Viva 5

A 26 year old male is a passenger in a high speed motor vehicle crash. At the scene his Glasgow coma score is 3 and he is intubated by paramedics and transferred to your hospital. In the emergency room, clinical assessment and radiological investigations are consistent with an  isolated severe traumatic brain injury. He is transferred to the ICU.

The rest of the questions focussed on the evidence based approach to ICP and CPP

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.
