Firefighter Al McLeod tells CHSJ News throwing the boy over his shoulder knocked his mask off so he inhaled the same amount of smoke and carbon dioxide as the teen.
He says it's toxic gas and you only get a few breaths of that before it will kill you.
McLeod, another firefighter and the teen were all treated in hospital and released. The home is owned by a retired firefighter who was able to tell rescue crews exactly where his son was in the house.
