Infants are among the most vulnerable individuals in any emergency situation. When a baby stops breathing or their heart stops, every second counts, and knowing exactly what to do can make all the difference before emergency services arrive.
Infant CPR training equips parents, caregivers, childcare providers, and healthcare professionals with the hands-on skills needed to respond confidently in those critical moments. Yet infant CPR is not simply a scaled-down version of adult CPR. The technique is meaningfully different, and understanding those differences is the first step toward being genuinely prepared.
This guide walks you through the complete process of learning and performing infant CPR, from recognizing an emergency to delivering rescue breaths and chest compressions correctly. You will also learn how to respond to a choking infant and why formal, hands-on certification is the most effective way to build real confidence in these skills.
Whether you are a new parent, a daycare worker, a pediatric nurse, or simply someone who wants to be ready, this step-by-step guide covers everything you need to know. By the end, you will understand correct hand placement, compression depth, rescue breath technique, and the critical differences between a cardiac arrest and a choking emergency.
Important note: This guide is for educational purposes only. It does not replace formal, hands-on infant CPR training from a certified instructor. Always seek professional certification through an accredited program before attempting CPR in a real emergency.
Step 1: Understand Why Infant CPR Is Different from Adult CPR
Before you can perform infant CPR correctly, you need to understand why the technique exists in the first place. Applying adult CPR methods to an infant is not just ineffective; it can cause serious injury. The anatomical and physiological differences between infants and adults are significant enough to require an entirely separate set of guidelines.
First, let's define the age range. Infant CPR technique applies to children from birth through 12 months of age. Once a child reaches their first birthday, the child CPR technique takes over, which continues through puberty. This distinction matters, and knowing it helps you respond appropriately based on who is in front of you.
Here is what makes infant anatomy unique:
Proportionally larger head: An infant's head is large relative to their body. This affects how you position the airway, as tilting the head too far back can actually close off the airway rather than open it.
Softer, more compressible airway: Infants have softer tracheal tissue than adults. Excessive pressure or over-tilting can compress the trachea and block airflow entirely.
More flexible ribcage: While this might sound like it makes compressions easier, it also means that improper technique can cause rib fractures or internal injury more readily if force is poorly directed.
Smaller lung capacity: Infants need only small puffs of air during rescue breathing, not full adult-sized breaths. Over-inflating the lungs can force air into the stomach, causing gastric inflation and increasing the risk of vomiting.
The compression-to-ventilation ratios also differ from adult CPR. For a single rescuer performing infant CPR, the ratio is 30 compressions to 2 rescue breaths, the same as adult CPR. However, when two trained healthcare providers are working together on an infant, the ratio changes to 15 compressions to 2 breaths. This two-rescuer protocol allows for more frequent ventilations, which is particularly important for infants whose oxygen demands are higher relative to their body size.
Understanding these differences is not just academic. It shapes every decision you make during an infant emergency, from how you position the head to how hard you press during compressions. If you want to compare these protocols side by side, reviewing CPR steps for adults and understanding the difference between CPR and BLS can provide helpful context for how these guidelines evolve across age groups.
Step 2: Assess the Scene and Check the Infant for Responsiveness
In any emergency, your first instinct might be to rush immediately to the infant. Resist that urge for just a moment. A rapid scene assessment protects both you and the baby, because an unsafe environment can turn one victim into two.
Scan the area quickly. Is there a hazard like a gas leak, unstable furniture, or electrical danger? If the scene is unsafe, do not enter until it is secured. If the scene is safe, approach the infant immediately.
Now check for responsiveness. With infants, you never shake them to check for a response. Shaking can cause serious neurological injury. Instead, tap the bottom of the infant's foot firmly with your finger. Call out to the baby in a loud, clear voice. Watch for any reaction: movement, a cry, a change in facial expression, or any sign of awareness.
An unresponsive infant will show no reaction to stimulation, no purposeful movement, and will appear limp. Pay close attention to their breathing. Normal breathing has a regular rhythm and visible chest rise. What you want to avoid mistaking for normal breathing is agonal breathing, also called gasping. Agonal breathing consists of irregular, infrequent gasps that can look like breathing but are actually a sign of cardiac arrest. If the infant is gasping or not breathing at all, treat this as a cardiac arrest and begin CPR.
