The correct cpr ratio for child is one of the most important numbers any rescuer, parent, teacher, coach, or healthcare provider can commit to memory. For a single lay rescuer, the ratio is 30 compressions to 2 rescue breaths, the same as adult CPR. For two trained healthcare providers using the pediatric acls algorithm framework, the ratio shifts to 15 compressions to 2 breaths to deliver more oxygen-rich blood to a child whose cardiac arrest is most often respiratory in origin.
Understanding why this ratio exists matters as much as memorizing it. Children rarely collapse from primary cardiac events the way adults do. Instead, pediatric arrest usually begins with a breathing problem such as drowning, choking, asthma, or trauma. Because hypoxia is the root cause, increasing the proportion of rescue breaths with a partner improves survival and neurologic outcomes. This is the foundation behind every modern pediatric resuscitation guideline taught today.
The American Heart Association defines a child for CPR purposes as anyone from age one to the onset of puberty, roughly 12 to 14 years old, recognized by chest or underarm hair development in males and breast development in females. Once puberty is evident, adult CPR ratios and depths apply. Below age one, infant cpr techniques take over with two fingers or the two-thumb encircling hands technique and special airway considerations.
This guide walks you through every dimension of the pediatric CPR ratio: compression depth, rate, hand placement, breath volume, AED pad selection, and how the algorithm changes when help arrives. We will also explore how the ratio fits into the broader chain of survival, from early recognition and activation of emergency response through advanced life support handoff in the emergency department or pediatric intensive care unit.
If you have never performed CPR on a child, the idea can feel terrifying. The good news is that the steps are simple, repeatable, and forgiving. Pushing too hard is far better than not pushing at all, and any compression is better than none. Bystander CPR doubles or triples the chance of survival, and the longer it takes to start, the lower the odds of a meaningful recovery. Hesitation is the real enemy.
By the end of this guide, you will know exactly when to use 30:2 versus 15:2, how to coordinate breaths with compressions, what to do if you are alone versus part of a team, and how to integrate an AED into your response. You will also understand how the cpr ratio for child connects to pals certification, BLS provider courses, and the broader pediatric advanced life support framework used in hospitals and ambulances every day.
Whether you are a parent learning the basics, a daycare worker renewing certification, a school nurse refreshing protocols, or a paramedic preparing for recertification, this resource gives you the depth and detail you need. Bookmark it, share it with colleagues, and pair it with hands-on practice to build the muscle memory that turns knowledge into life-saving action when seconds count.
Confirm the area is safe from traffic, water, electrical hazards, or fire. Tap the child's shoulder and shout loudly to check responsiveness. If unresponsive, prepare to act immediately and assign someone to call 911.
If alone with a witnessed sudden collapse, call 911 first. If unwitnessed arrest or suspected respiratory cause, give 2 minutes of CPR before calling. Send a bystander for an AED while you continue care.
Scan for normal breathing and check the brachial or carotid pulse for no more than 10 seconds. Agonal gasps are not normal breathing. If pulse is absent or under 60 with poor perfusion, begin compressions.
Place the heel of one or two hands on the lower half of the sternum. Compress at least 2 inches deep, 100-120 per minute, allowing full chest recoil. Minimize interruptions to maintain perfusion pressure.
After 30 compressions, open the airway with head-tilt chin-lift and give 2 breaths over 1 second each. Watch for visible chest rise. Avoid excessive ventilation, which reduces venous return and worsens outcomes.
Use pediatric pads or attenuator if under 8 years old. Follow voice prompts, deliver shocks if advised, and resume compressions immediately. Continue cycles until EMS arrives or the child shows signs of life.
The 30:2 versus 15:2 distinction is the single most tested concept in pediatric CPR courses and the national cpr foundation curriculum. For lone rescuers without advanced training, 30 compressions followed by 2 breaths keeps the sequence simple and consistent across age groups, reducing cognitive load during a crisis. The same ratio applies whether you are working on a toddler, school-aged child, or adult, which is why the AHA standardized this number for single-rescuer scenarios across all age categories.
