Cardiac arrest is one of the leading causes of death globally. In the United States, more than 350,000 out-of-hospital cardiac arrests (OHCA) occur each year, with a survival rate of about 10%(American Heart Association).
Many of these deaths can be prevented if quick action is taken, particularly by using CPR (Cardiopulmonary Resuscitation) and an Automated External Defibrillator (AED).
For those in the Lower Rio Grande Valley in Texas, where access to immediate emergency care can be challenging due to rural geography, knowing how to use an AED can save lives. This step-by-step guide explains how AEDs work and how quick, informed action during a cardiac emergency can dramatically improve survival rates.
What Is an AED?
An AED is a portable device that delivers an electric shock to a person suffering from cardiac arrest. When a person’s heart stops beating or beats irregularly due to sudden cardiac arrest, the heart needs to be “reset” to its normal rhythm. This is where the AED comes into play. AEDs analyze the heart’s rhythm and, if necessary, deliver a shock to restore normal function.
The beauty of AEDs is that they are designed for public use. Even individuals without medical training can successfully operate an AED thanks to its clear voice prompts and visual instructions.
Why Quick Action with an AED Matters
Time is of the essence when it comes to cardiac arrest. When the heart stops, it stops pumping oxygenated blood to the brain and other vital organs. Brain damage can begin to occur within 4 to 6 minutes, and death can follow within 10 minutes. For each minute that passes without defibrillation, the chances of survival decrease by 7-10%(cpr.heart.org).
With quick intervention — specifically, starting CPR and applying an AED — a victim’s survival chances can be doubled or even tripled. This makes the availability of AEDs and the knowledge to use them crucial in saving lives, especially in rural areas like the Rio Grande Valley.
Step-by-Step Guide to Using an AED
Here’s a breakdown of how to effectively use an AED in an emergency:
- Step 1: Ensure the Scene is Safe
- Before using an AED, it’s crucial to assess the situation. Make sure that the environment around the victim is safe for both you and them. For example, if the victim is lying in water, it’s essential to move them to a dry area before using the AED. Safety comes first.
- Step 2: Call 911 and Begin CPR
- Immediately call 911 to ensure that emergency medical services are on their way. If another person is present, delegate the call to them while you start CPR.
CPR basics:
Check for responsiveness: Tap the person on their shoulders and shout, “Are you okay?” If there’s no response and they are not breathing or only gasping, begin CPR.
Perform chest compressions: Kneel beside the person and place one hand on top of the other, with your hands positioned in the center of their chest. Push hard and fast, about 2 inches deep, at a rate of 100 to 120 compressions per minute. If you’re unsure of the rhythm, use the beat of a song like “Stayin’ Alive” by the Bee Gees as a guide.
Continue performing chest compressions until the AED is available.
- Step 3: Turn On the AED
- Once the AED arrives, turn it on. Most AEDs have a clearly visible power button. Once powered on, the device will give you audio prompts and guide you through the process step by step.
- Step 4: Attach the AED Pads
The AED will come with two electrode pads, which need to be placed on the victim’s bare chest. - Here’s how to place the pads:
- Upper right chest: Place one pad just below the victim’s collarbone, on the right side of their chest.
Lower left chest: Place the other pad on the lower left side of the chest, just below the armpit.
The pads need to be positioned correctly to ensure the electrical shock passes through the heart. If you’re unsure of the placement, most AEDs have illustrations on the pads showing where they should be applied. - Note for Children: If the victim is a child, use pediatric pads if available. If they aren’t available, adult pads can be used. Place one pad on the chest and the other on the back.
Step 5: Allow the AED to Analyze
Once the pads are in place, the AED will analyze the heart’s rhythm. During this time, do not touch the victim. Any movement can interfere with the AED’s ability to properly assess the heart’s rhythm.
If the AED detects a shockable rhythm, it will advise a shock.
- Step 6: Administer the Shock (If Advised)
- If a shock is required, the AED will prompt you to press the shock button. Ensure no one is touching the victim and press the flashing button to deliver the shock. The shock is intended to reset the heart’s rhythm.
- Step 7: Continue CPR
- After the shock is delivered, the AED will advise you to continue CPR. Perform 30 chest compressions, followed by 2 rescue breaths, and continue following the AED’s prompts. The device will re-analyze the heart rhythm every 2 minutes and will administer another shock if necessary.
- Step 8: Wait for EMS
- Keep performing CPR and using the AED as instructed until emergency responders arrive and take over, or until the person shows signs of life, such as moving or breathing.
Common Mistakes to Avoid
While AEDs are straightforward to use, there are some common mistakes that should be avoided during an emergency:
Delaying AED Use: Many people hesitate, unsure if they are “qualified” to use the AED. Remember, AEDs are designed for use by anyone. Don’t wait — take action as soon as the AED is available.
Touching the Victim During Analysis or Shock: It’s important not to touch the person during the AED’s analysis or when the shock is being administered. Doing so can interfere with the device’s function and potentially harm the rescuer.
Not Continuing CPR: The AED is only one part of the life-saving equation. CPR should always be continued in between shocks to maintain circulation.
AED Access in the Lower Rio Grande Valley
Communities like those in the Lower Rio Grande Valley can benefit greatly from having AEDs readily accessible. Due to the mix of rural and urban areas, emergency medical services (EMS) response times can vary, making the presence of AEDs in public spaces even more critical.
While many public spaces, such as schools, gyms, and shopping centers, are equipped with AEDs, there is still a need for more devices in rural areas. According to the American Heart Association, bystander CPR and AED use are the key factors that can improve survival rates in cardiac arrest(
American Heart Association)(cpr.heart.org).
AED Training in the Rio Grande Valley
While AEDs are designed for anyone to use, CPR and AED training is still highly recommended. Local organizations like CPR Masters RGV in Mission, TX, provide comprehensive CPR and AED training courses. These training sessions ensure that people feel confident and ready to act when faced with a cardiac emergency.
Conclusion
Knowing how to use an AED can be the difference between life and death for someone experiencing cardiac arrest. Quick action, paired with proper use of an AED, can double or even triple a person’s chances of survival. Whether you’re at work, home, or in a public space, having the knowledge and confidence to use an AED can help save lives in the Lower Rio Grande Valley and beyond.
If you haven’t already, consider enrolling in a CPR and AED training course today. AEDs are designed for easy use, and with a little training, anyone can become a lifesaver.
