While I have no idea if OP was being hyperbolic, EMS level 3 could be shoved into 8 weeks if you were motivated, its only like 20 credit hours plus practical field work.
Not intentionally. I can't find the source right now, but I recall an article mentioning medical practitioners being trained for massive natural disasters (e.g., Haiti) in a matter of weeks.
Obviously these people were trained to perform a very narrow range of tasks, not unlike a coding bootcamp student would learn Rails and be virtually ineffective with just about anything else.
Even the article conceded these practitioners weren't ready to be full-time doctors, but the point was that they could do something in the field without years and years of formal education..
In more common terms, they'd be medics. That's a bit broad, as some medics are far more capable than others, but for those who are primarily intended to provide first aid (rather than long term care or surgery or diagnostics), they're typically called medics. And 8 weeks is enough time to train someone in the basics of that field (especially 8 weeks of full-time training).