When two or more trained providers are present, the ratio drops to 15:2 for children and infants. This change reflects the pediatric pathophysiology of arrest. Because most pediatric arrests stem from respiratory failure, doubling the frequency of ventilations restores oxygenation faster while still maintaining adequate coronary and cerebral perfusion through near-continuous compressions delivered by a partner who can pause briefly for breaths.
The transition from 30:2 to 15:2 should happen the moment a second trained rescuer arrives and is ready to assist with ventilations using a bag-valve-mask or pocket mask. Communicate clearly: announce "switching to 15:2" so both providers stay synchronized. Switch compressor roles every two minutes to prevent fatigue, which is the leading cause of shallow, ineffective compressions that drop survival rates significantly.
Each cycle of 15 compressions should take roughly 9 to 10 seconds at a rate of 100 to 120 per minute. The two breaths that follow should each take about one second, delivered with just enough volume to make the chest visibly rise. Over-ventilation is a common error that increases intrathoracic pressure, reduces venous return to the heart, and lowers cardiac output during the very moments you are trying to restore it.
An advanced airway changes the rhythm entirely. Once an endotracheal tube, supraglottic airway, or i-gel device is in place, compressions become continuous at 100 to 120 per minute, and breaths are delivered asynchronously at one breath every 2 to 3 seconds, or roughly 20 to 30 breaths per minute. This represents a faster respiratory rate than older guidelines recommended and reflects evidence that pediatric patients benefit from more aggressive ventilation support.
Knowing when to apply which ratio comes from practice, not memorization alone. Manikin training during pals certification courses, simulation labs, and team-based code drills help providers internalize the timing so it becomes automatic. When real arrest happens, no one has time to think through ratios, depths, or rates. The muscle memory must already be there, ready to deploy without conscious effort.
Lay rescuers should not stress about switching ratios. Sticking with 30:2 throughout the entire resuscitation is perfectly acceptable and avoids confusion. What matters most is starting CPR fast, pushing hard and fast in the center of the chest, and continuing without interruption until professional help arrives with the equipment and training to take over advanced interventions.
Compress at least one-third the depth of the chest, which is approximately 2 inches or 5 centimeters for most children. Going too shallow fails to generate adequate cardiac output, while excessive depth risks rib fractures, pneumothorax, or liver lacerations. Pediatric chests are more compliant than adults, so depth feedback devices on modern AEDs can help confirm you are reaching the target without overshooting.
Full chest recoil between compressions is just as critical as depth. Leaning on the chest between pushes prevents the heart from refilling with blood, dramatically reducing the effectiveness of each subsequent compression. Lift your hands slightly without losing contact, allowing the chest wall to spring back fully before pressing down again. This technique sustains coronary perfusion pressure throughout the resuscitation.
The target compression rate is 100 to 120 per minute for children, infants, and adults alike. Songs like Stayin' Alive by the Bee Gees, Crazy in Love by Beyoncé, or Baby Shark all match this tempo and can help rescuers maintain the proper cadence during real emergencies. Faster than 120 reduces depth quality, while slower than 100 fails to circulate enough blood.
Modern feedback devices, smartphone metronome apps, and AED voice prompts can guide rate in real time. Studies show that audio-visual feedback during resuscitation improves compression quality and short-term survival outcomes. If you have access to any feedback tool, use it. Otherwise, count out loud and stay disciplined about the tempo throughout each two-minute cycle.
For children, place the heel of one hand on the lower half of the sternum, just below the nipple line. Smaller children may require only one hand, while larger children approaching puberty often need two hands stacked, as you would for an adult. Keep your fingers off the ribs and your shoulders directly over the chest to use body weight rather than arm strength.
