Two-Rescuer CPR: The 30:2 Ratio for Adult Patients

When facing a life-threatening situation like cardiac arrest, every second counts. Performing Cardiopulmonary Resuscitation (CPR) can buy precious time for the heart to regain its rhythm and for emergency medical services to arrive. While a single rescuer can perform CPR effectively, having two rescuers significantly increases the chances of survival.

The Golden Ratio: 30:2

In two-rescuer adult CPR, the American Heart Association (AHA) recommends a compression-to-ventilation ratio of 30:2. This means that for every 30 chest compressions delivered, two rescue breaths are given.

Why 30:2?

This ratio is based on the following scientific reasoning:

• Maximizing Blood Circulation: Compressions are the primary way to circulate blood throughout the body, delivering oxygen to vital organs. More compressions mean more blood flow and better chances of survival.

Sanders)
• Efficient Oxygen Delivery: While rescue breaths help ensure oxygen reaches the lungs, the primary goal is to keep the heart pumping. Therefore, fewer ventilations are needed in two-rescuer CPR.

Sanders)
• Minimizing Interruptions: The 30:2 ratio allows for a smooth and consistent rhythm of compressions and breaths, minimizing interruptions to chest compressions.

Sanders)

In Practice

Here's how the 30:2 ratio plays out in two-rescuer CPR:

1. Position: One rescuer (the compressions provider) stands on the victim's left side, while the other rescuer (the ventilation provider) kneels on the victim's right side.
2. Rhythm: The compressions provider delivers 30 compressions at a rate of 100-120 per minute, while the ventilation provider delivers two breaths, ensuring each breath lasts about one second.
3. Continuous CPR: This cycle of 30 compressions and 2 breaths repeats continuously until:
   • The victim regains consciousness and shows signs of life.
   • Emergency medical services arrive and take over.
   • The rescuers are physically exhausted and need to be replaced.

The Importance of Training

It's crucial to receive proper training in CPR to ensure proper technique and the right ratio is used. CPR courses are widely available and teach the necessary skills for both one- and two-rescuer situations.

Key Points to Remember:

• Use the 30:2 compression-to-ventilation ratio in two-rescuer adult CPR.
• Maintain a consistent rhythm of compressions and breaths.
• If you're not trained in CPR, call emergency services immediately.

By knowing and applying the correct CPR techniques, you can make a crucial difference in someone's life. Remember, every second counts.
