For medical professionals and caregivers, understanding the definition of a “child” in the context of Cardiopulmonary Resuscitation (CPR) and Automated External Defibrillator (AED) use is crucial. According to the American Heart Association (AHA), correctly identifying whether a patient is an infant, child, or adult is essential for providing the most effective emergency care during a cardiac arrest. This distinction guides the techniques used, ensuring the safety and efficacy of resuscitation efforts. In CPR and AED protocols, the term “child” has a very specific meaning that dictates the approach to life-saving interventions.
Defining a “Child” in CPR/AED – The AHA Standard
The American Heart Association (AHA) defines a “child” in CPR and AED guidelines as anyone between one year of age and the onset of puberty. This age range includes individuals who have passed infancy but have not yet developed secondary sexual characteristics indicative of adolescence. Puberty, in this context, refers to the stage of physical development where a person begins to show signs of sexual maturation, such as muscle development and other bodily changes associated with adolescence. This definition is critical because CPR and AED techniques are adapted based on physiological differences across age groups.
The Importance of Age Categories in CPR and AED Procedures
Defining a “child” is not arbitrary; it serves a vital purpose in emergency cardiac care. The primary reason for this classification is to ensure that the correct force is applied during chest compressions and that the AED is used appropriately. Applying adult CPR techniques to a child, or vice versa, can be ineffective and potentially harmful. Children have smaller bodies and developing organs that require a gentler approach compared to adults. Incorrect technique can lead to injuries and reduce the chances of successful resuscitation.
Key Differences: Child CPR vs. Adult CPR Techniques
While the fundamental goal of CPR remains the same across all age groups—to restore breathing and circulation—the specific techniques are modified for children. Here are the key differences:
1. Chest Compression Depth and Technique
- Child CPR: Chest compressions for children should be approximately 2 inches (5 cm) deep, which is about one-third the depth of the chest. Rescuers can use one or two hands to perform compressions, depending on the size of the child. The technique should be adjusted to ensure the appropriate depth is achieved without excessive force.
- Adult CPR: In contrast, adult CPR requires chest compressions to be at least 2 inches (approximately 5 cm) deep, and typically involves the use of both hands to deliver sufficient force.
2. Compression-to-Breath Ratio
- Child CPR: For a single rescuer performing CPR on a child, the recommended compression-to-breath ratio is 30:2 (30 chest compressions followed by 2 rescue breaths). However, if there are two rescuers, this ratio changes to 15:2 to optimize efficiency and reduce rescuer fatigue.
- Adult CPR: For adults, the compression-to-breath ratio remains 30:2 regardless of whether there is one rescuer or two. This difference reflects the common causes of cardiac arrest in children, which are often respiratory-related.
3. AED Pad Placement
- Child AED Use: When using an AED on a child who is under 8 years old or weighs less than 55 pounds (25 kg), pediatric AED pads are necessary if available. These pads are designed to deliver a lower, more appropriate dose of electrical shock. The placement for pediatric pads is typically on the chest and back of the child, known as anterior-posterior positioning. This placement ensures the electrical current passes through the heart effectively.
- Adult AED Use: Adult AED pad placement is on the upper right chest and the lower left side of the chest (anterolateral). These pads are larger and deliver a higher dose of electrical energy suitable for adults.
AED Application in Children: Essential Considerations
Using an AED on a child necessitates special considerations to maximize safety and effectiveness. Here’s what to keep in mind:
Pediatric AED Pads: Reducing Shock Energy
Most modern AEDs are equipped with pediatric pads or a pediatric attenuator, which reduces the standard adult dose of electrical shock. Pediatric pads are crucial for children under the age of 8 or weighing less than 55 pounds because they deliver a weaker, more appropriate electrical current, minimizing the risk of harming the child’s heart. If your AED kit includes pediatric pads, they should always be used for children in this age and weight category.
Automatic AED Shock Adjustments for Children
Many advanced AEDs can automatically adjust the energy level when pediatric pads are connected. This feature is designed to ensure that the child receives a shock that is strong enough to be effective but not so strong as to cause damage. This automatic adjustment is a significant safety feature, simplifying the process for rescuers in high-stress situations.
