CPR (Cardiopulmonary Resuscitation) Practice Test

โ–ถ

Pediatric CPR is a specialized lifesaving skill that every parent, caregiver, teacher, coach, and healthcare provider should master because children are not just small adults. Their airways are narrower, their bones more pliable, and their physiology responds differently to cardiac emergencies than adults do. Roughly 7,000 children experience out-of-hospital cardiac arrest in the United States each year, and survival rates climb dramatically when a bystander begins compressions before EMS arrives. This guide walks you through the complete 2026 protocols for infants under one year and children up to puberty.

Unlike adult arrest, which usually stems from a primary cardiac event, pediatric arrest is most often secondary to respiratory failure, drowning, choking, or trauma. That distinction matters because it shapes the entire resuscitation approach. The American Heart Association emphasizes high-quality ventilations alongside compressions for pediatric victims, and understanding the difference between primary cardiac and respiratory causes helps you understand heart attack vs cardiac arrest in the context of pediatric patients.

The compression depth, hand placement, ventilation rate, and compression-to-ventilation ratio all change depending on whether you are working on an infant, a child, or an adolescent who has reached puberty. Getting these details right can be the difference between a meaningful neurological recovery and a tragic outcome. Pediatric CPR also requires you to remain calm enough to communicate with terrified parents while you work, which is an emotional skill rarely taught in standard courses.

This article covers everything from initial scene assessment through advanced life support handoff. You will learn the two-finger and two-thumb encircling techniques for infant compressions, the one-hand versus two-hand methods for children, when to use an AED with pediatric pads, how to recognize agonal breathing, and how to integrate the acls algorithm when shockable rhythms appear. We also cover the recovery position, choking response, and post-resuscitation care.

Whether you are pursuing pals certification, refreshing skills before a babysitting job, or preparing for a clinical rotation, the information here matches current AHA, Red Cross, and national cpr foundation guidelines. We have included real numbers, common mistakes, and the latest 2026 protocol updates that emerged after the most recent ILCOR evidence review. Each section builds on the last, so even readers with no medical background can follow along.

Pediatric arrest is rare in everyday life, which is precisely why preparation matters. Most people who perform pediatric CPR will do it once in their lifetime, often on a child they love. The minutes between collapse and ambulance arrival are the ones that determine outcome, and those minutes belong entirely to the bystander. The goal of this guide is to make you that confident, competent bystander who knows exactly what to do.

By the end of this article you will understand age-based technique differences, AED considerations, two-rescuer dynamics, and the emotional dimension of pediatric resuscitation. You will also have access to free practice quizzes that mirror the questions on actual certification exams, so you can test your knowledge before walking into a classroom or clinical setting.

Age Categories and Technique Differences

๐Ÿ‘ถ Infants (Under 1 Year)

For infants, use two fingers just below the nipple line for single rescuer, or the two-thumb encircling technique for two rescuers. Compression depth is 1.5 inches, about one-third the chest depth. Cover both nose and mouth for ventilations.

๐Ÿง’ Children (1 Year to Puberty)

Use one or two hands on the lower half of the sternum, whichever achieves 2-inch compression depth. Pinch the nose and seal the mouth for rescue breaths. Avoid hyperextending the neck on small children with floppy airways.

๐Ÿง‘ Adolescents (Post-Puberty)

Treat as adults: two hands stacked on the lower sternum, 2 to 2.4 inches deep, 30:2 ratio regardless of rescuer count. Signs of puberty include breast development in girls and underarm hair in boys, not strict age cutoffs.

๐Ÿผ Newborns (First 28 Days)

Neonatal resuscitation uses a 3:1 compression-to-ventilation ratio with 90 compressions and 30 breaths per minute. This is a distinct protocol from infant CPR and is taught in NRP rather than standard pediatric BLS courses.

Compressions are the engine of any resuscitation, and pediatric compressions demand precision because the margin for error is so small. For infants, place two fingers on the breastbone just below an imaginary line connecting the nipples and press straight down approximately 1.5 inches, or about one-third the depth of the chest. The two-thumb encircling technique, used by two trained rescuers, generates higher coronary perfusion pressure and is now the preferred method in hospital settings. Allow full chest recoil between every compression.

For children between one year and puberty, place the heel of one hand on the lower half of the sternum. If the child is large or you are smaller, use two hands stacked as you would on an adult. The target depth is 2 inches, again about one-third the chest depth, never exceeding 2.4 inches. Compression rate stays at 100 to 120 per minute for every age group, matching the cadence of the song Stayin Alive. Maintaining this rate while delivering effective breaths is harder than it sounds.

