What pulse should be assessed in an infant?

In infants, the brachial pulse is considered the most effective site for pulse assessment. This pulse is located centrally in the arm, and it is easily accessible due to the relatively small size of an infant. The brachial artery runs along the inner side of the upper arm, making it a preferred choice since it offers a reliable way to evaluate circulation and assess heart rate in such young patients.

Using the brachial pulse is especially important in emergencies or clinical assessments, as it allows for a quick and accurate measure of the infant’s cardiovascular status. The carotid pulse, while important in older patients, is difficult to palpate in infants due to their anatomical size and positioning. The radial pulse is typically assessed in older children and adults because by that stage, it is more prominent, but in infants, it may be too weak or difficult to feel. The posterior tibial pulse is typically assessed in lower extremities and is not as practical for evaluating pulse in infants where the brachial pulse is a clearer indicator of circulation.
