When performing CPR, how often should team members rotate their roles?

In the context of CPR, rotating team members every 2 minutes is crucial to maintain effective compressions and prevent fatigue. This allows rescuers to perform at their optimal levels, ensuring that high-quality chest compressions continue without significant interruptions. When rescuers become fatigued, the quality of compressions may decline, reducing blood flow to the heart and brain during cardiac arrest.

The 2-minute interval aligns with the recommendations from organizations like the American Heart Association. It provides an opportunity for rescuers to switch roles effectively, allowing one person to take over chest compressions while others may assist with airway management or use an automated external defibrillator (AED) if needed.

Other time frames, such as every minute or every 5 minutes, do not support the need for maintaining high-quality compressions. Rotating after each ventilation is impractical, as chest compressions should not be interrupted too frequently; continuous high-quality compressions are emphasized during CPR to optimize patient outcomes.