Ventilations are uniquely critical in pediatric arrest because most events are caused by hypoxia. For infants, seal your mouth over both their nose and mouth and deliver a gentle puff just large enough to make the chest visibly rise, about one second per breath. For children, pinch the nose and form a tight seal over the mouth. Overinflating causes gastric distension, which pushes against the diaphragm and worsens ventilation while increasing aspiration risk.

The compression-to-ventilation ratio shifts based on how many rescuers are present. A single rescuer uses 30:2 for all ages, mirroring adult CPR. Two rescuers switch to 15:2 for infants and children, recognizing that more frequent breaths matter when respiratory failure caused the arrest. This is one of the most tested concepts on certification exams and one of the most commonly mixed up in real emergencies. Practice it on a manikin if you can.

The respiratory rate after advanced airway placement changes again. Once an endotracheal tube or supraglottic airway is in place, compressions become continuous and ventilations are delivered asynchronously at one breath every 2 to 3 seconds, which equals 20 to 30 breaths per minute. This 2026 update from AHA replaced the older 6-second interval to better match physiologic needs. Track the rate with a metronome or timer to avoid hyperventilation, which reduces cerebral blood flow.

Recoil is the silent killer of pediatric CPR quality. Rescuers tense their arms and lean on the chest between compressions, preventing the heart from refilling. This drops cardiac output by as much as 25 percent. Lift your palms slightly off the chest at the top of each upstroke without losing hand position. Many manikins now provide real-time feedback on recoil, and even pocket-sized CPR coaches can keep your technique honest during a real arrest.

Switching compressors every two minutes maintains quality because fatigue degrades depth and rate within just 90 seconds, even though rescuers rarely feel tired. If you are alone, you cannot switch, so focus on maintaining tempo and depth as long as possible. Resources like baby cpr hybrid courses now offer at-home manikin kits that build the muscle memory needed for sustained, high-quality compressions.

AED Use and the ACLS Algorithm in Pediatrics

๐Ÿ“‹ AED Application

The acls algorithm guides advanced providers, but the AED is the bystander's most powerful tool. Many people ask what does aed stand for: automated external defibrillator. For children 1 to 8 years or under 55 pounds, use pediatric pads with a dose attenuator that reduces energy delivery. If pediatric pads are unavailable, adult pads are acceptable and recommended over withholding shocks, but place one pad on the chest and the other on the back to prevent overlap.

For infants under one year, a manual defibrillator operated by a trained provider is preferred. If only an AED is available, use one with a pediatric attenuator. Never delay defibrillation searching for the perfect device. The chance of survival drops 7 to 10 percent for every minute defibrillation is delayed in a shockable rhythm. Turn the AED on, follow the voice prompts, and resume compressions immediately after each shock or no-shock advisory.

๐Ÿ“‹ Shockable Rhythms

Pediatric arrests are less often shockable than adult ones, but ventricular fibrillation and pulseless ventricular tachycardia still account for about 10 to 15 percent of pediatric arrests, especially those involving congenital heart conditions, electrolyte imbalances, or sudden collapse during exercise. Recognizing these rhythms requires a monitor, which is why bystanders rely on the AED to make the rhythm decision for them through automated analysis.

When a shock is indicated, the pediatric energy dose is 2 J/kg for the first shock and 4 J/kg for subsequent shocks, with a maximum that does not exceed adult doses. Bystanders never need to calculate this because the AED handles dosing automatically when pediatric pads are connected. Immediately after the shock, resume compressions for two minutes before reanalyzing, even if the rhythm appears to convert.

๐Ÿ“‹ Reversible Causes

Advanced providers running the acls algorithm search for the Hs and Ts of reversible causes during ongoing CPR. The Hs include hypoxia, hypovolemia, hydrogen ion acidosis, hypo/hyperkalemia, and hypothermia. The Ts include tension pneumothorax, tamponade, toxins, thrombosis pulmonary, and thrombosis coronary. In pediatrics, hypoxia and hypovolemia top the list because most arrests follow respiratory failure or trauma.

Treating the cause matters as much as performing CPR. A drowning victim needs oxygenation more than chest compressions alone. A child with severe asthma needs bronchodilators and airway management. Bystanders cannot treat these causes, but providing context to arriving EMS, such as how long the child was underwater or what medications they took, accelerates definitive care and improves outcomes substantially.

