After 30 Chest Compressions: What's the Next Step in CPR?

Cardiopulmonary resuscitation (CPR) is a life-saving technique used when someone stops breathing or their heart stops beating. The process is a crucial chain of events, and knowing the precise steps is vital. This article focuses on what to do after performing 30 chest compressions, a key part of the sequence.

The 30:2 Ratio in CPR

Modern CPR guidelines emphasize a consistent 30:2 ratio. This means performing 30 chest compressions followed by two rescue breaths. This ratio is designed to maximize the chances of circulating oxygenated blood to the brain and vital organs.

After 30 Compressions: Administering Rescue Breaths

After completing 30 chest compressions, the next step is to give two rescue breaths. Here's how:

1. Open the Airway: Gently tilt the person's head back and lift their chin. This helps to open their airway.

2. Pinch the Nose (Optional): For some people, pinching the nose shut helps create a better seal.

3. Seal the Mouth: Create a seal around the person's mouth with yours, covering their mouth completely.

4. Give Rescue Breaths: Give two slow breaths, each lasting about one second. Look for the chest to rise as you breathe into the person. If the chest doesn't rise, re-adjust the head tilt and try again. If it still doesn't rise, there may be an airway obstruction.

Important Considerations After Rescue Breaths:

• Continue the Cycle: After the two rescue breaths, immediately resume chest compressions with another set of 30. Repeat this 30:2 cycle until:

  • Help arrives.
  • The person shows signs of life (breathing normally, coughing, moving).
  • You are too exhausted to continue.

• Airway Obstruction: If you have difficulty giving rescue breaths, suspect an airway obstruction. Attempt to clear the obstruction by giving back blows and abdominal thrusts (Heimlich maneuver) if appropriate.

• One-Rescuer vs. Two-Rescuer CPR: The 30:2 ratio applies to both one-rescuer and two-rescuer CPR. In a two-rescuer scenario, one person performs compressions while the other gives breaths, switching roles as needed.

• Using an AED: If an automated external defibrillator (AED) is available, use it as soon as possible. Follow the AED's instructions. The AED may interrupt the CPR cycle, but it is essential for improving survival chances.

In Conclusion:

The steps following 30 chest compressions are crucial in maintaining the effectiveness of CPR. Remember the 30:2 ratio – 30 chest compressions followed by two rescue breaths – and continue this cycle until help arrives or the person shows signs of recovery. If you are unsure about any aspect of CPR, it's vital to complete a certified CPR course. This training provides hands-on practice and reinforces the critical steps involved in saving a life.