Step-by-Step Guide: How to Use an AED on a Child
Using an AED on a child follows a similar process to adult AED use, with key modifications:
-
Power On: Turn on the AED and follow the device’s voice prompts. AEDs are designed to guide users through each step of the process with clear, spoken instructions.
-
Pad Placement: Place the pediatric AED pads on the child’s chest and back as indicated on the pads or by the AED voice prompts. Ensure good contact with the skin, which may require quickly drying the chest if it is wet and removing clothing.

-
Analyze Heart Rhythm: Ensure no one, including yourself, is touching the child while the AED analyzes the heart rhythm. Touching the child during analysis can interfere with the AED’s reading and potentially cause harm.
-
Deliver Shock (If Advised): If the AED advises a shock, ensure again that everyone is clear of the child and press the “shock” button. The AED will announce when to deliver the shock.
-
Resume CPR: Immediately after delivering the shock (or if no shock is advised), resume CPR, starting with chest compressions. Continue CPR until emergency medical services arrive or the child shows signs of recovery, such as movement or breathing.
When is AED Use Necessary for a Child?
An AED should be used on a child if they are unresponsive and not breathing normally or are only gasping. In these critical situations, an AED can be a life-saving intervention. It should be applied as quickly as possible, ideally after completing one cycle of CPR (30 chest compressions and 2 rescue breaths) if you are trained in CPR. The sooner an AED is used in cases of sudden cardiac arrest, the higher the chances of survival.
Child CPR: A Step-by-Step Emergency Guide
When faced with a child who is unresponsive, prompt and confident action is vital. Here’s a detailed step-by-step guide for performing CPR on a child:
Step 1: Assess Responsiveness
Gently tap the child’s shoulder and shout, asking loudly if they are okay. Check for a response such as movement, opening eyes, or speaking. If there is no response, it’s crucial to proceed immediately.

Step 2: Open the Airway
To open the airway, place one hand on the child’s forehead and gently tilt the head back. Simultaneously, use the fingers of your other hand to lift the chin forward. This maneuver helps to lift the tongue away from the back of the throat, clearing the airway.
Step 3: Check for Breathing
After opening the airway, look, listen, and feel for normal breathing for no more than 10 seconds. Look for chest rise and fall, listen for breath sounds, and feel for breath on your cheek. If the child is not breathing or is only gasping (ineffective breathing), it’s time to begin CPR.
Step 4: Initiate Chest Compressions
- Positioning: Place the heel of one or two hands in the center of the child’s chest, on the lower half of the breastbone. For smaller children, one hand may be sufficient; for larger children, you may need two hands, similar to adult CPR, but with less force.
- Compression Depth: Compress the chest to a depth of approximately 2 inches (5 cm), which is about one-third the depth of the chest.
- Compression Rate: Perform compressions at a rate of 100-120 compressions per minute. Push hard and fast in the center of the chest.
- Recoil: Allow the chest to recoil fully after each compression. Complete recoil is important as it allows the heart to refill with blood.
Step 5: Deliver Rescue Breaths
- After every 30 chest compressions (or 15 if two rescuers), give 2 rescue breaths.
- Seal: Pinch the child’s nose closed with your thumb and forefinger, and cover the child’s mouth completely with your mouth to create a tight seal.
- Breath Delivery: Give 2 rescue breaths, each lasting about one second. Watch for the chest to rise with each breath, indicating that air is entering the lungs. Avoid giving breaths that are too forceful or too large, especially for infants and young children, as this can cause lung injury.
Step 6: Continue CPR Cycles
Continue cycles of 30 chest compressions and 2 rescue breaths (or 15:2 if two rescuers) without interruption until one of the following occurs:
- An AED becomes available and is ready to use.
- Emergency medical services (EMS) personnel arrive and take over care.
- The child begins to show signs of life, such as moving, breathing normally, or regaining consciousness.
- You become too exhausted to continue.
