How often should you switch rescuers during CPR?

Switching rescuers during CPR is critical to maintain high-quality compressions. The recommended practice is to switch rescuers every 2 minutes or after 5 cycles of CPR, which helps to ensure that the person performing chest compressions does not become fatigued.

When rescuers are fresh, they can deliver compressions at the necessary depth and rate, which is vital for maintaining adequate blood flow to vital organs. After about 2 minutes of continuous compressions, fatigue may set in, leading to a decrease in effectiveness.

Maintaining a consistent rhythm and adequate compression quality is essential for increasing the chance of survival for the person experiencing cardiac arrest. The other options may allow for compressions to continue for too long without a change in rescuers, potentially compromising the quality of CPR being delivered.
