In an infant, which pulse is typically assessed?

In infants, the brachial pulse is the most commonly assessed pulse point. This is because it is more accessible and easier to palpate in this age group compared to other pulse sites. The brachial artery runs along the inner part of the upper arm, making it a practical choice for checking pulse in infants.

Using the brachial pulse is particularly important during emergencies or when a quick assessment is needed, as this site can provide reliable information about the infant's circulatory status. Additionally, in younger patients, especially those under one year old, other pulse sites may be less reliable due to anatomical differences and size.

For example, the radial pulse is not typically used in infants due to the smaller size of their wrists, making it difficult to palpate. The carotid pulse, while useful in adults, may not be as easily discernible in infants due to their smaller necks and the risk of damaging surrounding structures. The temporal pulse is also less frequently assessed in infants; it serves more as a location for checking pulse in adults or older children.

Using the brachial pulse ensures that healthcare providers can effectively monitor and assess the vital signs of infants in any medical situation.
