Gunshot wound to ribs

Okay, so I've done some research and while I've found some things, I'm still not very comfortable in adding it to my story right now. So here's the situation:

40-year-old man shot from the back, impacting somehwere around the rib cage and he is immidiately taken to the hospital. I obviousy don't want him to die, but I don't know what would be realistic. The most I've found was on hemothorax and such, but I know that a bullet would probably cause quite a bit of damage but... I don't know. 

If anyone has some ideas, that would be lovely. Thanks so much :)
