Knowing the 6 CPR steps can mean the difference between life and death when cardiac arrest strikes. Cardiopulmonary resuscitation, or CPR, is an emergency life-saving procedure that combines chest compressions and rescue breaths to manually keep oxygenated blood circulating when the heart stops beating on its own. Studies consistently show that immediate bystander CPR can double or even triple a cardiac arrest victim's chance of survival, yet fewer than half of cardiac arrest victims outside a hospital receive this critical intervention from a bystander before emergency services arrive.

The 6 cpr steps framework was developed by the American Heart Association and adopted by organizations like the National CPR Foundation to give rescuers a clear, memorable sequence to follow under pressure. When someone collapses and stops breathing normally, panic is the enemy — and a practiced sequence of steps is your best weapon against it. Whether you are pursuing PALS certification, studying the ACLS algorithm, or simply want to be prepared as a bystander, understanding each step in depth allows you to act confidently and correctly in a real emergency.

This guide walks you through every phase of CPR, from recognizing that a person needs help to positioning them in the recovery position after spontaneous circulation returns. We cover how the steps differ for adults, children, and infant CPR scenarios, what an AED is and exactly when to use one, and how to adjust your respiratory rate and compression depth for different victims. By the end, you will have a thorough understanding of what the steps require and why each one is sequenced the way it is.

It is worth noting that CPR proficiency is not just for healthcare professionals. Laypersons who complete even a brief certification course are far more equipped to help in an emergency than those with no training at all. Organizations from the National CPR Foundation to the Red Cross offer blended online and hands-on courses, and many employers now require documented life support training for certain roles. If you want to understand 6 steps for cpr certification timelines and renewal cycles, there are excellent resources on this site to guide you.

One common misconception is that CPR is too complicated for untrained bystanders. In reality, the core of modern CPR — particularly Hands-Only CPR endorsed by the AHA for adult victims — requires just two components: calling 911 and pushing hard and fast on the center of the chest. However, for trained rescuers, infants, children, and drowning victims, the complete six-step sequence that includes rescue breaths is significantly more effective and remains the standard taught in formal certification programs.

Throughout this article, we reference key terms you may encounter in your studies or on the job, including what does AED stand for (Automated External Defibrillator), how to use it, the correct respiratory rate for rescue breathing, and how the ACLS algorithm integrates CPR into a broader cardiac arrest response. Whether you are preparing for a certification exam or refreshing your knowledge ahead of a recertification, this guide provides the depth and accuracy you need to feel truly prepared.

Emergency cardiovascular care guidelines are updated every five years by the AHA based on the latest evidence. The current standards emphasize high-quality chest compressions above all else — the right depth, the right rate, minimal interruptions, and allowing full chest recoil between compressions. These principles underpin every step described in this guide, ensuring that the care you provide is both safe and maximally effective for the person who needs it most.

Understanding what happens inside the body during each of the 6 CPR steps helps you perform them correctly and with purpose. Cardiac arrest occurs when the heart's electrical system malfunctions, causing the heart to stop pumping blood effectively. Within 4 to 6 minutes of no circulation, the brain begins sustaining irreversible damage from oxygen deprivation. Chest compressions are designed to physically squeeze the heart between the sternum and the spine, forcing blood out to the brain and vital organs with each compression cycle.

The compression-to-ventilation ratio most commonly taught today is 30 compressions to 2 rescue breaths for a single rescuer responding to a victim of any age except newborns. This ratio reflects decades of research showing that excessive interruptions for ventilation reduce the average blood flow generated during CPR. For two-rescuer scenarios — the standard in professional settings and tested by the ACLS algorithm — one rescuer compresses while the other manages the airway, and they switch roles every two minutes to prevent fatigue-related quality decline.

Proper hand placement is one of the most frequently misunderstood elements of the compression step. Many untrained bystanders place their hands too high (near the collar bones) or too far to one side. The correct position is the center of the chest on the lower half of the breastbone.

For adults, compressions should reach a depth of at least 2 inches but not exceed 2.4 inches. Going too shallow means inadequate perfusion pressure; going too deep risks rib fractures and internal injury, though rib fractures during CPR are a known and generally acceptable complication in adults when the alternative is death.

Allowing full chest recoil between compressions is equally important and often overlooked. When you lean on the chest between compressions, you prevent the heart from refilling with blood, reducing the output of each subsequent compression. Lift the heel of your hand slightly after each downstroke to allow the chest to fully return to its neutral position.

This creates the negative pressure that draws venous blood back into the heart chambers, setting up the next effective compression. Even experienced providers tend to degrade in compression quality after one to two minutes, which is why the AHA recommends switching compressors every two minutes.

Rescue breaths, when delivered correctly, contribute significantly to survival outcomes in children, drowning victims, and victims of respiratory arrest. Each rescue breath should be delivered over 1 second and produce visible chest rise — no more, no less. Over-ventilating is a common error that increases intrathoracic pressure, reduces venous return, and can push air into the stomach, causing regurgitation. The correct respiratory rate for rescue breathing in CPR is 10 to 12 breaths per minute when performed with an advanced airway in place, or 2 breaths every 30 compressions without one.

