If it looks like she might die, maybe assist her if she's still pushing things out. I've read of people gently pushing on the belly down towards the birthing canal(kinda like a massage) and out to help her pass whatever is blocked. Keep her in very clean water to help her recover and to make sure she gets no infections, make sure she's not with any males that will harass her and not cause her to rest up either. Also see she if she wants to eat. I know my females will be VERY hungry after giving birth(mostly because that hormone kicks in that makes them not want to eat before birth) so maybe feed her some food to get her energy up again. Giving birth is very stressful for any creature.
