Ryan felt as if he was in a tunnel

Ryan felt as if he was in a tunnel. He knew that Caleb had been yelling something at him, but for the life of him he couldn't hear the older man any longer. Everything was muffled; sound, colors, touch – everything. Suddenly his arm felt like someone had broken it. The pain radiated up and into his chest. He couldn't breathe!

The lack of air caused him to lose control of his legs. The next thing he knew, he was looking up at the ceiling gasping for breath. Ryan could barely hear his name being shouted in the background. It was gradually getting farther and farther away until everything went silent and black.
