During infant CPR, the ideal frequency for checking the brachial pulse is every 2 minutes. This interval is a critical aspect of the assessment process during cardiopulmonary resuscitation (CPR) because it allows rescuers to regularly evaluate the effectiveness of their interventions, such as chest compressions and rescue breaths.

Checking the pulse too frequently, such as every minute or every 30 seconds, could be distracting and might disrupt the flow of CPR, which should be performed continuously to maximize the chances of restoring circulation and promoting survival. On the other hand, checking less frequently, such as every 5 minutes, may delay necessary actions and prevent timely adjustments based on the infant’s response. Therefore, checking the brachial pulse every 2 minutes strikes a balance between thoroughness and efficiency during the emergency response.
