I am an EMT, it used to really get to my ego to be in a public place when an annoucement is made over the public annoucement "if there is a doctor in the house please report to...". I usually show up finding no doc there or nearby annoucing myself as a firefighter. How about "medical professional?"
It's still a bit of my ego I guess, and people I'm sure mean well. 
I recently was volunteering at a location where I am also a Reiki provider, but was simply giving holiday help. That location also hosts readers, psychics, and other energy healers. 
I digress, I was volunteering when someone came to me saying someone needs "emergency Reiki". Huh? Emergency Reiki? "How about a Doctor." I asked myself in jest. It was a fellow Lightworker that had tweaked herself.
Having no opportunity to cleanse the room or any of the cool formal stuff I was trained to do, I just had to "go at it". I said a brief prayer and got her breathing under control, and mustered the Reiki guides together. To make it more interesting, for the moment she could only stand up. 
All the things I've learned and read came back to me that there really is no protocol. There is only Reiki, ONLY REIKI. Then I related to an article that I have recently written for RJ on Reiki in the streets. Wow! I suppose I really was listening, really trusting and really letting Source and the Reiki guides do what they do. We are just the contact point, the conduit. I do however feel healed whenever I help someone in need. Reiki floods my soul and brings me incredible joy.
So next time you see an emergency, or hear "is there a Doctor in the house", no matter your profession otherwise, send Reiki and love to their moment of great need. It may be a lifesaver.
Peace! Brian
