I am interested in volunteering at a local amateur MMA event as a 3rd year medical student. I do have an active Advanced EMT certification, but obviously I don't have my own medical license. Can I do anything medical related for this promotion? I absolutely do not want to anything that is outside my scope as a student, but what can students actually do in an event like this? If there was a physician there who agreed to oversee what I was doing would that change what I could do?
