What lab findings might accompany circulatory overload?

Fluid intake greater than urinary output is a key indicator of circulatory overload. This condition occurs when there is an excessive volume of fluid in the circulatory system, often as a result of intravenous (IV) fluid administration that exceeds the body's ability to manage or excrete it. When assessing a patient, if the amount of fluid administered significantly outweighs the urine output, it suggests that the kidneys may be unable to effectively eliminate the excess fluid, leading to symptoms associated with overload such as hypertension, edema, and respiratory distress. Therefore, monitoring the balance between fluid intake and output is crucial in identifying and managing circulatory overload.
