How often should you re-check for breathing and pulse during CPR?

Re-checking for breathing and pulse every 2 minutes during CPR is crucial for ensuring the effectiveness of the resuscitation efforts. This timeframe allows for a thorough assessment of the victim's condition without unnecessarily interrupting chest compressions, which are vital for maintaining blood circulation. Frequent reassessments also help respond appropriately to any changes in the victim's status, such as a return of spontaneous breathing or pulse, enabling a switch to post-resuscitation care promptly.

In contrast, intervals that are too short, such as every minute, could disrupt the continuity of compressions and be counterproductive, while longer intervals, such as every 5 or 10 minutes, may delay critical decision-making and intervention, potentially jeopardizing the victim’s chances of survival. Thus, the 2-minute interval strikes a balance between effective CPR and timely assessments.
