What should rescuers do if there are multiple rescuers available?

When multiple rescuers are present, it is essential for them to rotate every 2 minutes. This practice is guided by the principle that high-quality CPR requires significant physical effort, and maintaining optimal performance is crucial for the efficacy of the resuscitation effort. After around 2 minutes of continuous compressions, individuals can become fatigued, which may lead to decreased effectiveness in delivering compressions both in terms of rate and depth.

Rotating rescuers every 2 minutes helps to ensure that one person is always providing high-quality compressions while the others can support them by managing the airway, providing rescue breaths if trained to do so, and monitoring the patient's condition. This structured approach helps maintain the quality of care provided to the patient and enhances the likelihood of a successful outcome.

In contrast, performing compressions continuously without rotation can lead to fatigue and compromised compressions, which can be detrimental to the patient. While it is important to always have someone doing CPR, there is a systematic and effective way to ensure that the CPR provided is of the highest quality by rotating responsibilities systematically.
