The question on the passage of the rescue of the crew. (Prey (2017))

Play the first time, try to pass on the best possible ending, to save as many people as possible from the crew. So in the story after the arrival of the dal, it cuts off the air in the cargo hold Sara Elazar and other survivors. The first thing I cut Dahl, restoring the air, and then his operator.
So after eliminating operator Sarah gathers all the survivors and why it is rushing to the life support, which killed most of the group, even despite the fact that the location I cleared.
Is it possible this how to avoid? Or is it all an inevitable part of the plot?
Preferably without spoilers about future events.