At this point, you need to call 911 or have someone else call immediately. If there is another person present, point directly at them and say, "You, call 911 now." Giving a specific instruction to a specific person is far more effective than a general call for help in a crowd.
If you are alone with the infant, the protocol changes slightly. Because infants are small enough to carry, you can bring the baby with you to a phone if needed. However, the general guidance for lone rescuers is to perform two minutes of CPR first before leaving to call 911. Two minutes of CPR provides critical circulation before you step away, and many modern smartphones can be used hands-free so you can call while continuing compressions.
One of the most common mistakes in this stage is spending too much time trying to rouse the infant, repositioning them, or waiting to see if they recover on their own. If the baby is unresponsive and not breathing normally, act immediately. Time is the most critical variable in a cardiac arrest.
Step 3: Position the Infant and Open the Airway
Proper positioning is the foundation of effective infant CPR. If the airway is not open, rescue breaths will not deliver oxygen, and the entire effort loses its purpose.
Place the infant on a firm, flat surface. The floor is ideal. A soft mattress or couch allows the body to sink, which reduces the effectiveness of chest compressions. If you are in a clinical setting, a firm examination table works well. The surface needs to be stable and unyielding.
Once the infant is on their back, you will perform the head-tilt chin-lift maneuver, but with an important modification specific to infants. In adults, you tilt the head back significantly to open the airway. In infants, you use what is called the neutral or "sniffing position." This means tilting the head only slightly, just enough so the nose points straight up toward the ceiling, as if the infant were sniffing the air.
To achieve this position, place one hand gently on the infant's forehead and use one or two fingers of your other hand to lift the bony part of the chin upward. Avoid pressing on the soft tissue under the chin, as this can push the tongue back and actually obstruct the airway.
Here is why over-tilting is a serious risk: because an infant's head is proportionally large and their neck is short, tilting the head too far back causes the soft trachea to kink, much like bending a garden hose. This closes off the very airway you are trying to open. The sniffing position keeps the trachea aligned without compressing it.
Once the airway is open, take a brief look inside the mouth. If you can clearly see a visible obstruction, you may carefully remove it. Do not perform blind finger sweeps. Probing the mouth without seeing an object can push it deeper into the airway, making the situation significantly worse.
If you have any reason to suspect a spinal injury, such as a fall from height or a traumatic impact, use the jaw-thrust maneuver instead. This involves placing your fingers behind the angles of the jaw and lifting forward without tilting the head. This technique opens the airway while keeping the spine as still as possible.
Step 4: Deliver Rescue Breaths Correctly
With the airway open, you are ready to deliver rescue breaths. The technique for infants differs from the adult mouth-to-mouth method in one important way: you cover both the infant's mouth and nose with your mouth simultaneously.
This is called the mouth-to-mouth-and-nose technique. Because an infant's face is small, your mouth can seal over both openings at once, which creates a more effective seal and ensures air goes where it needs to go.
Here is how to do it correctly:
1. Maintain the neutral head position you established in Step 3. Do not let the head fall out of alignment while you move to deliver breaths.
2. Take a normal breath, not a deep one. You do not need to fill your lungs completely before delivering a breath to an infant.
3. Seal your mouth over the infant's mouth and nose, creating a firm but gentle seal.
4. Deliver a small puff of air, just enough to see the chest visibly rise. Think of it as the amount of air you would use to blow out a single birthday candle. Watch the chest as you breathe in; if it rises, the breath was delivered successfully.
5. Remove your mouth and allow the chest to fall naturally before delivering the second breath.
Deliver 2 initial rescue breaths before beginning chest compressions. If the chest does not rise on the first attempt, recheck the head position and try again. A chest that does not rise usually means the airway is not properly aligned, the seal is not tight enough, or there may be an obstruction.
The most common mistake at this stage is blowing too hard. Excessive breath volume causes gastric inflation, where air is forced into the stomach instead of the lungs. This makes the stomach distend, which pushes up against the diaphragm and reduces lung capacity. It can also cause the infant to vomit, creating an airway obstruction at the worst possible moment.
