If anyone can shout that they're not breathing, they're making a good job of not breathing. Anyone who can't breathe, can't speak let alone shout.
Try speaking when your throat's constricted.

"The ability to speak does not mean the patient is without danger," said Dr. Mariell Jessup, chief science and medical officer of the American Heart Association.
"To speak, you only have to move air through the upper airways and the vocal cords, a very small amount," and that does not mean that enough air is getting down into the lungs where it can supply the rest of the body with oxygen, said Dr. Gary Weissman, a lung specialist at the University of Pennsylvania.
