According to the Cleveland Clinic, total parenteral nutrition is a method of feeding that bypasses the gastrointestinal tract to deliver nutrients directly into the bloodstream. A central venous access device, or CVAD, is the critical piece of equipment used for this process, ensuring a safe and effective delivery method for patients who cannot receive nutrition orally or enterally.

Due to its high osmolarity, total parenteral nutrition (TPN) cannot be safely administered through a standard peripheral intravenous catheter, making a central venous access device (CVAD) the required route. The concentrated nutrient solution would otherwise cause significant and rapid irritation to the smaller, more fragile peripheral veins.
