Setting: Modern day, in a somewhat isolated forest. But not too isolated.
Research: I tried googling "shallow breathing and fainting", "breathing after fainting" and tried the same for videos, but all I got was shallow breathing as a CAUSE of fainting, and nothing on what happens afterwards, or videos of people breathing rapidly to induce fainting. I also googled how binding affects breathing.
The scenario: A trans* guy wearing really tight binding gets in a fight in a forest, in the process gets worked up that his binding is dangerously restricting his breathing (i.e. he can't breath deeply at all, and he breathes rappidly and shallowly instead). He faints, from this and from his injuries, and his opponent loosens his binding, but what I want to know is 1) Would fainting affect how he breaths? Will he breath at all? and 2) After his binding is loosened, how will his breathing recover?
Other relevant details: His opponent doesn't know he's trans* and doesn't know much in the way of first aid, but has called emergency services. Neither expected the fight to get that serious. He hasn't hit his head, and his opponent found out about and loosened his binding really quick, so the damage would be pretty minimal.
