I was moments away from death. The oxygen in my blood stream was starting to expire.
In reaction, my diaphragm flattened, almost instinctively. The simultaneous contraction of my external intercostal muscles forced my lungs to expand. My ribs elevated, extending the length of my thorax.
All this action, seemingly involuntary, but triggered by long forgotten impulses, had decreased my internal intrapulmonary pressure. My body had established a new pressure gradient from the outer atmosphere to my alveoli, causing air to be sucked inwards.
I had once again successfully executed the carefully calibrated intake of oxygen and nitrogen into my lungs.
