Fluid management is the process of monitoring and controlling the amount of fluids that enter and leave the body. It is an important part of medical care, especially for patients who are critically ill or have chronic conditions. Fluid management involves the use of intravenous (IV) fluids, medications, and nutrition to maintain the body's fluid balance. It also includes monitoring the patient's vital signs, such as blood pressure, heart rate, and urine output, to ensure that the body is receiving the right amount of fluids.
