Which of the following statements about performing CPR with two or more rescuers is true?

A. To reduce fatigue, rescuers should switch positions as soon as another rescuer arrives on scene.

B. To reduce rescuer fatigue, rescuers should switch positions about every two minutes or when the AED is analyzing.

C. While one rescuer is performing the primary assessment, the assisting responder should perform ventilations using a BVM.

D. While one rescuer is performing the primary assessment, the assisting responder should place their resuscitation mask on the victim.

Answer

The correct statement about performing CPR with multiple rescuers is option B, which suggests that rescuers should switch positions about every two minutes or whenever the AED is analysing. This helps reduce fatigue and ensures continuous high-quality chest compressions. Effective management of rescuer fatigue is key to increasing the victim's chances of survival during cardiac emergencies.

Explanation

When performing CPR with two or more rescuers, it is important to manage the physical demands on the rescuers effectively. Switching positions during CPR can help reduce fatigue and maintain the quality of chest compressions, which is crucial for the victim's chances of survival.

Among the options provided:

A. This statement suggests switching as soon as another rescuer arrives, which may not be effective for maintaining high-quality CPR.

B. This statement is accurate; to reduce rescuer fatigue, rescuers should switch positions approximately every two minutes or whenever an AED is analyzing the heart rhythm. This timing helps ensure that compressions remain consistent and effective.

C. This is not appropriate; the primary assessment is typically not done simultaneously with CPR.

D. While this may seem logical, it also isn’t effective since it detracts from continuous high-quality compressions necessary during CPR.

In conclusion, the statement that best reflects proper CPR technique with multiple rescuers is option B.
