XVII Glossary

Enteral nutrition (EN): Nutrition provided directly into the gastrointestinal (GI) tract through an enteral tube that bypasses the oral cavity.

Gastric residual volume (GRV): Stomach contents aspirated with a 60-mL syringe, typically performed for patients receiving enteral feeding to assess aspiration risk with associated interventions such as slowing or stopping tube feeding. GRVs in the range of 200–500 mL should raise concern and lead to the implementation of measures to reduce risk of aspiration.

Stomach decompression: Using suctioning through a nasogastric tube to remove the contents of the stomach.
