What vital sign is typically assessed to check for circulation?

The assessment of pulse rate is crucial for evaluating circulation. The pulse reflects the rhythm and strength of the heartbeats, providing insight into how effectively blood is being pumped throughout the body. When checking circulation, practitioners often feel for a pulse at various points on the body, such as the wrist or neck, to determine whether blood is flowing adequately. A strong and steady pulse indicates good circulation, while a weak or irregular pulse may suggest inadequate blood flow or other circulatory issues.

In contrast, while respiratory rate measures how often a person breathes and is important for assessing ventilation, it does not directly indicate circulation. Blood oxygen level measures the amount of oxygen in the blood but does not reflect how well blood is circulating. Body temperature can indicate infection or other metabolic processes but is not a direct measure of circulation either. Thus, pulse rate is the most relevant vital sign to assess circulation effectively.