If you are uncomfortable performing mouth-to-mouth ventilation, Hands-Only CPR — continuous chest compressions without rescue breaths — is endorsed by the AHA for adult victims of sudden cardiac arrest who collapse in front of you. Studies show that the oxygen already in the bloodstream at the time of arrest is sufficient to sustain some brain and organ function for several minutes when compressions are performed effectively. However, Hands-Only CPR is not recommended for children, infants, drowning victims, or victims of drug overdose, as these populations commonly arrest due to respiratory failure first, and ventilation is therefore essential to their resuscitation.

For those who are committed to learning the full six-step process and want to deepen their understanding through structured practice, the curriculum covered in formal certification programs from the National CPR Foundation and the American Heart Association includes hands-on mannequin practice, AED simulation, and scenario-based learning. These experiences are critical for building the muscle memory that allows you to perform compressions at the correct rate, depth, and with proper recoil — skills that are difficult to internalize from reading alone but become automatic with repetition.

Infant CPR is one of the most important — and most distinct — variations of the standard 6-step sequence. The anatomy and physiology of infants differ significantly from adults, which requires meaningful changes in technique at almost every step. Recognizing these differences before an emergency occurs is critical, because the high-stress nature of a pediatric cardiac arrest makes it even harder to recall and apply information you have not thoroughly internalized beforehand. Infant CPR is tested on PALS certification exams and is covered in most standard BLS courses as well.

For infants (defined as children under 1 year of age), scene safety and responsiveness checks remain the same as for adults. However, to check responsiveness in an infant, you flick or tap the bottom of the foot rather than tapping the shoulders. Infants cannot respond verbally, so you are watching for movement, crying, or a physical reaction. If there is no response and normal breathing is absent, activate emergency services immediately by calling 911, or directing someone nearby to call while you begin resuscitation.

Opening the airway in an infant requires a neutral head position rather than the extended head-tilt used for adults. Extending an infant's neck too far can actually occlude the airway due to the relative softness of tracheal cartilage in very young patients. Place the infant on a flat surface and gently tilt the head back to a neutral or slightly extended position, lifting the chin with two fingers. Be careful not to compress the soft tissue under the chin, which can close off the airway.

Infant rescue breathing uses smaller volumes delivered more gently than adult ventilations. Many rescuers use the mouth-to-mouth-and-nose technique, sealing both the infant's mouth and nose simultaneously with their own mouth and delivering puffs of air — enough to see the chest rise visibly but not forcefully. The respiratory rate for infant rescue breathing in CPR follows the same 30:2 ratio for a single rescuer, or 15:2 for two-rescuer healthcare provider CPR on pediatric victims, reflecting the higher importance of ventilation in pediatric arrest etiology.

Chest compressions for infants use just two fingers placed on the center of the breastbone, just below the nipple line. The target compression depth is at least 1.5 inches — approximately one-third of the anterior-posterior diameter of the chest. The rate remains 100–120 compressions per minute, the same as for adults. For two healthcare providers managing an infant, the preferred technique is the two-thumb encircling hands method: both thumbs are placed on the lower third of the sternum while the fingers encircle the thorax, which generates higher coronary perfusion pressure than the two-finger method.

Child CPR — for victims aged 1 year through puberty — uses a transitional technique. Compressions are delivered with one or two hands depending on the child's size, at a depth of at least 2 inches (about one-third of the chest's depth). Rescue breaths follow the same 30:2 ratio for single rescuers and 15:2 for two-rescuer healthcare providers. AED use in children requires pediatric-specific pads or an attenuator that reduces the energy output to age-appropriate levels; however, if pediatric pads are unavailable, adult pads may be used on a child over 8 years old.

The National CPR Foundation and the American Heart Association both emphasize that knowing the differences in technique between adult, child, and infant CPR is essential not just for passing a certification exam but for providing the right care in a real emergency. Pediatric cardiac arrest is far more commonly caused by respiratory failure than by primary cardiac causes, which is why rescue breaths are never optional for children and infants — even for bystanders who might otherwise choose Hands-Only CPR for an adult victim.

After a victim regains spontaneous circulation — meaning the heart restarts on its own — the appropriate next step is placing them in the recovery position while awaiting EMS arrival. The recovery position prevents aspiration in a breathing but unconscious person by using gravity to keep the airway clear. Gently roll the victim onto their side, support the head, bend the top knee forward to stabilize the body, and ensure the mouth is angled slightly downward. Monitor breathing continuously and be prepared to resume CPR if circulation is lost again.

The recovery position (also called the lateral recumbent position) should not be used if you suspect a spinal injury — for example, after a fall from height or a vehicle collision. In those cases, maintain the victim in the position found and focus on airway maintenance without rotating the spine. EMS providers carry cervical collars and log-roll protocols that allow for safe repositioning under those circumstances. In most non-trauma cardiac arrest situations, however, the recovery position is the correct management for a victim who is breathing adequately after resuscitation.

