Heartsaver Adult CPR Algorithm

Bradycardia acls algorithm

When someone suddenly collapses, knowing what to do can make the difference between life and death. The American Heart Association (AHA) developed the Heartsaver Adult CPR Algorithm to give everyday people a clear, step-by-step guide for responding to cardiac emergencies. This framework is designed to be simple and effective, empowering you to act confidently when every second matters.

What is the Heartsaver Adult CPR Algorithm?

The Heartsaver Adult CPR Algorithm is a sequence of actions recommended by the American Heart Association for providing basic life support to an adult who is unresponsive and not breathing normally. It is a critical component of the “Chain of Survival,” a series of coordinated efforts that maximize the chances of survival after a sudden cardiac arrest.

The algorithm emphasizes a few core actions:

  • Immediately recognizing the emergency and calling for help.
  • Performing high-quality chest compressions to keep blood circulating.
  • Providing rescue breaths.
  • Using an AED as soon as it becomes available.

Following these steps ensures that the victim receives the best possible care until professional medical help arrives.

A Step-by-Step Breakdown of the Algorithm

In a high-stress situation, it’s easy to feel overwhelmed. The Heartsaver Adult CPR Algorithm breaks down the process into manageable steps. Let’s review them one by one.

1. Check for Safety and Responsiveness

Before you do anything else, make sure the scene is safe for both you and the victim. Look for any immediate dangers like traffic, fire, or electrical hazards.

Once you confirm the area is safe, check if the person is responsive.

  • Tap their shoulder firmly and shout, “Are you okay?”
  • Simultaneously, scan their chest for signs of normal breathing for no more than 10 seconds.

It’s important to distinguish between normal breathing and agonal gasps. Agonal gasps are short, sharp, or snorting breaths that are not effective for getting air into the lungs. These are a sign of cardiac arrest, not recovery. If the person is only gasping, you should proceed as if they are not breathing.

2. Get Help Immediately

If the person is unresponsive and not breathing or only gasping, it’s time to get help.

  • If someone else is nearby: Point to a specific person and tell them, “You! Call 911 and get an AED!” Being direct prevents confusion and ensures someone takes action.
  • If you are alone: Call 911 yourself. Place your phone on speaker mode so you can communicate with the dispatcher while you begin CPR. The dispatcher can provide instructions and support until help arrives.

Activating the emergency response system as quickly as possible is vital. It starts the process of getting advanced medical care to the scene.

3. Begin High-Quality Chest Compressions

Immediate chest compressions are the cornerstone of effective CPR. They manually pump the heart, circulating oxygenated blood to the brain and other vital organs.

Here’s how to perform them correctly:

  • Position the person on their back on a firm, flat surface.
  • Kneel beside their chest.
  • Place the heel of one hand on the center of their chest, right between the nipples.
  • Place your other hand on top of the first and interlace your fingers.
  • Keep your arms straight and your shoulders directly over your hands.
  • Push hard and fast, compressing the chest at a rate of 100 to 120 compressions per minute. (Singing the song “Stayin’ Alive” can help you maintain the right rhythm).
  • The compression depth should be at least 2 inches (5 cm) but no more than 2.4 inches (6 cm) for an adult.
  • Allow the chest to recoil completely after each push. This allows the heart to refill with blood before the next compression.

4. Provide Rescue Breaths

After 30 chest compressions, you should give two rescue breaths. This provides a small amount of oxygen to the lungs.

  • Open the airway using the head-tilt, chin-lift technique. Place one hand on the person’s forehead and gently tilt their head back. With your other hand, lift the chin to open the airway.
  • Pinch the person’s nose shut.
  • Take a normal breath (not a deep one) and make a complete seal over their mouth with yours.
  • Give one breath lasting about 1 second, watching to see if the chest rises.
  • If the chest rises, give a second breath. If it doesn’t, reposition the head and try the head-tilt, chin-lift again before giving the second breath.
  • Immediately return to chest compressions after delivering the breaths.

Do not interrupt compressions for more than 10 seconds to give breaths. The focus should always be on minimizing interruptions to chest compressions.

5. Continue CPR Cycles

Continue the cycle of 30 compressions followed by 2 breaths. If another person trained in CPR is available, you should switch roles every 2 minutes (or after about five cycles). This prevents fatigue and ensures the compressions remain high-quality.

6. Use an AED When Available

An Automated External Defibrillator (AED) is a portable device that can analyze the heart’s rhythm and deliver an electrical shock (defibrillation) to restore a normal heartbeat. Using an AED is a crucial step in the Chain of Survival.

  • As soon as the AED arrives, turn it on.
  • Follow the device’s voice and visual prompts.
  • Attach the electrode pads to the person’s bare chest as shown in the diagrams on the pads.
  • The AED will analyze the heart’s rhythm. Ensure no one is touching the person during this time.
  • If a shock is advised, the device will charge. Make sure everyone is clear by shouting, “Clear!” before pressing the shock button.
  • Immediately after the shock is delivered, resume chest compressions. Do not wait for the AED to reanalyze. Continue CPR until the device prompts you to stop.

If no shock is advised, immediately resume chest compressions.

7. Know When to Stop CPR

You should continue performing CPR until one of the following occurs:

  • The person shows obvious signs of life, such as breathing normally or moving.
  • An AED is ready to analyze the person’s heart rhythm.
  • Another trained rescuer takes over for you.
  • Emergency medical services (EMS) personnel arrive and take over.
  • You become too exhausted to continue safely.
