Question: does the baby survive in the movie hours

Answer: Yes, Nolan is now so exhausted he cannot crank it with his hand any longer. Nolan has to use both his hands to slowly crank the handle, but breaks it off accidentally. Nolan's attempts to fix the crank generator fails, so he gives his child mouth-to-mouth resuscitation to keep her alive. Before he can do any more, Nolan passes out from shock, stress, and exhaustion. Nolan then hears the ventilator beeping; it is running out of power. However, he is too weak to get back up. Nolan accepts that he has failed his child. But Sherlock comes to his aid and brings two paramedics with him to save Nolan, and drag him out. When Nolan wakes up, the paramedics hear his baby crying and run off to find her. Abigail has finally learned to breathe on her own. The paramedics give Nolan his baby and the two embrace, with Nolan crying tears of joy as they are brought to safety.
