Which of the following word(s) are correct to use when speaking of organ donation?

Mechanical support or ventilator support-when someone dies, families do not think of their loved one as a cadaver we use the word loved ones when speaking about donors. the word recover is used to describe the surgical removal of organs. the word harvest is found offensive to some and not used. when a person is dead, because their brain has ceased functioning, they are still on a ventilator or mechanical support which is articially keeping their heart still beating. people mistakenly call this life support - but there is no life . once brain dead, a person is dead and there life is not being supported even though their heart is articially beating.
