Peripheral venous catheters (PVCs) are small, flexible tubes inserted into a vein, usually in the arm or hand. They are used to deliver medications, fluids, and nutrients directly into the bloodstream. PVCs are commonly employed in hospitals and clinics for patients requiring intravenous therapy. The insertion of a PVC is a quick procedure performed by trained healthcare professionals. These catheters can remain in place for several days, depending on the patient's needs and the condition of the insertion site. Proper care and monitoring are essential to prevent complications such as infection or phlebitis.
