When and How An AED Should Be Used

Imagine being able to save a life with just a few simple steps. This is the power of Automated External Defibrillators (AEDs) and cardiopulmonary resuscitation (CPR) when used together during sudden cardiac arrest events. An AED should be used in conjunction with CPR for the best possible outcome. Are you ready to learn more about this life-saving technology and how you can make a difference in an emergency? Let’s dive in.

Understanding Sudden Cardiac Arrest

Understanding Sudden Cardiac Arrest

Sudden cardiac arrest is a medical emergency characterized by a disruption in the heart’s electrical activity, resulting in a fast heartbeat (ventricular tachycardia) or a fast and irregular heartbeat (ventricular fibrillation). One should be aware that sudden cardiac arrest is not the same as a heart attack, which is caused by a blockage in blood flow to the heart.

In cases of sudden cardiac arrest, quick action to begin CPR and use an AED can save lives by keeping the blood flowing to vital organs and restoring the heart’s rhythm.

Given that about 80% of sudden cardiac arrest cases happen at home, it’s pivotal to formulate an emergency action plan. Being prepared with first aid training, which includes CPR and AED use, equips you with the skills needed to tackle life-threatening situations effectively.

The Role of AEDs in CPR

The Role of AEDs in CPR

AEDs are an essential component of CPR, working together with rescue breaths to improve survival rates. Although CPR can sustain blood flow to the heart and brain, typically only defibrillation can reestablish the heart’s rhythm.

Utilizing AEDs during CPR can improve the chances of survival in the event of cardiac arrest. Being aware of when to initiate CPR and operate an AED can drastically alter survival outcomes.

Advantages of AEDs

An AED (Automated External Defibrillator) is a device that assesses heart function and provides electrical shocks to restart the heart, making them vital in saving lives during sudden cardiac arrest. The success rate of automated external defibrillators in restarting a heart during cardiac arrest is high if used within the first few minutes, but the survival rate decreases by 7-10% for every minute that defibrillation is delayed.

While manual CPR focuses on manually pumping blood to vital organs and providing artificial respiration, AEDs can deliver a controlled electric shock to the heart to restore its normal rhythm. Research has demonstrated that AEDs have a considerable influence on overall survival rates in sudden cardiac arrest cases. Before initiating CPR and employing an AED, it’s critical to assess the victim’s normal breathing pattern.

AED Deployment

When a sudden cardiac arrest occurs, every second counts. Locating an AED and starting CPR immediately can make a significant difference in the victim’s chances of survival. While waiting for the AED to arrive, performing CPR can help maintain blood flow to the vital organs.

For effective defibrillation, the correct positioning of AED pads on the person’s chest is of utmost importance. One must ensure that the pads are positioned at least 1 inch apart from any implanted devices on the victim’s chest. When using an AED, it is necessary to follow the provided prompts and instructions, which include analyzing the heart rhythm and delivering a shock if required.

Proper Usage of AEDs

Proper Usage of AEDs

For effective use of an AED, adherence to the manufacturer’s user manual for safety guidelines, operational procedures, and maintenance directives is critical. This includes:

  1. Evaluating the situation

  2. Assessing the victim’s responsiveness and breathing

  3. Requesting assistance or emergency services

  4. Activating the AED

  5. Connecting the electrode pads to the victim’s chest

  6. Plugging in the AED machine if necessary

  7. Following the directions given by the AED.

It is not recommended to utilize an AED in wet conditions or when submerged in water, as it could potentially cause harm to both the victim and the person providing care. In cases where the victim is submerged in water during a cardiac arrest, they should be moved to dry land before administering an AED shock.

Assessing the Situation

Prior to approaching a cardiac arrest victim, it’s vital to assess the area and ascertain safety. To assess consciousness, tap the victim’s shoulder and ask, “Are you okay?” If no response is elicited, the victim is likely unconscious. Observe their breathing for indications of abnormality, such as gasping for air, irregular or noisy breaths, and agonal respiration. In such cases, chest compressions might be required as part of the resuscitation process.