In a formal training setting, you will also learn to use barrier devices such as pocket masks or face shields. These are recommended whenever available to reduce the risk of disease transmission. A quality infant CPR course will include practice with these devices so their use becomes second nature. If you are interested in comprehensive pediatric emergency training that includes rescue breathing, exploring a pediatric first aid certification course is an excellent next step alongside infant CPR training.
Step 5: Perform Chest Compressions with the Two-Finger Technique
Chest compressions are the mechanical heart of CPR. They manually pump blood through the body when the heart cannot do it on its own, keeping oxygen-rich blood flowing to the brain and vital organs until normal heart rhythm can be restored.
For infants, two compression techniques are used depending on how many rescuers are present.
The two-finger technique (single rescuer): Place two fingers, typically your index and middle fingers, on the center of the infant's chest, just below the nipple line. The exact landmark is the lower half of the breastbone (sternum). Your fingers should point downward toward the infant's feet, not sideways.
The two-thumb encircling technique (two healthcare providers): When a second trained rescuer is present, the preferred method is to wrap both hands around the infant's torso with thumbs placed side by side on the center of the chest, just below the nipple line. The fingers wrap around the back to support the spine. This technique generates more consistent compression depth and allows the second rescuer to manage the airway and deliver breaths more effectively. Research in healthcare education consistently supports this two-thumb technique as producing superior compression quality in two-rescuer scenarios.
Regardless of which technique you use, the compression parameters are the same:
Depth: Compress approximately 1.5 inches, which is roughly one-third of the infant's chest depth from front to back. This may feel deeper than you expect, especially if you are worried about causing injury. Compressions that are too shallow do not generate enough pressure to circulate blood effectively. Trust the guidelines and compress with intention.
Rate: Deliver compressions at a rate of 100 to 120 compressions per minute. This is a brisk, rhythmic pace. Many instructors suggest counting aloud or using a mental rhythm to maintain the correct rate during practice.
Full chest recoil: After each compression, allow the chest to fully return to its natural position before beginning the next compression. This recoil phase allows the heart to refill with blood between compressions. Do not lean on the chest or keep pressure applied between compressions, but do keep your fingers in contact with the chest to maintain your landmark position.
The compression-to-breath ratio follows the same pattern introduced earlier: 30 compressions followed by 2 rescue breaths for a single rescuer, and 15 compressions followed by 2 rescue breaths when two trained healthcare providers are working together.
The most common pitfall at this stage is compressions that are too shallow. Many people hold back out of fear of injuring the infant, and that hesitation is understandable. However, ineffective compressions are themselves harmful because they fail to circulate blood to the brain. Hands-on training with a manikin is the most effective way to overcome this hesitation and develop the muscle memory needed to compress with appropriate depth and confidence.
For a broader review of compression technique principles, exploring resources on how to perform CPR correctly can reinforce the fundamentals across all age groups.
Step 6: Respond to an Infant Choking Emergency
Choking and cardiac arrest are two distinct emergencies that require different responses. Confusing the two or applying the wrong technique can make the situation significantly worse. Knowing which situation you are dealing with is critical.
In a cardiac arrest, the infant is unresponsive and not breathing. You begin CPR immediately as described in the steps above.
In a choking emergency, the infant is conscious but cannot breathe effectively because something is blocking their airway. The signs of severe choking in an infant include a silent or very weak cry, an inability to cough forcefully, a bluish or grayish color around the lips and fingernails (called cyanosis), and visible distress or panic. If the infant is coughing forcefully, that is a sign the airway is only partially blocked and the body is doing its job. Encourage the cough and monitor closely without intervening.
When the obstruction is severe and the infant cannot clear it on their own, use the back blow and chest thrust sequence:
1. Hold the infant face-down along your forearm, supporting the head with your hand. The infant's head should be lower than their chest. Use your thigh for additional support if needed.
2. Deliver 5 firm back blows between the shoulder blades using the heel of your free hand. These blows should be deliberate and forceful, not gentle pats.
3. Turn the infant face-up along your other forearm, keeping the head supported and lower than the body.
4. Deliver 5 chest thrusts using two fingers placed on the center of the chest, the same landmark used for CPR compressions. Each thrust should be a firm downward push.
5. After each set of 5 back blows and 5 chest thrusts, look in the mouth. If you can clearly see the object, remove it carefully. Never perform a blind finger sweep.
