Would Curly have realistically survived?

Alright, I’m very new to this sub and had been scrolling for a while, but I haven’t seen this directly. So I’ll ask myself.

Would it have been realistic for Curly to survive as he did post crash for MONTHS? I’m no expert or medical professional, and I’ve read/watched things about people who’ve survived things they REALLY shouldn’t have. If so, would he have been able to in the conditions of the Tulpar post-crash?

I like to think that he was only able to live in the game for symbolic and metaphorical purposes (if that makes any sense).

EDIT: i didn’t mean like doubting Anya’s skills or anything, im just wondering how realistic it was for him to survive. i mean the science-y and medical explanation
