Iowa Code § 702.8
"Death" means the condition determined by the following standard: A person will be considered dead if in the announced opinion of a physician licensed pursuant to chapter 148, a physician assistant licensed pursuant to chapter 148C, or a registered nurse or a licensed practical nurse licensed pursuant to chapter 152, based on ordinary standards of medical practice, that person has experienced an irreversible cessation of spontaneous respiratory and circulatory functions. In the event that artificial means of support preclude a determination that these functions have ceased, a person will be considered dead if in the announced opinion of two physicians, based on ordinary standards of medical practice, that person has experienced an irreversible cessation of spontaneous brain functions. Death will have occurred at the time when the relevant functions ceased.
