What is the function of a PEG tube?

A PEG tube, or percutaneous endoscopic gastrostomy tube, is specifically designed for providing enteral feeding directly into a patient's stomach. This type of feeding is essential for individuals who cannot ingest food orally due to various medical conditions, such as swallowing difficulties or neurological disorders. The tube allows for nutrition to be delivered in liquid form, ensuring that the patient receives the necessary calories and nutrients for their health and recovery.

In contrast, the other functions mentioned are not applicable to a PEG tube. Intravenous fluids are typically administered through a different type of access, such as an IV line. While PEG tubes can indirectly support medication administration, their primary purpose centers around nutrition rather than being a primary medication route. Aspiration involves the removal of fluids or secretions and is usually achieved with different devices or methods, which also does not align with the fundamental function of a PEG tube. Therefore, providing enteral feeding is the core role of a PEG tube.
