I have been NPO since the operation.” Jon Reiner, “The Man Who Couldn't Eat,” Esquire (August 17, 2009) SEE MORE EXAMPLES Who uses NPO? NPO is used by nurses and doctors in medical environments, in order to identify and list patients who should not receive fluid or solids by mouth. Patients are listed as NPO when they are scheduled for surgery, since medical recommendations are for a patient to eat and drink nothing by mouth for a period of time before the operation. This was historically ordered through the phrase NPO at (or past) midnight, but more recently NPO followed by a specified timeframe appropriate for the patient. An NPO instruction may be called for in other medical cases, such as bowel obstruction, gastrointestinal bleeding, or nasogastric or intestinal tube feeding. In cases where a patient is likely to resist or forget the NPO order, such as when the patient has dementia, medical professionals will often use the NPO phrase as a noun, or an attribution of the person’s identity. For example, “Don’t give pudding to Tom, he’s an NPO.” This labeling is often viewed negatively by the patient and family of patient. Patients can also be NPO ahead of a surgery, which they often use in discussion of the difficulty of not eating or drinking for an extended period of time. NPO is also an unrelated abbreviation for nonprofit organization.
