Yes, yes, yes,yes, yes,yes,yes,yes..
I don't think we are talking about "Keeping people alive" specifically for organs. Once a person has been pronounced dead there ia a relatively short "window" for the harvesting of organs/skin/retinas etc. So once a family have said their goodbyes, the life supprt system can be turned off and the first steps taken to saving 4 or more lives and vastly improving the quality of life of others. Why is this "spooky"?
Of course the patient is not conscious and at least 2 doctors have to certify the patient brain dead. Organ donors and recipients cannot be in the same hospital so there is absolutely no possibility of "dodgy" dealing. People leave their material goods to their loved ones when they die - is there no greater gift than to save other lives by organ donation? Forgive me for sounding so emphatic, but I would not have had my dear husband for the last 15 years of someone somewhere had not signed their donor card. I have also spoken with the parents of a young woman who died of a brain haemmorrhage and who, when they met my daughters and me (in the relatives' room of that same ITU I refer to below) who said that having seen the "other side" of organ donation, were more certain than ever that it was what their daughter wanted.
Despite the lack of consciousness, the patient is treated with the utmost care and respect - I have seen this, I have seen a patient being washed and dried, have her hair combed, be spoken to in loving and caring terms by the ITU staff.
