness. If the victim does not respond and shows no signs of life, move forward with the steps below.
2. Activate Emergency Medical Services (EMS):
- Call for Help: If you determine the victim is unresponsive, immediately call 911 or your local emergency number. If others are nearby, ask someone to call EMS while you begin using the AED.
3. Retrieve and Prepare the AED:
- Locate the AED: AEDs are often found in public places like airports, schools, gyms, and workplaces. They are typically housed in clearly marked boxes or cabinets.
- Turn on the AED: Follow the manufacturer's instructions to turn on the AED. Most AEDs automatically begin providing voice or visual prompts to guide you through the process.
4. Apply the AED Pads:
- Expose the Chest: Quickly remove clothing to expose the victim’s bare chest. If the chest is wet, wipe it dry before placing the pads.
- Attach the Pads: Attach the AED pads to the chest in the positions indicated by the diagrams on the pads (typically one pad is placed on the upper right chest and the other on the lower left).
- Ensure No Contact: Make sure no one is touching the victim when the AED is analyzing the heart's rhythm to avoid interference.
5. Analyze the Heart Rhythm:
- Stand Clear: The AED will automatically analyze the heart’s rhythm. Make sure everyone stands clear during this time to allow the device to accurately assess the situation.
6. Deliver the Shock (If Advised):
- Shock the Heart: If the AED detects a shockable rhythm, it will instruct you to press a button to deliver the shock. Ensure no one is in contact with the victim when the shock is delivered.
- Resume Care: After the shock, immediately follow the AED’s prompts, which may include performing CPR while the AED continues to monitor the heart.
7. Perform CPR and Follow AED Prompts:
- CPR Guidance: The AED will instruct you to continue CPR, guiding you through cycles of chest compressions and rescue breaths. Follow its prompts and continue alternating between CPR and shocks until emergency medical services arrive or the victim shows signs of recovery.
The Importance of AEDs in Cardiac Emergencies
Sudden cardiac arrest is one of the leading causes of death, but AEDs can significantly increase the chances of survival. Here are a few reasons why AEDs are indispensable during cardiac emergencies:
1. Immediate Treatment:
- Early Defibrillation Saves Lives: Every minute that passes without defibrillation reduces the victim's chance of survival by 7-10%. AEDs provide an immediate solution to restore a normal heart rhythm, which is vital for increasing the chances of survival and reducing long-term damage.
2. User-Friendly Design:
- For Everyone: AEDs are designed with simplicity in mind, so even individuals with no prior medical training can use them effectively. The clear voice and visual prompts guide bystanders through each step, ensuring proper use in high-pressure situations.
3. Accessibility:
- Readily Available: AEDs are becoming more widely available in public spaces, including shopping malls, schools, office buildings, and transportation hubs. This accessibility shortens the time to defibrillation, a key factor in survival.
- Community Effort: The more AEDs available in public spaces, the more resilient communities become in responding to cardiac emergencies, ensuring help is readily available in critical moments.
4. Community Resilience:
- AED Awareness: By promoting AED education and awareness, communities can better prepare for cardiac emergencies. With more individuals trained in AED use, communities become empowered to act confidently and quickly during an emergency, improving the overall response to cardiac events.
