The body is kept alive by a multitude of drugs, on ventilator support. Testing is done, such as echocardiogram and bronchoscopy, to verify if the heart and/or lungs are suitable for donation. For example, we had a young female MVA that they were not able to harvest the heart from because her heart had apparantly suffered trauma as well. Her ejection fraction was between 5-10%.
There IS testing done that shows if the patient is brain dead or not before organ donation is brought up to the family. One of these is an apnea test. The ventilator will be stopped and the patient observed for any signs of spontaneous respirations for a matter of minutes...NOT exactly the favorite of conclusive brain death tests for a critical body you're trying to keep alive. There is also EEG for wave activity and blood-flow scan done in radiology to determine if the brain is getting any blood flow at all. When a patient has a severe head injury, there can be so much pressure built up in the brain that prevents further blood flow and oxygenation. This is often how brain injured patients become brain-dead patients. The built up pressure can also cause brain-stem herniation which also results in brain death.
It is unfortunate that so many in the public, even other nurses, don't have a complete understanding of the process. That is why some assume that we are "killing people for their organs". That is not the case. These patients are already technically DEAD. If you are brain dead, you are dead. If these patients were not organ donors and simply taken off the ventilator, their bodies would die naturally in a matter of minutes due to lack of oxygen. There is no command from the brain to tell the body to breathe.
Thank you fellow ICU nurse!
Just to re-iterate the most important point of your post:
BRAIN DEAD = DEAD
This concept is very difficult for people to grasp, I know it's difficult to understand that if Momma is breathing on the vent and has a heartbeat, how can she be dead? But we do extensive testing to validate brain death and it must be 100% conclusive for the patient to be declared.

Just reading this thread shows how many misconceptions there are about organ donation. Having cared for many donors and potential donors, I can tell you that it is a grueling, time-consuming process, requiring the highest level of ICU nursing care available.
Please educate yourselves. Even if you don't support organ donation, you will at least be able to clear up common misconceptions when confronted with them in your nursing practice.
