Every year in the United States, more than 7,000 infants experience out-of-hospital cardiac arrests, and around 20,000 have in-hospital cardiac arrests (AHA, 2025). Most out-of-hospital cases, about 80 percent, happen at home, where a single rescuer is often the first and only person who can act. Survival to hospital discharge varies widely, ranging from 6%-38% for out-of-hospital arrests and 38%-66% for in-hospital arrests, while favorable neurologic outcomes are higher in hospital cases, between 64%-89%.
If you are the only rescuer, acting quickly and correctly can make all the difference. The American Heart Association recommends a 30 to 2 compression-to-breath ratio for 1-rescuer infant CPR. This rhythm keeps oxygen circulating while maintaining blood flow to vital organs. Practicing this technique and understanding the correct ratio can significantly improve an infant’s chance of survival and reduce the risk of long-term complications.
This blog explains the correct 1-rescuer infant CPR ratio and how to perform it safely. Following AHA and ILCOR guidelines, it shows how one rescuer can maintain oxygen and blood flow until help arrives.
Why Is the Compression-to-Breath Ratio Critical for Infant Survival?
The compression-to-breath ratio is critical for infant survival because most cardiac arrests in infants result from breathing problems rather than heart issues. According to the American Heart Association (AHA) and ILCOR, chest compressions circulate oxygen-rich blood to vital organs. Rescue breaths provide oxygen that the infant cannot take in on their own. Using a balanced ratio prevents hypoxia, maintains blood flow, and ensures you can give effective CPR, especially when acting alone.
Key points:
- Chest compressions circulate oxygenated blood to vital organs.
- Rescue breaths supply oxygen to the infant who cannot breathe on their own.
- A balanced ratio prevents hypoxia while maintaining circulation.
- Following this ratio ensures effective CPR when you are the sole rescuer.
What Is the Life-Saving Compression-to-Breath Ratio for 1-Rescuer Infant CPR?
The life-saving compression-to-breath ratio for a single rescuer performing infant CPR is 30 chest compressions to 2 rescue breaths, following guidance from the American Heart Association (AHA) and pediatric BLS guidelines. This ratio is designed to maintain blood flow to vital organs while delivering oxygen, giving the infant the best chance of survival. Performing the compressions and breaths correctly and without unnecessary interruptions is critical for effective CPR.
Key Highlights
- Perform 30 continuous compressions at a rate of 100-120 per minute.
- Compress the chest about 1.5 inches (4 cm) or one-third of its depth.
- Give 2 gentle rescue breaths, each about 1 second with visible chest rise.
- Repeat the cycle without unnecessary interruptions to maintain circulation and oxygenation.
How Do You Perform 1-Rescuer Infant CPR Step by Step to Save a Life?
Knowing how to perform 1-rescuer infant CPR is crucial because every second counts when an infant becomes unresponsive. Following the American Heart Association guidelines ensures you provide the right compressions and rescue breaths to maintain blood flow and oxygen, giving the infant the best chance of survival until help arrives.
Here are the 1-rescuer infant CPR steps as follows:
1. Check Responsiveness and Breathing
First, assess the infant carefully. When you check for the responsiveness, tap the infant’s foot and call out to see if there’s any response. Look for normal breathing and check the brachial pulse on the upper arm for 5-10 seconds. This helps you quickly determine if CPR is necessary and ensures you act without delay.
2. Begin Chest Compressions
Place two fingers just below the nipple line and compress the chest about 1.5 inches (4 cm) at a rate of 100-120 per minute. Allow full chest recoil after each compression. Following this method, as recommended by the AHA, ensures blood circulates effectively to vital organs while minimizing fatigue.
3. Give Rescue Breaths
Gently tilt the infant’s head back and lift the chin to open the airway. Cover the infant’s mouth and nose with your mouth and deliver 2 gentle breaths, watching for visible chest rise. You should give each breath for about 1 second, ensuring oxygen reaches the lungs without causing harm.
4. Repeat the Cycle
Continue cycles of 30 compressions followed by 2 breaths. If you are alone, perform CPR for 2 minutes before calling emergency services. Consistently following this rhythm ensures the infant receives both circulation and oxygen, maintaining vital functions until additional help arrives.
5. Monitor and Adjust as Needed
Always watch for signs of life, including movement or breathing, and adjust compressions and breaths accordingly. Stay calm and maintain proper technique throughout. You must remain attentive to the infant’s response, ensuring that your efforts are effective and aligned with recommended guidelines.
How Does 1-Rescuer Infant CPR Compare to 2-Rescuer Infant CPR?
Understanding how 1-rescuer and 2-rescuer infant CPR differ helps you see why the 30:2 ratio is crucial when you are alone. With two rescuers, tasks are shared, your fatigue is lower, and breaths can be delivered more frequently, making CPR more efficient and effective.
Here is the comparison table between 1-Rescuer and 2-Rescuer Infant CPR
Criteria | 1-Rescuer Infant CPR | 2-Rescuer Infant CPR |
Compression-to-Breath Ratio | 30:2 | 15:2 |
Compression Method | Two fingers | Two-thumb encircling |
Compression Rate | 100-120 per minute | 100-120 per minute |
Compression Depth | 1.5 Inches | 1.5 Inches |
Role Division | Same rescuer | Shared roles |
Fatigue Management | Higher | Lower |
Do You Know the Most Common Infant CPR Errors to Avoid?
Even experienced rescuers can make mistakes during infant CPR, which can reduce its effectiveness. Knowing the most common errors helps you perform CPR more safely and efficiently. Following the recommended 30:2 compression-to-breath ratio ensures oxygen continues circulating and minimizes potential complications while you provide life-saving care.
Common Mistakes to Avoid During Infant CPR:
1. Compressing Too Shallow or Too Deep
If you compress too shallowly, blood flow to the infant’s vital organs is inadequate. Too deep can cause injury. You should compress about one-third of the chest depth, roughly 1.5 inches, ensuring effective circulation while keeping the infant safe.
2. Giving Breaths That Are Too Forceful or Too Rapid
Overly strong or rapid breaths can cause air to enter the stomach, leading to vomiting or airway obstruction. You should deliver 2 gentle breaths, each lasting about 1 second, while watching for a visible chest rise to confirm effectiveness.
3. Interrupting Compressions Excessively
Pausing chest compressions for too long reduces blood flow to the brain and heart. You should minimize interruptions and maintain the 30 compressions to 2 breaths rhythm, keeping circulation steady while you deliver rescue breaths efficiently.
4. Failing to Allow Full Chest Recoil
Not letting the chest fully expand after each compression prevents proper blood return to the heart. You should allow complete chest recoil between compressions, which helps maintain effective circulation and increases the infant’s chances of survival.
5. Ignoring the Recommended Ratio
Not following the 30:2 ratio can compromise oxygen delivery and circulation. You should always maintain this rhythm when performing 1-rescuer infant CPR, balancing compressions and rescue breaths while you continue until emergency help arrives.
