Kinda sounds like you don't have an answer.
Sure, if your bestie is having a tough time then of course you'll talk to them and do whatever it takes not to call EMS.
If it's a "casual acquaintance" as I said your options kinda diminish.
I called EMS for my neighbor once. A few days later his mother came to thank me profusely.
I'm not in the US though so things work a bit differently here.
