A DNR/DNI, or Do Not Resuscitate/Do Not Intubate order, is a written order from a doctor that resuscitation should not be attempted if a person suffers cardiac or respiratory arrest. This is sometimes known as a no-code order. Such an order may be instituted on the basis of an advance directive from a person, or from someone entitled to make decisions on their behalf, such as a health-care proxy; in some jurisdictions, such orders can also be instituted on the basis of a physician's own initiative, usually when resuscitation would not alter the ultimate outcome of a disease.