Single Rescuer vs Two Rescuer Pediatric CPR

Pros

  • Two rescuers can maintain higher compression quality through 2-minute switches
  • Two-thumb encircling technique generates better coronary perfusion in infants
  • One rescuer can manage airway while the other compresses
  • Faster AED application without interrupting compressions
  • Less rescuer fatigue means more consistent depth and rate
  • Ratio shifts to 15:2 allowing more frequent ventilations
  • Better real-time coaching and quality monitoring between providers

Cons

  • Single rescuer must alternate compressions and breaths alone
  • 30:2 ratio means fewer ventilations per minute when alone
  • Greater fatigue degrades quality within 90 seconds
  • Cannot effectively use bag-valve-mask without a partner
  • Difficult to call 911 and perform CPR simultaneously
  • No one to retrieve and operate the AED quickly
  • Higher cognitive load increases risk of protocol errors

Pediatric CPR Skills Checklist

Verify scene safety before approaching the child or infant
Check responsiveness by tapping shoulders or flicking foot soles on infants
Call 911 and request an AED, or send a bystander to do both
Check for breathing and a pulse for no more than 10 seconds
Begin compressions immediately if no pulse or only agonal gasps
Use correct hand placement for age: two fingers, one hand, or two hands
Compress to one-third chest depth at 100-120 per minute with full recoil
Open the airway with head-tilt chin-lift unless trauma is suspected
Deliver rescue breaths that make the chest visibly rise
Attach AED with pediatric pads as soon as it arrives and follow prompts
Hypoxia Drives Most Pediatric Arrests

Unlike adults, where sudden cardiac events dominate, more than 80 percent of pediatric arrests are secondary to respiratory failure. This means high-quality ventilations are not optional. Every effective breath that makes the chest rise can restore oxygenation faster than compressions alone, especially in drowning, choking, and asthma scenarios.

Special situations are where rote training meets reality. Choking is the most common pediatric emergency that escalates to CPR, and recognizing the difference between a mild and severe obstruction determines your response. A child who can cough forcefully, cry, or speak has a partial obstruction and needs encouragement to keep coughing. Intervening too aggressively in a mild obstruction can convert it into a complete one. Stand by, monitor closely, and call for help if the cough weakens.

A complete obstruction is silent because no air moves. The child cannot cry, cough, or speak. For children over one year, deliver up to five abdominal thrusts above the navel and below the ribcage until the object dislodges or the child becomes unresponsive. For infants, alternate five back blows between the shoulder blades with five chest thrusts using two fingers on the breastbone. Never perform abdominal thrusts on an infant because their liver position makes serious internal injury likely.

If the child becomes unresponsive during a choking episode, lower them gently to the ground and begin CPR starting with chest compressions. Before each set of ventilations, look inside the mouth for the object and remove it only if visible. Never perform a blind finger sweep because you can push the obstruction deeper. This sequence, sometimes called CPR with airway check, is a critical skill tested on every certification exam.

Drowning is another high-stakes pediatric scenario. Begin with five rescue breaths before starting compressions because the underlying problem is profound hypoxia. After the initial breaths, switch to standard 30:2 or 15:2 CPR. Continue resuscitation efforts longer than you would for an adult cardiac arrest because cold water drownings have produced remarkable neurological recoveries even after 30 minutes of submersion, particularly in young children.

Sudden infant death syndrome and apparent life-threatening events require immediate CPR even when the infant looks peaceful and pink. Do not assume the baby is sleeping. Tap the foot, call their name, and check for breathing for no more than 10 seconds. If unsure, begin CPR. Erring on the side of resuscitation has no downside, while waiting to be certain costs irreplaceable seconds.

Trauma adds layers of complexity. Maintain cervical spine stabilization with a jaw thrust rather than head-tilt chin-lift if you suspect a neck injury. Control catastrophic bleeding before compressions if blood loss caused the arrest. For penetrating chest trauma, the heart may not respond to compressions until the underlying injury is addressed, so transport priority becomes paramount. Resources like the leather cpr video library demonstrate these advanced scenarios in slow motion.

Anaphylaxis can cause pediatric arrest within minutes of exposure. If you have access to an epinephrine auto-injector and recognize the signs, use it immediately, even during CPR. Epinephrine is the only definitive treatment for anaphylactic shock, and CPR alone cannot reverse the cascading airway swelling and vascular collapse. Always carry the appropriate dose for the child's weight if they have known allergies.

Certification pathways for pediatric CPR vary depending on your role and goals. The American Heart Association offers Heartsaver Pediatric First Aid CPR AED for laypeople like babysitters, teachers, and parents. This course takes about 4 to 6 hours and provides a 2-year certification card. Healthcare providers complete BLS for Healthcare Providers, which covers adult, child, and infant CPR as well as two-rescuer techniques and bag-valve-mask ventilation. The Red Cross offers equivalent courses with the same recognition.

