She spoke the lines aloud to herself over and over again as the constriction that was developing in her chest grew more apparent.
She tilted her head forward and raised her chin as she felt the heat in her eyes and the tightness in her chest. She also felt the need to breathe deeply. Additionally, she was aware of the tightening in her chest.
Once she had begun coughing, it was difficult for her to stop, and it was even more difficult for her to restore her normal breathing pattern. She was having some difficulties.
Her chest continued to get more constricted, and she coughed as the effort necessary to breathe grew more obvious. She also complained that she was having trouble breathing.
Because of this, she was unable to breathe at all while simultaneously bringing her arm closer to her nose. This was a direct consequence of the situation.
