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, known as defibrillation, to help the heart re-establish an effective rhythm. AEDs are user-friendly and can be operated by laypersons with minimal training. They consist of a main unit with a computer processor, electrodes (pads), and a battery. When someone experiences SCA, the AED is turned on and the electrodes are attached to the patient's bare chest. The device then automatically assesses the heart's rhythm to determine if a shock is needed. If the AED detects a shockable rhythm, such as ventricular fibrillation or pulseless ventricular tachycardia, it instructs the user to ensure no one is touching the patient and to press the shock button. The shock delivered by the AED depolarizes the heart muscles, stopping the chaotic rhythm and allowing the heart's natural pacemaker to potentially restore a normal rhythm. AEDs also provide voice prompts and visual cues to guide the user through the process, including CPR instructions if needed. Modern AEDs are equipped with safety features to prevent inappropriate shocks, ensuring they only deliver a shock when necessary. The timely use of an AED, ideally within minutes of collapse, significantly increases the chances of survival and recovery for SCA victims. AEDs are commonly found in public places such as airports, schools, and sports facilities, making them accessible during emergencies.

1. **Ensure Safety**: Check the scene for safety. Ensure the person needs help by tapping their shoulder and asking loudly, "Are you okay?" 2. **Call for Help**: If unresponsive, call emergency services or ask someone else to do so. If available, get an Automated External Defibrillator (AED). 3. **Position the Person**: Lay the person on their back on a firm, flat surface. 4. **Chest Compressions**: - Kneel beside the person. - Place the heel of one hand on the center of the chest, between the nipples. - Place your other hand on top, interlocking your fingers. - Keep your elbows straight and shoulders directly above your hands. - Use your body weight to compress the chest at least 2 inches deep. - Perform compressions at a rate of 100-120 per minute. Allow the chest to fully recoil between compressions. 5. **Rescue Breaths** (if trained and willing): - After 30 compressions, open the airway using the head-tilt, chin-lift method. - Pinch the nose shut, take a normal breath, and seal your lips around the person's mouth. - Give 2 breaths, each lasting about 1 second, watching for chest rise. - Continue with cycles of 30 compressions and 2 breaths. 6. **Use an AED**: As soon as it arrives, turn it on and follow the voice prompts. Attach the pads to the person's bare chest as instructed. 7. **Continue CPR**: Keep performing CPR until emergency personnel arrive, the person shows signs of life, or you are too exhausted to continue. 8. **Post-CPR Care**: If the person starts breathing, place them in the recovery position and monitor until help arrives.

CPR and AED training should typically be renewed every two years. This recommendation is based on guidelines from major health organizations such as the American Heart Association (AHA) and the Red Cross. These organizations suggest a biennial renewal to ensure that individuals remain proficient in the latest techniques and guidelines, as CPR and AED protocols can evolve based on new research and findings. Regular renewal helps maintain the skills and confidence necessary to effectively respond in emergency situations.

Anyone can use an Automated External Defibrillator (AED) without special training, as AEDs are designed to be user-friendly and provide clear, step-by-step voice and visual instructions. However, while formal training is not required, it is highly recommended. Training courses, such as those offered by the American Heart Association or the Red Cross, can increase confidence and effectiveness in using an AED during an emergency. AEDs are equipped with sensors to assess the heart's rhythm and determine if a shock is necessary. They will not deliver a shock unless it is needed, minimizing the risk of misuse. The device guides the user through the process, from attaching the electrode pads to delivering the shock if required. Training provides additional skills, such as recognizing cardiac arrest symptoms, performing CPR, and understanding the AED's functions more thoroughly. It also helps individuals remain calm and act quickly in high-pressure situations, which can improve the chances of survival for the victim. In summary, while anyone can use an AED, training enhances the ability to respond effectively in emergencies.

Adult CPR involves using both hands to deliver chest compressions at a depth of about 2 inches, with a compression rate of 100-120 per minute. Rescue breaths are given after every 30 compressions, with the head tilted back to open the airway. For children, CPR is similar but with some modifications. Compressions are delivered with one hand for smaller children, at a depth of about 2 inches or one-third the chest's depth. The compression rate remains the same. Rescue breaths are also given after every 30 compressions, but care is taken to use less force when tilting the head and delivering breaths. For infants, CPR involves using two fingers for compressions at a depth of about 1.5 inches or one-third the chest's depth, with a compression rate of 100-120 per minute. Rescue breaths are given after every 30 compressions, with the rescuer covering the infant's nose and mouth with their mouth. In all cases, CPR should be continued until emergency services arrive or the person shows signs of life.
