Organ donation is usually done from a living, but brain dead, person. There's no specific rush, the person can stay alive for a while. They are killed (controversial word there...) in order to take the donation. On a practical level, most donation comes from head injury patients, motorcycles in particular are known for providing a lot of such patients. Hypoxia (drowning) also works (sometimes) if it's long enough to kill the brain, but not the rest of the body. There aren't as many candidates for donation as you might think. There is a lot of research on how to donate from a someone with cardiac death - doing that would significantly increase the donor pool, while also removing a lot of the objections.
