What is the maximum time allowed for switching roles in a CPR team?

5 seconds
10 seconds
15 seconds
20 seconds

The correct answer is: 10 seconds

In a CPR team, effective teamwork is crucial for maintaining the quality of care provided to the patient. The maximum time allowed for switching roles in a CPR scenario is 10 seconds. This brief duration is essential because it minimizes the interruption in chest compressions, ensuring continuous blood flow to vital organs, particularly the heart and brain. Switching roles is important to prevent fatigue among rescuers, which can diminish the quality of chest compressions over time. By adhering to the 10-second guideline, teams can efficiently rotate roles without compromising the effectiveness of the CPR being administered. This standard is based on best practices that focus on maintaining high-quality compressions—at a depth of at least 2 inches and a rate of 100 to 120 compressions per minute—critical in improving outcomes in patients experiencing cardiac arrest.
