Chiropractor was reviewing game film thenIt would be a team working. Most likely EMT’s would be handling the actual compressions/bagging. They have an airway specialist to intubate. The primaries would be involved communicating care and doing a work up. The neurologist would also be checking for deficiencies as well. With that crew you can get a pretty thorough work up so the hospital knows exactly what’s coming in.
Edit* someone would also be asking the players nearby exactly what they saw happen to get a better idea.
