“I suspect it would take longer for someone to ‘train’ you on how to find CT scan and the ER than to figure it out yourself.”
Technically, that’s true. I’ve saved my companies many thousands of dollars by learning (by reading) equipment, processes, applications, etc., and then training co-workers. They didn’t need to hire expensive trainers.
But the hospitals, where I’d like to volunteer, have strict protocols for volunteers no matter who you are or what you’ve done. I respect that; it relieves them from possible future liability, I suppose.
If they get up to their ear lobes in blue people those protocols will go right out the window.
