When checking for pulse in an infant, which pulse should you assess?

When assessing the pulse in an infant, the brachial pulse is the appropriate choice due to its reliability and accessibility in this population. The brachial pulse can be found on the inner aspect of the upper arm between the biceps and triceps muscles, making it easier to locate in infants, particularly in emergencies or situations where rapid assessment is necessary.

The radial pulse, while commonly assessed in older children and adults, is often not palpable in infants due to their smaller size and the location of anatomical structures. The carotid pulse can be used; however, it's typically not the first choice in infants, as it can be more challenging and is less accessible without proper technique. The femoral pulse, while also an option for assessing circulation, is not as practical for quick checks in infants and is often reserved for specific situations such as severe trauma. Thus, the brachial pulse is favored for routine assessments in this age group.
