The fact that they don't have ID on this patient yet means that various decisions usually dependent on standard cost-benefit calculations need to be improvised; there's a lot of people who could improvise them but the one person with the job is the hospital's chief investment officer. They snap off some financial figures that almost certainly make sense, and double-check with the tech setting up Complicated Patient Intake to make sure that the retinal ID machine is being moved there and IDing the patient will be treated as a priority - at this point they don't even know if they're supposed to be cryosuspending them rather than risk any brain damage or attempt an awakening, the latter is more probable by around 10:1 but they don't want to transgress the patient's instructions if it's the former.
Personnel doublechecks to verify their memory that Merrin actually does have certs on immediate stabilization, or emergency rewarming if that's the treatment plan. (Obviously Merrin could also point this out, if there was an error, but Personnel is the one person whose job that is.) If the plan shifts to doing cryo from this starting temperature, that's going to take protocol that nobody here has memorized, but Merrin still looks probably best-qualified to implement whatever treatment plan the conditional-policy-prediction-markets say has the best chance of a good cryo outcome; it'll be a variation on cryo-from-28C which Merrin does have practiced.
