After her first moment of surprise, Maura was up and rushing toward where Travis lay on the floor. Knowing they were heading for the weekly picnic soon, her medical bag was on the floor next to her and she grabbed it on the way. TJ was focused on Derek for the moment and that was just as well. It let Maura get in and get a good look at Travis. Blood was blossoming on his left side and she could hear the difficulty he was having breathing before she even got the stethascope out of the bag.
"TJ, I need your hands." That brought his attention back to her immediately. "Here. Press this right here. Doug, call Robert. I need him here now!"
"He's going to be okay, right?" TJ followed directions almost automatically, clearly too worried to question her. "Maura?"
"It's a pneumothorax...His lung is partially collapsed," she explained, checking Travis' chest. "Possibly a cracked rib." She checked his pulse. "I need to relieve the breathing and get an x-ray to see how much damage there is."
