What Are the 7 Steps of CPR AHA? A Complete Guide
Posted by Sydney Pulse, APRN at 6:17 am 0 Comment Print
Every minute matters when someone’s heart stops. According to the American Heart Association, immediate CPR can double or even triple a cardiac arrest victim’s chance of survival. Yet far too many bystanders freeze — not because they don’t care, but because they don’t know what to do.
The American Heart Association (AHA) outlines a clear, step-by-step process for performing CPR. These steps give anyone — trained or not — a framework to act fast and act right. Whether you want to refresh your skills or understand the basics before taking a class, this guide walks you through all 7 steps of CPR according to AHA guidelines.
Why CPR Skills Matter Right Now
In 2024, 137,119 out-of-hospital cardiac arrest (OHCA) events were reported to the CARES registry. Bystander CPR was initiated in only 41.7% of those cases. That gap is alarming. Research analyzing nearly 200,000 witnessed cardiac arrests found that people who received bystander CPR within two minutes had an 81% greater chance of surviving to hospital discharge compared to those who received no help.
Time is the enemy. Every minute without CPR and defibrillation reduces survival chances by 7% to 10%. Knowing these 7 steps could make the difference between life and death for someone you love.
The 7 Steps of CPR According to the AHA
Step 1: Assess the Scene for Safety
Before you touch anyone, look around. Check for traffic, downed power lines, fire, or other hazards. You cannot help if you become a victim yourself. Only approach when the scene is safe.
Step 2: Check for Responsiveness
Tap the person firmly on the shoulder and shout, “Are you okay?” Look for any response — movement, sounds, or eye-opening. If the person doesn’t respond, move immediately to the next step. Do not waste time looking for subtle signs.
Step 3: Call 911 and Get an AED
Shout for help. If others are nearby, point to a specific person and say, “You — call 911.” Assign someone else to find an AED (automated external defibrillator). If you are alone, call 911 yourself before starting CPR. Put the phone on speaker so the dispatcher can guide you.
Cardiac arrests in public settings have more than double the survival rate of those at home (21.1% vs. 8.9%), partly because AEDs and trained bystanders are more likely to be available. Getting that AED fast matters enormously.
Step 4: Open the Airway
Place the person on their back on a firm, flat surface. Tilt their head back gently by placing one hand on the forehead and lifting the chin with two fingers from your other hand. This head-tilt, chin-lift technique opens the airway by moving the tongue away from the throat. Do not over-extend the neck.
Step 5: Check for Breathing
Look, listen, and feel for normal breathing for no more than 10 seconds. Watch for chest rise and fall. Listen for breath sounds. Feel for air on your cheek. Gasping does not count as normal breathing — it is a sign of cardiac arrest. If breathing is absent or abnormal, begin CPR.
Step 6: Begin Chest Compressions
This is the most critical step. Position yourself with:
- Hand placement: Heel of one hand on the center of the chest (lower half of the sternum). Place your other hand on top and interlace your fingers.
- Body position: Arms straight, shoulders directly over your hands.
- Compression depth: At least 2 inches for adults.
- Compression rate: 100 to 120 compressions per minute — roughly the beat of “Stayin’ Alive” by the Bee Gees.
The 2025 AHA Guidelines recommend minimizing interruptions and keeping pauses in compressions under 10 seconds. Allow the chest to fully recoil between each compression. Do not lean on the chest.
Step 7: Give Rescue Breaths (If Trained)
After 30 compressions, give 2 rescue breaths. Keep the airway open with the head-tilt chin-lift. Pinch the nose shut. Create a seal over the mouth and breathe in for about one second — just enough to see the chest rise. Then deliver the second breath. Resume compressions immediately. Maintain a 30:2 ratio of compressions to breaths.
If you are untrained or uncomfortable with rescue breaths, hands-only CPR is effective. The AHA states that Hands-Only CPR — continuous chest compressions without rescue breaths — is recommended when an adult or teen collapses unexpectedly in a non-medical setting. Keep pushing until EMS arrives or the person shows clear signs of life.
What Happens After You Start CPR?
Continue CPR until one of three things happens: emergency responders take over, the person begins breathing normally, or an AED is ready to use. When the AED arrives, turn it on and follow its audio prompts immediately. Apply the pads to bare skin, let the device analyze the heart rhythm, and deliver a shock if it advises one. Resume CPR right after the shock.
The 2025 AHA Guidelines emphasize the importance of high-quality chest compressions, early defibrillation, and the integration of advanced resuscitation techniques to improve survival rates and neurological outcomes following cardiac arrest.
CPR for Children and Infants
The 7-step framework applies to pediatric CPR as well, with important differences. For children, compress at least 2 inches deep or one-third of the chest diameter. For infants, compress about 1.5 inches deep at a rate of 100 to 120 compressions per minute. Use the two-thumb encircling hands technique for infants rather than the two-finger technique, which the 2025 AHA Guidelines no longer recommend.
Rescue breaths also carry more weight in pediatric cases, since cardiac arrest in children often results from respiratory failure rather than a primary heart problem.
Common CPR Mistakes to Avoid
Even well-meaning rescuers make errors. Watch out for these:
- Compressions that are too shallow. Depth matters — push hard.
- Interrupting too often. Every pause reduces blood flow to the brain.
- Not letting the chest fully recoil. Incomplete recoil limits how much blood the heart can pump.
- Tilting the head too far. Over-extension can partially close the airway.
- Giving rescue breaths too forcefully. A gentle breath that raises the chest is enough.
