Intravenous (IV) therapy is a medical treatment that delivers fluids, medications, or nutrients directly into a patient's bloodstream through a thin tube called a catheter. This method allows for quick absorption and is often used in hospitals for patients who cannot take medications orally or need immediate treatment. IV therapy can be used for various purposes, including hydration, pain management, and administering antibiotics. It is commonly employed in emergency situations, surgeries, and for patients with chronic illnesses. Medical professionals monitor the process to ensure safety and effectiveness throughout the treatment.