For infants under one year, use the two-finger technique if alone or the two-thumb encircling hands method if two rescuers are present. The two-thumb method generates higher arterial pressures and is preferred during infant cpr by trained providers. Compress the lower half of the sternum just below the imaginary line connecting the nipples, avoiding the xiphoid process.
Bystander CPR doubles or triples the chance of a child surviving cardiac arrest with intact neurologic function. Brain cells begin dying within 4 to 6 minutes without circulation. Starting compressions immediately, even imperfectly, is far better than waiting for trained help. Do not let fear of doing it wrong stop you from saving a life.
Automated external defibrillator use in children requires special consideration that every rescuer should understand before the moment of crisis arrives. So what does aed stand for? AED stands for automated external defibrillator, a portable device that analyzes heart rhythm and delivers a measured electrical shock if a shockable rhythm like ventricular fibrillation or pulseless ventricular tachycardia is detected. While pediatric arrest is more often non-shockable, having an AED ready can still save lives when shockable rhythms occur.
For children under 8 years old or weighing less than 55 pounds, use pediatric pads or activate the pediatric attenuator key that reduces the energy dose from the adult setting of 150 to 200 joules down to roughly 50 to 75 joules. If pediatric pads or an attenuator are unavailable, use adult pads rather than withholding defibrillation entirely. A potentially life-saving shock at full dose is better than no shock at all when the rhythm is shockable.
Pad placement for small children should follow the anterior-posterior position, with one pad on the center of the chest and one on the upper back between the shoulder blades. This prevents the two pads from touching each other on a small chest, which would short-circuit the current and waste the shock. For larger children, standard anterior-lateral placement on the upper right chest and lower left side works just as it does for adults.
The AED voice prompts will guide you through every step, including when to stand clear, when to deliver the shock, and when to resume CPR. Trust the device. It will not advise a shock unless a shockable rhythm is present, so you cannot accidentally harm a child by attaching it. Modern AEDs are designed for use by completely untrained bystanders and have been deployed successfully in schools, airports, gyms, and shopping centers worldwide.
Recovery position is rarely used during active resuscitation, but the position recovery becomes important once a child regains a pulse and is breathing adequately on their own. Place them on their side with the lower arm extended forward, upper leg bent for stability, and head tilted slightly back to keep the airway open. This prevents aspiration of vomit and maintains airway patency while you wait for EMS to transport.
Special situations like drowning, electrocution, trauma, or drug overdose alter the standard approach. Drowning victims benefit from immediate rescue breaths before compressions due to the hypoxic mechanism. Trauma patients require cervical spine protection during airway management. Electrocution victims may need prolonged resuscitation as the heart can sometimes restart after extended downtime. Knowing these nuances comes from formal training, not internet articles alone.
Family presence during resuscitation has become standard practice in many emergency departments and pediatric intensive care units. Allowing parents to witness the resuscitation, when a dedicated support person can guide them, helps closure regardless of outcome. As a lay rescuer, you may be performing CPR with the child's parents watching. Stay focused, communicate calmly, and remember that your actions are giving their child the best possible chance at life support and survival.
Formal certification transforms knowledge into confident action. The most common pediatric-focused course is pals certification, also known as Pediatric Advanced Life Support, offered by the American Heart Association. PALS builds on Basic Life Support skills and adds advanced airway management, IV and intraosseous access, rhythm recognition, medication dosing by weight, and team-based code management. It is required for pediatric nurses, emergency physicians, paramedics, and many pediatric hospital staff.
For lay rescuers, parents, teachers, and coaches, a Heartsaver CPR AED course covering adult, child, and infant resuscitation is the ideal starting point. These four-hour courses include hands-on manikin practice with instructor feedback, choking management, AED operation, and the differences between age groups. Most are available in person through community centers, hospitals, fire departments, and online with skills check-offs at local testing sites.
Healthcare providers typically need BLS for Healthcare Providers certification, which goes deeper into two-rescuer CPR, bag-valve-mask ventilation, pulse checks, and team dynamics. BLS is the foundation for ACLS and PALS and must be renewed every two years. The acls algorithm framework for adults parallels the PALS algorithm for children, with both emphasizing high-quality CPR, rhythm-based interventions, and reversible cause identification using the H's and T's mnemonic.
