Sharon "gets the wind knocked out of her" during a skiing accident in which she attempted a jump and landed hard on her feet before tumbling over. She is conscious but breathing is labored, and she complains of pain and shortness of breath. The first aid-trained ski patrolman that comes to her aid determines that Sharon has no broken bones, nor is CNS injury likely. He places tiny tubes at her
nostrils that blow air (with higher than normal percentage of oxygen) into her nose then places her on the snowmobile, and takes her to the first aid tent. Why is Sharon's breathing labored? How does the high-oxygen air help her condition? What will be an ideal response?
