When someone experiences sudden cardiac arrest, their chances of survival decrease with every passing minute. In these critical moments, being able to use an automated external defibrillator (AED) can mean the difference between life and death. AEDs are user-friendly devices designed to deliver a controlled electric shock to the heart, potentially restoring its normal rhythm. While professional medical assistance should always be sought, knowing how to operate an AED properly can allow bystanders to take lifesaving action until emergency responders arrive. In this comprehensive guide, we'll walk you through the step-by-step process of using an AED on adults, children, and infants.
Using an AED on an Adult
Recognize the Emergency: If an adult is unresponsive and not breathing normally, call emergency services immediately and locate the nearest AED.
Prepare the Area: Move the person to a firm, flat surface if possible. Remove any metal objects from their chest area and ensure the chest is dry.
Turn on the AED: Open the AED case and follow the voice prompts or visual indicators to turn it on.
Apply the Pads: Remove the pads from their packaging and place them on the person's bare chest, as illustrated on the pads or AED case. One pad should be placed below the right collarbone, and the other should be placed on the left side of the chest, a few inches below the armpit.
Allow the AED to Analyze: Once the pads are properly placed, the AED will analyze the person's heart rhythm. Do not touch the person during this process.
Deliver the Shock: If the AED detects a shockable rhythm, it will prompt you to deliver a shock. Stand clear and ensure no one is touching the person. Press the "shock" button when instructed.
Resume CPR: After the shock, the AED will prompt you to resume CPR. Perform chest compressions and rescue breaths according to your level of training until emergency services arrive or the person starts breathing normally.
Using an AED on a Child:
The process for using an AED on a child (age 1 to 8 years) is similar to that for an adult, with a few key differences:
Use Pediatric Pads: If available, use pediatric pads designed for children. If not, use the adult pads but position them differently, with one pad on the child's bare chest and the other on their back, between the shoulder blades.
Adjust Energy Level: Some AEDs have a "child" mode or key that reduces the energy level of the shock to a level appropriate for a child's smaller body size.
Follow AED Prompts: As with adults, follow the AED's voice prompts or visual indicators for proper pad placement and when to deliver shocks.
Resume Child CPR: After a shock, resume child CPR (rescue breaths and chest compressions) until emergency services arrive or the child starts breathing normally.
Using an AED on an Infant:
Using an AED on an infant (under 1 year old) requires additional precautions:
Confirm Infant Cardiac Arrest: Ensure the infant is unresponsive, not breathing normally, and has no pulse before attempting to use an AED.
Use Pediatric Pads or Manual Override: If available, use pediatric pads designed for infants. If not, most AEDs have a manual override or "infant" mode that reduces the energy level further. Consult the AED's instructions for this process.
Pad Placement: Place one pad on the infant's bare chest, and the other pad on their back, between the shoulder blades.
Deliver Shocks as Prompted: Follow the AED's prompts for delivering shocks, ensuring no one is touching the infant during the analysis and shock delivery.
Resume Infant CPR: After a shock, immediately resume infant CPR (rescue breaths and chest compressions) until emergency services arrive or the infant starts breathing normally.
Important Considerations:
Call Emergency Services: Always call emergency services as soon as possible when responding to a cardiac emergency. An AED should only be used as an interim measure until professional help arrives.
Check for Safety: Before using an AED, ensure the scene is safe and clear any metal objects from the person's chest area to prevent potential burns or interference.
Follow AED Prompts: Modern AEDs are designed to provide clear voice and visual prompts, guiding users through each step of the process. Follow these prompts carefully to ensure proper usage.
Continue CPR: Even after delivering shocks with an AED, it's crucial to continue performing CPR until emergency responders arrive or the person starts breathing normally.
Seek Training: While AEDs are designed to be user-friendly, it's highly recommended to receive formal training in CPR and AED usage. This training can help build confidence and ensure proper technique in emergency situations.
By following these step-by-step guidelines for using an AED on adults, children, and infants, bystanders can take quick and potentially life-saving action during cardiac emergencies. Remember, every second counts, and using an AED properly can significantly increase a person's chances of survival while waiting for professional medical assistance to arrive.
