How often should rescuers switch positions during CPR to avoid fatigue?

Switching rescuers every 2 minutes during CPR is crucial to maintain high-quality chest compressions and reduce the likelihood of fatigue. Research has shown that after about 2 minutes of continuous chest compressions, the quality begins to decline as the rescuer tires. Fatigue can lead to inadequate depth of compressions, insufficient rate, and interruptions, all of which can negatively impact the chances of patient survival. By changing positions every 2 minutes, rescuers can ensure that compressions remain consistent and effective, maximizing blood flow to vital organs during resuscitation efforts.

Regular switches not only help prevent exhaustion but also allow for a moment for the incoming rescuer to regain composure before taking over the compressions, further supporting the efficiency of the resuscitation efforts.