6. Repeat this cycle until the object is dislodged or the infant becomes unresponsive.
If the infant loses consciousness at any point during a choking emergency, place them on a firm, flat surface and begin CPR. Each time you open the airway to deliver rescue breaths, look in the mouth for the object before attempting to ventilate.
One critical warning: do not perform abdominal thrusts (the Heimlich maneuver) on an infant. This technique is not recommended for infants because their abdominal organs are highly vulnerable to compression injury. The back blow and chest thrust sequence is the correct protocol per American Heart Association guidelines for this age group.
Step 7: Get Certified Through Hands-On Infant CPR Training
Reading this guide is a valuable starting point. But it is not a substitute for hands-on infant CPR training, and it is important to be direct about that distinction.
CPR is a psychomotor skill, which means it lives in your muscles and your reflexes, not just your memory. Healthcare education research consistently recognizes that hands-on practice with a manikin is far superior to video or reading-based learning alone when it comes to building the kind of automatic, confident response that an emergency demands. When a real baby is in front of you and adrenaline is flooding your system, you need your hands to know what to do without your brain having to calculate every step.
A quality infant CPR certification course includes several essential components:
Manikin practice: You will practice compressions and rescue breaths on an infant-sized manikin, which gives you direct feedback on compression depth, hand placement, and breath volume. This tactile experience is irreplaceable.
Scenario-based learning: Good courses walk you through realistic emergency scenarios so you practice decision-making under simulated pressure, not just isolated techniques.
Skills assessment: A certified instructor observes your technique and provides corrections in real time, ensuring you leave the course with accurate, effective skills rather than reinforced bad habits.
It is also worth understanding the difference between a basic CPR certification and a BLS (Basic Life Support) certification. Basic CPR certification is appropriate for parents, grandparents, childcare workers, and community members who want to be prepared. BLS certification is designed for healthcare providers, including pediatric nurses, pediatricians, emergency medical technicians, and other clinical staff who may need to perform infant CPR in a professional setting. BLS courses cover two-rescuer techniques, advanced airway management, and team-based response protocols in greater depth.
Certification is not a one-time event. Skills fade over time without practice, and guidelines are updated periodically as new evidence emerges. Most certifications require renewal every two years, and staying current ensures your skills reflect the latest evidence-based protocols.
Who should prioritize infant CPR training? Parents and expectant parents top the list, but grandparents, childcare workers, babysitters, pediatric healthcare providers, school staff, and anyone who regularly spends time around infants should have current certification.
Midwest CPR Center offers accredited infant CPR training programs throughout the Midwest, with courses designed for both community members and healthcare professionals. Whether you are looking for CPR classes for parents, exploring the best CPR certification courses for your team, weighing BLS certification online vs. in person, or simply searching for CPR certification near you, finding a certified course is the most important action you can take after reading this guide.
Your Infant CPR Readiness Checklist
Before you close this guide, take a moment to review the seven steps you have covered. Use this as a quick reference checklist to confirm your understanding:
1. Understand the differences: Infant CPR uses distinct techniques from adult CPR, including the sniffing head position, mouth-to-mouth-and-nose rescue breaths, two-finger compressions, and different compression-to-breath ratios.
2. Assess and check responsiveness: Ensure the scene is safe, tap the foot to check for response, recognize agonal breathing, and call 911 or direct a bystander to call immediately.
3. Position and open the airway: Place the infant on a firm surface, use the neutral sniffing position, avoid over-tilting, and check for visible obstructions without blind finger sweeps.
4. Deliver rescue breaths correctly: Cover both mouth and nose, use small puffs of air, watch for chest rise, and avoid over-inflating.
5. Perform chest compressions: Use the two-finger technique at 100 to 120 compressions per minute, compress to 1.5 inches depth, allow full chest recoil, and follow the 30:2 or 15:2 ratio.
6. Respond to choking: Use back blows and chest thrusts, never abdominal thrusts, and transition to CPR if the infant becomes unresponsive.
7. Get certified: Complete hands-on training with a certified instructor and renew your certification regularly.
One final and important reminder: skills fade. Even after completing a certification course, practicing regularly and staying current with your recertification requirements keeps your response sharp and your knowledge accurate. Understanding CPR recertification requirements in your area helps you plan ahead and stay prepared year after year.
