Yes. I agree. But since mean intrathoracic pressure is normally negative, it does demonstrate that normal ventilatory mechanics can pump a fair amount of air in there, even in non-traumatic situations and where mechanical ventilation isn't being used. As we've already agreed, tension pneumothorax is generall rare in ANY situation.
