Why is it important to monitor a casualty’s pulse?

Monitoring a casualty's pulse is crucial because it provides valuable information about blood circulation. The pulse reflects the heartbeat and can indicate the efficiency of the heart in pumping blood throughout the body. This is particularly important in assessing the circulatory system's status, as changes in the pulse can signal issues such as shock or significant blood loss. A strong, steady pulse suggests good circulation, while a weak or rapid pulse may indicate that the body is not maintaining adequate blood flow to vital organs. Therefore, evaluating the pulse is essential for understanding the patient's overall condition and determining the appropriate steps in providing care.