One frequently searched topic in the CPR space is "cpr cell phone repair" and "cpr phone repair" — referring to the national franchise chain CPR Cell Phone Repair, which is entirely unrelated to cardiopulmonary resuscitation. If you arrived here looking for device repair services, you will want to search specifically for CPR Cell Phone Repair locations in your area. If you are here for cardiac resuscitation training, you are in the right place — and we encourage you to explore the full range of practice quizzes and certification resources on PracticeTestGeeks.com to solidify your knowledge.

After EMS arrives and takes over care, your role as a bystander rescuer is complete. Do not feel pressure to continue managing the scene; trained paramedics will assume care and transport the victim to a hospital. However, make yourself available to provide information to responding crews: how long the victim was down before CPR was started, how many shocks the AED delivered, and whether the victim showed any signs of life at any point. This handoff information is clinically valuable and helps EMS providers make faster, better-informed decisions about ongoing care and destination hospital selection.

From a certification and training perspective, the recovery position and post-resuscitation management are covered in both BLS for Healthcare Providers courses and in Heartsaver CPR AED courses designed for the general public. Understanding what to do after successful resuscitation — including monitoring breathing, maintaining position, communicating with EMS, and managing bystanders at the scene — rounds out a truly complete picture of emergency cardiac care that goes beyond the compression-and-breath cycle itself.

CPR skills decay significantly within three to six months without practice, which is why the AHA recommends skills practice at least annually even within the standard two-year certification window. Many organizations and workplaces invest in CPR practice kiosks, tabletop mannequins, or refresher microlearning modules to keep skill retention high between formal recertifications. If you want to stay sharp, the practice quizzes and study tools on this site are an excellent complement to physical mannequin practice, allowing you to keep the cognitive knowledge of CPR protocols fresh between hands-on sessions.

For those pursuing formal credentials, it is important to track your certification expiration date carefully. Most BLS, ACLS, and PALS certifications are valid for two years from the date of issuance, and many employers require renewal well before the expiration date to avoid a lapse in credentialed status. If you are unsure about your renewal timeline, understanding the nuances of how long CPR credentials remain valid is essential planning information for any healthcare professional or trained layperson who relies on their certification for employment or volunteer work.

Preparing for a CPR certification exam — whether for BLS, Heartsaver, ACLS, or PALS certification — requires both cognitive knowledge and physical skill. The written or online knowledge assessment typically covers the steps of CPR, compression rate and depth, ventilation ratios, AED use, recognition of cardiac arrest, and special populations including infant CPR. Understanding why each guideline exists, not just what the guideline says, significantly improves both test performance and real-world application under stress.

One of the most effective study strategies for CPR exams is active recall — testing yourself with questions rather than re-reading notes passively. This is where dedicated CPR practice quizzes become invaluable. Research on learning science consistently demonstrates that retrieval practice (answering questions from memory) produces dramatically better long-term retention than passive review. Using the quizzes available on PracticeTestGeeks.com, you can target specific domains — adult CPR, AED use, pediatric and infant CPR, the ACLS algorithm — and identify gaps in your knowledge before your exam day.

Another high-yield study approach is understanding the common errors tested on CPR exams. These include: failing to check scene safety before approaching, incorrect hand placement (too high on the sternum), insufficient compression depth or rate, interrupting compressions for more than 10 seconds, delivering rescue breaths too forcefully or too long, and failing to allow full chest recoil. Exam questions are frequently built around these error patterns, asking candidates to identify what a rescuer did wrong in a described scenario or to select the best next action.

For those studying the ACLS algorithm specifically, the most important domains to master are the two cardiac arrest algorithm pathways (shockable vs. non-shockable rhythms), the timing and dosing of epinephrine (1 mg IV/IO every 3–5 minutes), the indications for amiodarone or lidocaine in refractory VF or pVT, and the post-cardiac arrest care bundle including targeted temperature management and coronary angiography. ACLS written exams typically require a minimum score of 84 percent, and the skills station requires competency demonstration across multiple scenarios.

PALS certification candidates face a similarly rigorous two-component assessment: a written exam with a passing threshold of 84 percent, and skills stations covering pediatric cardiac arrest management, respiratory emergencies, and shock recognition and management. The pediatric focus means deeper knowledge of infant CPR technique, weight-based medication dosing, and the specific energy doses used for pediatric defibrillation (2 J/kg for initial shock, 4 J/kg for subsequent shocks) is tested directly. Study resources that include scenario-based questions modeled after real PALS cases are particularly valuable for this certification.

For any certification level, physical mannequin practice remains irreplaceable. CPR skill stations assess your technique directly — an examiner or evaluator watches your compression rate, depth, hand placement, recoil, and ventilation delivery in real time. Cognitive knowledge of the correct numbers means nothing if your body cannot execute the skill under observation. If your course includes a pre-test skills session, use it to identify and correct technical errors before the official evaluation. Most course providers allow additional mannequin practice time for candidates who need it.

Finally, remember that CPR certification is not a one-time achievement — it is an ongoing commitment to being prepared. The two-year certification cycle ensures that your training reflects the most current AHA guidelines and that your skills remain at a standard that could genuinely help someone in an emergency. Between formal recertifications, annual refresher training, combined with regular use of practice quizzes and scenario review, keeps both your knowledge and your confidence at the level needed when it truly matters most.
