What does 'NPO' stand for, and what does it imply?

'NPO' stands for 'Nil Per Os,' which is a Latin phrase meaning "nothing by mouth." This term is commonly used in medical settings to indicate that a patient should not consume any food or drink orally. The implication of being NPO is critical in various clinical situations, especially before surgeries or certain diagnostic tests, as the presence of food or liquid in the stomach could interfere with procedures or anesthesia.

Understanding the concept of NPO is crucial for ensuring patient safety and proper care. Following NPO orders helps in minimizing the risk of aspiration during procedures and enables healthcare providers to prepare patients appropriately for various interventions. In addition, healthcare teams rely on this directive for the management of nutritional needs and fluid intake in a hospital setting.
