An IV pump is a medical device used to deliver fluids, medications, and nutrients directly into a patient's bloodstream through an intravenous (IV) line. It allows for precise control over the flow rate and dosage, ensuring that patients receive the correct amount of treatment over a specified period. These pumps are commonly used in hospitals and clinics, especially for patients who require continuous medication or hydration. They can be programmed to deliver different types of fluids, including saline, antibiotics, and chemotherapy, making them essential tools in modern medical care.
