How should the CPR team coordinate the switching of compressions?

The best approach for the CPR team to coordinate the switching of compressions is by calling out "switch" at the end of the last compression cycle. This method provides a clear and audible signal that ensures all team members are aware of the transition, minimizing any interruptions in the quality of chest compressions. Clear communication is vital in a high-pressure situation like CPR to maintain effective perfusion and avoid confusion.

Using a call-out allows for synchronized changes, ensuring that one rescuer can prepare to take over while the other is completing the final compression. This strategy enhances teamwork, ensuring that compressions continue uninterrupted, which is critical for the patient’s survival.

Other methods, such as counting to three or taking turns after every five compressions, could lead to inconsistent timing and potential lapses in compressions, whereas hand signals may not be as effective in a high-stress environment where verbal cues are typically more immediately noticed.
