Frequently Asked Questions

What is an AED and how does it work?

An Automated External Defibrillator (AED) is a portable medical device designed to treat sudden cardiac arrest (SCA), a condition where the heart unexpectedly stops beating. The AED analyzes the heart's rhythm and, if necessary, delivers an electrical shock, or defibrillation, to help the heart re-establish an effective rhythm. Here's how an AED works: 1. **Power On**: The user turns on the AED, which can be done by pressing a button or opening the device's lid, depending on the model. 2. **Attach Electrodes**: The device includes adhesive electrode pads that must be placed on the patient's bare chest. One pad is placed on the upper right side of the chest, and the other on the lower left side, below the armpit. 3. **Analyze Heart Rhythm**: Once the pads are attached, the AED automatically analyzes the heart's electrical activity to determine if a shock is needed. The device uses built-in algorithms to assess the heart rhythm. 4. **Shock Advisory**: If the AED determines that defibrillation is necessary, it will advise the user to deliver a shock. Some AEDs are fully automatic and will deliver the shock without user intervention, while semi-automatic models require the user to press a button to administer the shock. 5. **Deliver Shock**: The shock is delivered through the electrode pads, momentarily stopping the heart's electrical activity, allowing it to potentially restart with a normal rhythm. 6. **CPR Guidance**: After the shock, the AED may provide audio or visual prompts to guide the user in performing cardiopulmonary resuscitation (CPR) until emergency medical services arrive. AEDs are designed to be user-friendly, with voice prompts and visual cues to assist even untrained bystanders in providing life-saving care during a cardiac emergency.

How do you use an AED in an emergency?

1. **Ensure Safety**: Check the scene for safety. Ensure the victim and bystanders are safe from hazards like traffic or electrical sources. 2. **Assess the Victim**: Check for responsiveness by gently shaking the person and shouting. If unresponsive, call emergency services immediately or have someone else do it. 3. **Begin CPR**: Start CPR if the person is not breathing or only gasping. Push hard and fast in the center of the chest at a rate of 100-120 compressions per minute. 4. **Retrieve AED**: Send someone to get an AED if available. Continue CPR until the AED arrives. 5. **Turn on the AED**: Open the AED case and turn it on. Follow the voice prompts or visual instructions provided by the device. 6. **Attach Pads**: Expose the victim’s chest. Peel the backing off the AED pads and attach them to the victim’s bare chest as indicated on the pads—one pad on the upper right side and the other on the lower left side of the chest. 7. **Analyze Rhythm**: Ensure no one is touching the victim. The AED will automatically analyze the heart rhythm. Follow the AED prompts. 8. **Deliver Shock**: If the AED advises a shock, ensure everyone is clear of the victim. Press the shock button when prompted. 9. **Continue CPR**: After the shock, or if no shock is advised, immediately resume CPR starting with chest compressions. Continue to follow AED prompts. 10. **Repeat**: Continue cycles of CPR and follow AED prompts until emergency medical personnel arrive or the victim shows signs of life. 11. **Post-Use**: Once help arrives, provide them with information about the incident and AED use.

What is the difference between CPR and AED?

CPR (Cardiopulmonary Resuscitation) and AED (Automated External Defibrillator) are both critical components in the chain of survival during cardiac emergencies, but they serve different functions. CPR is a manual procedure that involves chest compressions and rescue breaths. Its primary purpose is to maintain circulation and oxygenation in a person whose heart has stopped beating. By performing chest compressions, a rescuer manually pumps blood through the heart and to vital organs, while rescue breaths provide oxygen to the lungs. CPR is crucial in sustaining life until more advanced medical help can be administered. On the other hand, an AED is a portable electronic device that automatically diagnoses life-threatening cardiac arrhythmias, such as ventricular fibrillation and pulseless ventricular tachycardia. It delivers an electrical shock to the heart to restore a normal rhythm. AEDs are designed to be user-friendly, with voice prompts and visual instructions to guide even untrained bystanders through the defibrillation process. The device analyzes the heart's rhythm and determines if a shock is necessary, ensuring that it is only delivered when appropriate. In summary, CPR is a manual technique used to maintain blood flow and oxygenation, while an AED is a device that can restore a normal heart rhythm through defibrillation. Both are essential in cardiac arrest situations, with CPR providing immediate support and AEDs offering a potential solution to restart the heart. Together, they significantly increase the chances of survival and recovery in cardiac emergencies.

Where should AEDs be stored for easy access?

AEDs (Automated External Defibrillators) should be stored in locations that are easily accessible, highly visible, and known to all potential users. Here are key considerations for optimal AED placement: 1. **High-Traffic Areas**: Place AEDs in areas with high foot traffic to ensure quick access. This includes lobbies, main hallways, and near entrances. 2. **Central Locations**: Position AEDs centrally within a facility to minimize the time it takes to retrieve them from any point within the building. 3. **Near High-Risk Areas**: Install AEDs near areas where cardiac arrest is more likely, such as gyms, sports facilities, and areas where physical exertion is common. 4. **Public Spaces**: In public buildings, AEDs should be placed in locations like airports, shopping malls, and stadiums where large crowds gather. 5. **Visible and Clearly Marked**: AEDs should be in clearly marked cabinets or cases with signage that is visible from a distance.
