If someone is exercising and breathing heavily, and they are exerting themselves to the point they pass out, will they continue to breathe heavy or will their breathing return to normal?

Answer 1

If they’re breathing heavily from exercise they’ll keep doing so because they have a physiological need for oxygen and the autonomic nervous system controls that. If they are breathing heavily for another reason, like they’re scared or panicking, then their breathing will quickly return to normal after they pass out because the reason for the heavy breathing has ended
