life-sustaining treatment

Definition from Nolo’s Plain-English Law Dictionary

Medical procedures that would only prolong the process of dying or sustain a condition of permanent unconsciousness. A patient who is receiving life-sustaining treatment will die soon, whether or not treatment is administered. Life-sustaining treatment may include a respirator, cardiopulmonary resuscitation (CPR), dialysis, surgery, and other medical procedures.
