I may be wrong, but im pretty the sure system that helps you breathe is called "life support" i think it runs your heart for you and helps you breathe.
the risks the diver most was holding their breathe using nose clips for long time
A snorkel longer than 1 meter (about 3 feet) will make it impossible to breathe as the water pressure on the chest will make it impossible for him to expand his chest and fill his lungs. A diver below this depth will need to breathe pressurised air from a tank.
