first off, we are not certain that we yawn to get more oxygen although it is thought to be a possiblity and is probably one of many factors. i think we don't yawn when suffocating because gasping is a more natural reaction in an attempt to get more air and that there could be other things we might be more preocupied with when suffocating. for example, a person tied to an anchor underwater may be trying not to breathe in water and trying to untie themselves from the anchor. a person being choked may be attempting the fight off their assailant, while a person breathing in carbon monoxide may become unconscious.

A ghoulish sort of question. The situation that brings on a yawn is much different from that which is associated with suffication. The yawn is an involuntary response-just try to yawn on purpose.