For advanced practitioners, pals certification is the gold standard. PALS covers systematic assessment, recognition of respiratory and circulatory failure, the acls algorithm adapted for pediatrics, vascular access, and team dynamics. The course runs 14 hours over two days and is required for pediatric emergency nurses, pediatric ICU staff, pediatricians, and emergency physicians. Recertification every two years includes a written exam and skills demonstration with megacode scenarios.

Online and hybrid options have multiplied since the pandemic, and the national cpr foundation offers fully online certification for laypeople. While convenient, purely online courses without hands-on skills verification are not recognized by most employers. Always check with your school, hospital, or workplace before enrolling to ensure the certificate will be accepted. AHA, Red Cross, and Health and Safety Institute certifications carry the broadest recognition.

Cost varies widely. Basic Heartsaver courses run $50 to $90, BLS for Healthcare Providers runs $60 to $100, and PALS runs $200 to $300. Renewal courses are typically half the price and half the time of initial certification. Some employers pay for certification as a condition of employment, and some hospitals offer free internal courses for staff. Always factor in textbook costs, which add $30 to $50 unless included.

The exam itself focuses on protocol details rather than memorization. Expect questions on compression depth by age, ratios for single versus two rescuers, AED pad placement, energy doses, and reversible causes. The questions are scenario-based, asking what you would do next given specific findings. Spending an hour with a free practice quiz before the exam catches most weak spots and builds confidence. Look for sites that offer detailed answer explanations.

Pediatric simulation training has grown rapidly and represents the future of certification. High-fidelity manikins respond to your interventions with physiologic feedback, letting you see the effect of compression depth and ventilation rate in real time. Some programs use virtual reality to simulate chaotic scenes with crying parents and distracting environments. This kind of training closes the gap between classroom skill and real-world performance, where adrenaline and emotion change everything.

Maintaining skills after certification is the hardest part. Studies show CPR proficiency degrades within 3 to 6 months without practice. Brief monthly self-refreshers using YouTube videos or pocket manikins keep skills sharp. Some hospitals require quarterly mock codes for staff. For laypeople, scheduling refresher courses every 6 to 12 months even before the 2-year renewal keeps you ready when an actual emergency demands fast, accurate action without hesitation. The cpr fix phones study guide offers month-by-month review plans.

Practical tips separate competent rescuers from heroic ones, and most of them come from real-world experience rather than textbooks. First, designate roles immediately if more than one person is present. One person performs compressions, one ventilates, one calls 911 and retrieves the AED, and one manages bystanders. Without role clarity, the scene devolves into chaos within 30 seconds. Even strangers can be assigned tasks with a calm, direct voice and pointed finger.

Second, use the floor. Performing CPR on a bed, couch, or car seat compresses the surface instead of the heart, wasting energy and reducing depth. Lower the child to the firmest available surface within arm's reach, even if that means the dirty floor of a public restroom. If they are in a car seat or stroller, remove them quickly. The few seconds spent moving the child are recovered through dramatically better compressions.

Third, talk through what you are doing. Verbalize the compression count, the breath delivery, and the AED prompts. This serves three purposes: it keeps you on tempo, it signals to bystanders that help is being given competently, and it provides clear handoff information to arriving EMS. Saying out loud the time you started CPR, how many cycles you have completed, and any rhythm analyses speeds the transition to paramedic care.

Fourth, do not stop for the parents emotional response. Parents may scream, beg, faint, or interfere. Assign a bystander to support them physically and emotionally while you keep working. If you must address them directly, brief reassurance like helping their child works better than long explanations. Stopping compressions to talk costs lives, and parents universally support your full focus on the child once they later understand why.

Fifth, prepare your environment in advance. Know where the nearest AED is at your school, workplace, gym, or place of worship. Pediatric AED pads should be stocked alongside adult pads in any facility serving children. Verify pad expiration dates twice a year, and ensure battery indicators show green. The AED that saves your child's life is the one whose location and condition you confirmed before the emergency happened.

Sixth, integrate the recovery position into your training. After successful resuscitation, a breathing but unresponsive child should be rolled onto their side with the upper leg bent forward to stabilize them. This position prevents aspiration if they vomit, which is common after cardiac events. Monitor breathing continuously and be ready to flip them back and resume CPR if their condition deteriorates before EMS arrives.

