Answer :
Final answer:
Rescuers should switch positions during CPR about every 2 minutes to maintain high-quality chest compressions and prevent fatigue. Regular switching helps ensure that compressions remain effective and at the required rate. Maintaining this rhythm is crucial for increasing the chances of survival in a cardiac emergency.
Explanation:
When to Switch CPR Rescuers
During CPR, it is important for rescuers to maintain effective chest compressions to ensure blood flow to the brain and vital organs. Rescuers should switch positions about every 2 minutes (option C), as this allows for the performance of high-quality compressions while minimizing fatigue.
Switching at this interval helps maintain the compression rate (100-120 compressions per minute) and ensures that compressions are administered effectively without interruption.
Here are the critical reasons for switching:
- Fatigue Management: Continuous high-quality compressions are essential, and rescuers can tire quickly.
- Effective Compression Depth: Proper technique requires deep compressions (at least 5 cm), which may suffer if a rescuer is fatigued.
- Prevention of Errors: Regularly switching reduces the chances of mistakes in technique or rhythm.
Rescuers should never hesitate to switch if one feels fatigued or if at least 2 minutes have passed since the last switch.