Online-only certifications without hands-on skills verification are not accepted by hospitals, employers, or licensing boards in most cases. Always verify that any course you take meets your employer's requirements before paying. Look for AHA, American Red Cross, ASHI, or other accredited providers with verifiable certification cards that include unique identifiers, expiration dates, and QR codes for instant verification by employers.
Recertification typically occurs every two years for BLS, PALS, and ACLS. Some employers require annual skills refreshers or mock code participation between formal renewals. Many providers find that frequent low-stakes practice through code simulations, manikin sessions, and online refresher modules maintains skills far better than waiting for the two-year cycle to come around again.
Beyond formal courses, family-focused programs like Friends and Family CPR teach the basics without offering a certification card. These shorter sessions are perfect for new parents, grandparents, babysitters, and anyone who interacts regularly with children. The information taught is the same evidence-based content from full certification courses, just delivered without the testing and credentialing component.
Whichever path you choose, the most important step is taking action. Sign up for a course this month. Practice hands-on at least once per year. Talk through scenarios with family members and coworkers. Keep AEDs and pocket masks accessible at home, in your car, and at your workplace. The cpr ratio for child is simple to memorize, but applying it under pressure requires preparation that only comes from training and repetition.
Practical preparation transforms abstract knowledge into life-saving reflexes. Start by walking through your home, workplace, and child's school to identify the nearest AED locations. Many states now require AEDs in schools, gyms, and public buildings. Download the PulsePoint AED app or similar registries that map AED locations near you. Knowing where to send a bystander to retrieve one shaves precious seconds off the response time during a real emergency.
Build a small home emergency kit that includes a pocket mask with one-way valve, disposable gloves, a flashlight, and a printed CPR reference card sized for your refrigerator or wallet. The pocket mask eliminates direct mouth-to-mouth contact, addressing the hygiene concern that causes many bystanders to skip rescue breaths. Practice opening and assembling your mask at least twice per year so you can deploy it without fumbling under stress.
Teach the basics to every family member who is old enough to learn, typically by age 9 or 10. Children can learn to call 911, push hard and fast in the center of the chest, and follow AED voice prompts. Some of the most heartwarming survival stories involve children performing CPR on parents or grandparents. Empowering kids with this knowledge builds confidence and removes the panic that paralyzes adults during emergencies.
Coordinate with your child's school, sports league, and daycare to verify their CPR and AED protocols. Ask whether staff are certified, when they last renewed, where the AED is located, and what their cardiac emergency response plan looks like. If gaps exist, advocate for training and equipment. Many insurance plans, workplace wellness programs, and community foundations subsidize CPR training costs for parents and caregivers.
Mental rehearsal is a surprisingly powerful preparation tool used by elite athletes, military personnel, and emergency responders. Spend five minutes visualizing yourself responding to a child collapse at the park, in your home, or at a family gathering. Walk through the steps: check safety, check responsiveness, call 911, send for AED, start compressions. Mental rehearsal primes your brain to act rather than freeze when reality strikes.
Stay current with guideline updates. The American Heart Association releases major guideline revisions roughly every five years, with focused updates between cycles. Subscribe to the AHA's email list or follow trusted medical education channels to learn about changes that affect your skills. Recent updates have refined respiratory rate recommendations, defibrillation energy doses, and post-resuscitation care protocols based on emerging research.
Finally, take care of yourself emotionally if you ever do perform CPR. Even successful resuscitations are traumatic to witness and participate in. Survivors of pediatric arrest sometimes have lasting deficits, and not all victims survive. Critical incident stress debriefings, employee assistance programs, peer support groups, and licensed therapists can help you process the experience. Your willingness to act made a difference, regardless of outcome, and that courage deserves recognition and support.
