First, helium is an asphyxiant. If you ingest large ammounts of it, your body will have less oxygen in the system.

Second (how Angus was killed), Angus ingested helium from a pressurized can. Helium entered in his body with such a pressure that lungs blew up like a balloon when you fill it too much.
