For which age group would you check the brachial pulse?

The brachial pulse is the most appropriate pulse check for infants because their physiology requires a different approach than that used for older children and adults. In infants, the brachial pulse, located in the upper arm, is more accessible and can be easily palpated due to their smaller size and relatively higher body fat percentage. This makes it less effective to check for pulses in other locations like the carotid or radial pulse, which are more commonly monitored in older populations.

For children and adults, the carotid pulse is typically checked, as they possess a larger body structure where this pulse can be more palpably located. Seniors, while still requiring careful monitoring, would also benefit from checking the carotid pulse rather than the brachial pulse. Thus, utilizing the brachial pulse for infants aligns with best practices in assessing vital signs, which is critical for proper emergency response.
