“The brain stem controls all the essential functions that keep us alive, most importantly our consciousness/awareness, our ability to breathe and the regulation of our heart and blood pressure. Once the brain stem has died it cannot recover and no treatment can reverse this.” “When death has been diagnosed by the methods to be described, the patient is dead even though respiration and circulation can be artificially maintained successfully for a limited period of time. The appropriate course of action is then to consider withdrawal of mechanical respiratory support, the ethical justification for which has passed, and to allow the heart to stop. This imposes an unnecessary and distressing vigil on the relatives, partners and carers, who should be kept fully informed by the local care team of the diagnosis, the inevitable outcome and the likely sequence of events.”
“In contrast to issues concerning the medical treatment of the living, whether they be children or adults who lack capacity, where the best interests of the individual will determine the outcome, where a person is dead, the question of best interests is, tragically, no longer relevant.”
