How frequently should compressions be switched according to high-performance CPR guidelines?

The correct frequency for switching compressions in high-performance CPR is every two minutes. This guideline is based on the recognition that high-quality chest compressions are crucial for effective cardiac resuscitation. Continuous compressions can lead to fatigue for the rescuer, decreasing the quality of chest compressions over time.

By switching providers every two minutes, it allows one rescuer to take over while the other can rest briefly, ensuring that the quality and rate of compressions remain consistent and effective. This strategy helps maintain the compressions at the recommended depth and rate, which is essential for maximizing blood flow to vital organs.

Additionally, switching providers every two minutes aligns with the recommended rhythm and timing of the CPR process, where assessments and interventions can also occur at logical intervals without interrupting the flow of care.
