I technically understand how the brain could have been swelling or bleeding over the time span, but what gets me is the way other people survive such extreme traumas like a gunshot to the head or a Phineas Gage type of injury... http://en.wikipedia.org/wiki/File:Phineas_Gage_CGI.jpg
ETA: my post reads with a calloused tone, but that's really not how I typed it to sound. More like a shocked train of thought kind of thing. Her poor boys...

The problem with this story is that we have very few details. From the history given of the incident, she likely suffered from a epidural hematoma. The classic story is that the patient has a blow to the head, may or may not lose consciousness, then feels fine. Hours later if the patient is not treated, they lose consciousness again and die. The bleeding continues from the time of injury until it reaches a point that the pressure on the brain overrides the brains ability to compensate for this pressure change. The patient then herniates brain tissue out of the cranial vault and puts pressure on the brain stem which stops the patient from breathing and they die.
Other penetrating injuries, like Phineas Gage, will produce local injury which may or may not be fatal depending on the importance of the injured brain to basic life functions. There are large areas of the brain that are NOT essential to life. You may end up with memory, speech or motor problems, but if you can breath, you live. Richardson was just unlucky enough to break her skull and tear an artery which caused the fatal bleeding.
This is a very basic review of brain injury. There are a lot of other factors involved in outcomes, but they are more predictable than you think.
What is unfortunate is that if Natasha Richardson had been treated immediately, she may not have died. We'll have to wait for more details to know for sure.
My heart goes out to her family.
