Has anyone ever held their breath and passed out unconscious?
Because this website says that once someone is unconscious, they will stop breathing. If there are any survivors of breath-hold unconsciousness then please post here to refute it.
Basically it says they wont start breathing again.
''It is conceivable that the hypoxia (low oxygen state) led to loss of consciousness, which in turn would cause total relaxation of the muscles, suspending respiration. If the lung volume at that time was greater than the expiratory reserve volume of the lungs under those conditions, air would be expelled passively.
The effect of severe hypoxia would then prevent the effort to inhale, which would be expected after expiration, and in the next few seconds death would occur.''
