Blood pressure is an important indicator of the human body's vital signs. The level of blood pressure can help determine whether the body's cardiac function, blood flow, blood volume, and vasomotor function are properly coordinated. If blood pressure is abnormally increased or decreased, it indicates that there may be some abnormality in these factors.
Long-term elevated blood pressure can cause relatively large damage to blood vessels and multiple organs throughout the body. A sudden drop in blood pressure is also highly suggestive of hypovolemia, abnormal vasodilation, and severely impaired cardiac function.
Therefore, monitoring the level of blood pressure helps to determine the health status of the human body and the changes in the condition of critically ill patients.
