Vascular access refers to the process of gaining entry to the bloodstream through a vein or artery. This is essential for various medical procedures, such as administering medications, drawing blood, or providing fluids. Common methods include using a venous catheter or a central line, which are inserted into a vein for easy access. Proper vascular access is crucial for patient care, as it ensures that treatments can be delivered effectively and safely. Healthcare professionals must follow strict protocols to minimize risks, such as infection or complications, associated with these procedures.
