A previously well 33-year-old male (90 kg, 182 cm tall) has been admitted to your ICU following a hanging attempt. The paramedics were only able to pass a standard size 6 endotracheal tube (ETT).
The ETT was secured at 24 cm at the teeth, and shortened to a total length of 27 cm, in keeping with local pre-hospital transport policy.
(This viva dealt with a difficult airway.)
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.
