For everyone saying you wouldn’t give blood and organs to a dead person, medicine is getting much better than it was. A pig was basically brought back to life after being dead for two hours.

When we think of a person dying, we think their heart isn’t beating, but a lot of times it’s basically just “fluttering.” If we can restore blood flow to it by artificially pumping their blood and using a gas exchanger to oxygenate it, we can get adequate blood flow to it. This machine exists and is used for some surgeries. Then in theory you can defibrillate it. The heart can function if a significant portion of the cells are dead.

When blood flow is stopped to the brain for over 5 minutes, approximately, the cells start dying. Again, the brain can still function if a large portion of it is dead.

What a lot of people said regarding the finite supply of blood and organs holds true. There are only so much, and so many, of each. These are reserved for those that truly need them. If someone drinks alcohol, smokes, or uses other drugs they can be disqualified. The same holds true for people with unhealthy life choices. Also, the number of skilled surgeons who can perform these operations is limited. This is compounded by the fact if we started doing this, the system will become overburdened. Something people don’t take into account is when people have this option, they will take it, and not take care of themselves.

If you look at regenerative medicine, it is improving. This would probably be what you want to look at for cases of old age and illness. Regarding trauma, restoring blood flow and giving a transfusion would probably be the better way to go if blood supply wasn’t an issue. There aren’t enough blood donors so this is a major issue. People are constantly working on trying to improve this with artificial blood, or creating transgenic animals with compatible blood.

If this really concerns you, go to your local Red Cross or other blood bank and donate as soon as possible. See if they offer apheresis. You can do this more often and help more people.
