Which artery is typically used to measure blood pressure in adults?

The brachial artery is typically used to measure blood pressure in adults because it is centrally located and provides a reliable reading that reflects systemic arterial pressure. Located in the upper arm, it is easily accessible and commonly used in conjunction with a sphygmomanometer (blood pressure cuff) during clinical assessments.

Using the brachial artery is particularly advantageous because it is large enough to accommodate a blood pressure cuff and deep enough to reduce the chances of interference from surface structures. The position of the brachial artery also allows for an accurate measurement that correlates well with the pressures in the heart and major arteries, making it the standard site for this measurement in most healthcare settings.

Other arteries, while they can provide a pulse, are not commonly used for blood pressure measurement. The radial artery, for instance, is frequently used for pulse assessment but does not provide as reliable a blood pressure measurement as the brachial artery. The carotid artery, though important for assessing central circulation, is not ideal for blood pressure measurement due to its close proximity to the heart and potential for affecting readings based on position. The femoral artery is considered for use in emergencies or specific situations but is not the standard site for routine blood pressure measurements.
