Remember
Robocop (1987), where Murphy gets shot multiple times (hand obliterated, bullet to the skull) execution style by the Bad Guys™ ... and the medical teams STILL manage to save his life (after which he gets cyborged into becoming Robocop)?
If you ever listen to the director's commentary track for that movie, during those scenes the commentary is talking about how the movie makers were asking EMTs and emergency room personnel if what they were wanting to do on screen was even plausible/possible. The medical people were telling the filmmakers, "yeah, we see that kind of trauma A LOT, and it's survivable with medical attention."
Even in the mid-1980s, the filmmakers worried that what they wanted to show happening to Murphy was comical to the point of being implausible. But when they talked to actual medical trauma professionals, they got told that what they were wanting to film happening to Murphy wasn't even the most extreme stuff that the emergency room people had been able to save people from.
Granted, the survivors were "never the same again, afterwards" ... but they LIVED.
And that was with the medical technology and techniques available
~40 years ago.
Medical technology and techniques have only gotten BETTER since then.
