CPR Chest Compressions and Airway: Complete Guide

Cardiac arrest strikes without warning. When it does, chest compressions and airway care give a person the best chance to survive. This complete guide explains how both skills work, what the 2025 American Heart Association (AHA) guidelines say, and how you can practice before an emergency happens.
Why CPR Chest Compressions and Airway Skills Save Lives
About 350,000 people in the U.S. suffer an out-of-hospital cardiac arrest each year. Roughly 90% of them die, according to the AHA. The 2025 AHA Guidelines, published in Circulation, report that 10.5% of adults treated by EMS in 2024 survived to hospital discharge.
Bystander CPR makes a clear difference. However, only 41.7% of adults in cardiac arrest received it. The AHA states that immediate CPR can double or triple a person’s chance of survival. In other words, a trained bystander can change the outcome.
How to Do Chest Compressions on an Adult
Chest compressions pump blood to the brain and heart when the heart stops. Quality matters most. Follow these steps:
- Check the scene, tap the person, and shout for help.
- Call 911 and send someone to get an AED.
- Place the heel of one hand on the lower half of the breastbone. Put your other hand on top.
- Lock your elbows and keep your shoulders over your hands.
- Push hard and fast, and do not stop until help arrives.
The AHA sets four clear targets:
- Rate: 100 to 120 compressions per minute.
- Depth: at least 2 inches (5 cm), but no more than 2.4 inches (6 cm).
- Recoil: let the chest rise fully after each push.
- Pauses: keep every interruption as short as possible.
Fatigue lowers quality quickly. Therefore, switch compressors every 2 minutes, or sooner if you tire. Also, work on a firm surface. Faster rates often lead to shallow pushes, so hold a steady beat. Many rescuers use the tempo of “Stayin’ Alive” to stay on pace.
The 2025 guidelines add one key message. Do not delay compressions. Start right away, and perform CPR where you find the person whenever it is safe.
How to Open the Airway During CPR
Compressions move blood, but that blood needs oxygen. A clear airway lets air reach the lungs. In an unresponsive person, the tongue is the most common blockage.
Use the head tilt-chin lift to open the airway:
- Place one hand on the forehead.
- Lift the chin with two fingers of your other hand.
- Tilt the head back gently.
Healthcare providers may use a jaw thrust if they suspect a spinal injury. If the jaw thrust does not open the airway, they switch to the head tilt-chin lift. Opening the airway takes only a few seconds, so never let it delay your compressions.
How to Give Rescue Breaths Safely
Trained rescuers give breaths with a mouth-to-mouth seal or a bag-mask device. Each breath should last about 1 second and make the chest visibly rise. Do not blow hard or fast. Too much air raises pressure in the chest and reduces blood flow.
The standard adult ratio is 30 compressions followed by 2 breaths. Keep each pause for breaths short. After the breaths, resume compressions at once. Once a provider places an advanced airway, compressions run continuously. Breaths then come about every 6 seconds.
Hands-Only CPR vs. Conventional CPR
If you have no training, do hands-only CPR. Push hard and fast on the center of the chest without stopping for breaths. This method works well for adults who collapse suddenly.
If you have training, add breaths. Children and drowning victims especially need them, because breathing problems often cause their arrests. As a result, a CPR class that teaches both methods prepares you for any situation.
Common CPR Mistakes to Avoid
Even trained rescuers slip under stress. Watch for these errors:
- Pushing too shallow or too deep.
- Leaning on the chest between compressions.
- Pausing too long to check or breathe.
- Giving breaths too hard or too fast.
- Waiting to start because you feel unsure.
Feedback devices and manikins help you fix these habits. Hands-on practice with an instructor builds the muscle memory you need.