Finally, debrief afterward. Pediatric resuscitations, even successful ones, leave rescuers traumatized. Talk with friends, family, or a counselor about what happened. Many hospitals offer critical incident stress debriefings for staff after pediatric arrests, and similar resources exist for laypeople through Red Cross peer support. The emotional impact is real and lasting, but processing it with support transforms a traumatic memory into the foundation of confidence for future emergencies you may face.

CPR Questions and Answers

What is the correct compression depth for infant CPR?

For infants under one year, compress the chest approximately 1.5 inches deep, or about one-third the depth of the chest. Use two fingers just below the nipple line for a single rescuer, or the two-thumb encircling technique with both thumbs side by side on the sternum if two trained rescuers are available. Allow full chest recoil between compressions and maintain a rate of 100 to 120 compressions per minute.

What is the compression-to-ventilation ratio for pediatric CPR?

A single rescuer uses 30 compressions to 2 ventilations for both infants and children, identical to adult CPR. When two trained rescuers are present, the ratio shifts to 15 compressions to 2 ventilations for pediatric patients to deliver more frequent breaths, since most pediatric arrests are caused by respiratory failure. After an advanced airway is placed, compressions become continuous with a breath every 2 to 3 seconds.

Can you use an adult AED on a child or infant?

Yes, when pediatric pads or a pediatric attenuator are unavailable, adult AED pads can be used on children and infants because any defibrillation is better than no defibrillation. Place one pad on the front of the chest and the other on the back to prevent the pads from touching each other on a small body. Always use pediatric pads when available for children under 8 years or 55 pounds.

How do you check a pulse on an infant during CPR?

Check the brachial pulse on an infant by placing two fingers on the inside of the upper arm between the shoulder and elbow, pressing gently. Spend no more than 10 seconds checking. If you cannot definitely feel a pulse or if the heart rate is below 60 with signs of poor perfusion, begin chest compressions. The carotid pulse used in adults and older children is too difficult to locate on a small infant neck.

What does the acls algorithm cover in pediatric arrest?

The acls algorithm in pediatric form, called PALS, covers systematic assessment, high-quality CPR, rhythm recognition, defibrillation timing and energy dosing, vascular access, medication administration including epinephrine and amiodarone, advanced airway management, and identification of reversible causes summarized as the Hs and Ts. It also emphasizes team dynamics, closed-loop communication, and post-resuscitation care during the critical hours after return of spontaneous circulation.

Should I do mouth-to-mouth on a stranger's child during an emergency?

Yes, if you are trained and willing, rescue breaths significantly improve survival in pediatric arrests because most are caused by respiratory failure rather than primary cardiac events. Compression-only CPR is acceptable if you are untrained, uncomfortable, or concerned about disease transmission, but adding breaths is preferable when possible. Pocket masks or face shields are inexpensive barriers that make rescue breathing safer and are easy to carry on a keychain.

How is infant cpr different from child or adult CPR?

Infant cpr differs in hand placement using two fingers or two-thumb encircling rather than palms, compression depth of 1.5 inches versus 2 inches in children, ventilation technique covering both nose and mouth, and pulse check location at the brachial artery. The compression rate of 100 to 120 per minute and the 30:2 single-rescuer ratio remain the same. Two-rescuer ratio shifts to 15:2 for both infants and children, unlike adults who stay at 30:2.

How long should pediatric CPR continue before stopping?

Continue pediatric CPR until trained EMS providers take over, the child shows signs of life such as breathing or movement, you become physically unable to continue, or scene safety becomes compromised. For drowning, hypothermia, or toxic exposures, continue significantly longer than typical adult arrests because pediatric patients have shown remarkable recoveries after 30 or more minutes of resuscitation in cold water scenarios. Never stop because the situation feels hopeless; the decision belongs to medical professionals.

What is the recovery position for children after CPR?

After successful resuscitation, place a breathing but unresponsive child on their side with the lower arm extended forward, the upper leg bent at the knee for stability, and the head tilted slightly back to maintain an open airway. This position recovery prevents aspiration if vomiting occurs, which is common after cardiac events. Continuously monitor breathing and pulse, and be prepared to roll them back and resume CPR immediately if their condition deteriorates.

How do I get pals certification and how long does it last?

To earn pals certification, complete a 14-hour Pediatric Advanced Life Support course offered by the American Heart Association, Red Cross, or equivalent training organizations. The course includes online preparation, in-person skills practice, megacode scenarios, and a written exam scoring 84 percent or higher. Certification lasts 2 years, after which you must complete a shorter renewal course with skills verification. The certification is required for pediatric emergency room nurses, pediatric ICU staff, and emergency physicians.
