Clinical case.
“A previously well fully immunized 6 year old girl is admitted to your ICU in a regional hospital with a 5 day history of high fevers, and a blanching macular rash. Twenty four hours prior to admission, she passed loose stools on four occasions with no obvious blood or mucus in the stool. On examination she is tachycardic with warm peripheries with an unrecordable blood pressure.” Candidates were asked to review an ECG, a CXR and to discuss potential aetiologies.
Twenty out of twenty-seven candidates passed this station.

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.
