You are the Intensivist in a tertiary metropolitan unit caring for Mr John Wilson, a previously well 45 year old man who has suffered a devastating neurological injury as a result of a subarachnoid haemorrhage. After detailed discussions with his family everyone has agreed that life sustaining measures should be withdrawn and Mr Wilson be allowed to die.
During these discussions his family raised the possibility of organ donation. At present Mr Wilson has a GCS of 4 and has spontaneous respiratory activity. You do not envisage that he is likely to progress to brain death.
You are about to enter a meeting with his partner to discuss the options.
Disclaimer: the viva stem above may be an original CICM stem, acquired from their publicly available past papers. Or, perhaps it is a slightly altered version of the original CICM stem. Or, it is a completely original viva stem, concocted by the monstrously amoral author of Deranged Physiology for nothing more than his own personal amusement. In either case, because the college do not make the main viva text or marking criteria available, almost everything here has been confabulated. It might sound like a plausible viva and it could be used for the purpose of practice, but all should be aware that it does not represent the "true" canonical CICM viva station.
