PPN

A form of short-term nutritional support that is given directly into the bloodstream through a catheter placed into a vein. PPN bypasses the digestive system and may be given when a person has a disease or condition that affects their ability to absorb nutrients through the digestive system. PPN is supplemental nutrition that is given when a person cannot get enough calories or the right amount of nutrients that their body needs from the food they are eating. Also called partial parenteral nutrition.
