Q

A 20-year-old female has called 911 for chest pain. On scene you ifnd that she has shallow breathing with an SpO2 reading of 91% on room air. She states she was in a car crash yesterday and diagnosed in the hospital with broken ribs. She says that her pain is right where the ribs are broken and rates it a 10/10. Breath sounds are prsent bilaterally. In this situation, the EMT should attribute the hypoxia to which of the following?