If the victim is breathing normally, remain with them until the ambulance arrives.

Preparing the Victim

Before applying AED pads to a person’s chest, follow these steps:

  1. Remove their shirt and dry the person’s chest thoroughly.

  2. Remove some hair from the victim’s chest to ensure electrode pads stick properly. This is especially important if the victim has a lot of body hair.

  3. If you are unable to locate a razor, gently apply pressure to ensure the pads are positioned as close to the victim’s chest as possible.

For the effectiveness of the AED pads, it’s critical that they maintain direct contact with the patient’s skin.

Special Considerations for AED Use

Special Considerations for AED Use

Special circumstances like children and individuals with pacemakers need to be taken into account while using an AED. Pediatric AED pads or a pediatric electrical setting should not be used on a child older than 8 years or weighing more than 55 pounds (25 kg). If pediatric pads are not available, adult pads can be used, although they may need to be applied differently.

It’s generally safe to use an AED on a person with a pacemaker, but proper pad placement and following user manual instructions are crucial.

AEDs and Children

AEDs can be safely used on young children under 8 years old and even infants. When using AEDs on children, pediatric attenuated pads should be used. Adherence to the manufacturer’s directions for pad placement on infants and children is vital.

Medical textbooks, online resources, and CPR and AED training courses can provide information on the resuscitation of infants and children.

AEDs and Pacemakers

In the case of an individual with a pacemaker, follow these steps when using an AED:

  1. Activate the AED and follow the audio instructions.

  2. Remove any clothing around the chest area.

  3. Identify the pacemaker.

  4. Avoid placing the electrode pads directly over the internal device.

  5. Instead, position the electrode pads at least 1 inch away from the pacemaker.

The recommended placement of AED pads on a patient with a pacemaker is at least 3 cm away from the pacemaker and around the upper right side of the chest. Following these guidelines ensures the safety and effectiveness of AED use on individuals with pacemakers.

Importance of AED and CPR Training

Importance of AED and CPR Training

Comprehending the significance of CPR AED and acquiring appropriate training in both CPR and AED use is fundamental to performing a successful sudden cardiac arrest rescue. Organizations like the American Red Cross and the American Heart Association offer a wide selection of courses, ranging from basic first aid to advanced professional training, including digital-only options. These courses typically encompass:

  • Recognizing and responding to cardiac emergencies

  • Executing CPR

  • Employing an automated external defibrillator (AED)

  • Furnishing first aid for a variety of injuries and medical emergencies

Acquiring appropriate training to perform CPR and AED use is essential to raise the prospects of rescuing lives in the event of sudden cardiac arrest, as cardiopulmonary resuscitation is a crucial skill in such situations.

CPR and AED Meaning

The term “CPR AED meaning” encompasses two critical life-saving techniques. “CPR” stands for Cardiopulmonary Resuscitation, a procedure that involves chest compressions and sometimes rescue breaths to maintain blood circulation and oxygen flow when the heart stops beating. On the other hand, “AED” refers to an Automated External Defibrillator, a device specifically designed to deliver electric shocks to a heart in cardiac arrest to attempt to restore its normal rhythm. Together, CPR and AED offer a comprehensive approach to tackling cardiac emergencies.

AED Availability and Accessibility

Having an AED nearby can be beneficial in reviving a person with ventricular fibrillation or ventricular tachycardia by saving valuable time. The presence of an AED in close proximity can significantly reduce the time taken to respond to a sudden cardiac arrest episode. Prior to purchasing an AED for your home, consulting with a healthcare professional and conducting comprehensive research is a must.

Furthermore, familiarizing yourself with the basics of CPR and ensuring that the AED is functioning properly is also significant.


In conclusion, AEDs and CPR are powerful tools that can save lives during sudden cardiac arrest events. Understanding the differences between cardiac arrest and heart attack, proper usage of AEDs, special considerations for children and individuals with pacemakers, and the importance of training and accessibility can make all the difference in an emergency. By being prepared and educated, you can take control of a life-threatening situation and potentially save a life.
