A 60 year old man has been transferred to your ICU from another hospital ICU, where he had been admitted 10 days ago with severe pancreatitis and requiring mechanical ventilation. His oral intake was said to be poor during the week leading up to that hospital admission.

1. How would you assess his nutritional state?

The rest of the questions focussed on the route of administration of feeds, calculation of caloric requirements, and the role of immunonutrition.

Disclaimer: the viva stem above is the original CICM stem, acquired from their publicly available past papers. However, because the college do not make the rest of the viva text or marking criteria available, the rest has been confabulated. It sounds like a plausible viva and it can be used for the purpose of practice, but all should be aware that it does not represent the "true" canonical CICM viva station.
