Which action improves the quality of chest compressions delivered during a resuscitation attempt?

1. Increase the compression rate

2. Switch providers every minute

3. Switch providers about every 2 minutes or every 5 compression cycles

4. Maintain the same provider throughout

The correct answer is: Switch providers about every 2 minutes or every 5 compression cycles

Switching providers about every 2 minutes or after every 5 compression cycles is recognized as an effective strategy to maintain the quality of chest compressions during a resuscitation attempt. This practice helps prevent provider fatigue, which can lead to a decrease in the effectiveness of chest compressions over time. Fatigue sets in quickly when performing compressions, as it is physically demanding to maintain the required rate and depth. By rotating providers regularly, the team ensures that each provider is performing at their optimal capacity, delivering compressions that are consistent in both rate and depth. Additionally, the timing of these switches is also critical. The recommendation to switch every 2 minutes aligns with the overall rhythm of CPR, allowing for a structured and efficient transition that minimizes interruptions to chest compressions. This approach not only enhances the quality of compressions but also improves the overall chances of a successful resuscitation outcome.
