He could be a podiatrist...
I remember a call with a cardiac pt, her son showed up and we explained-- in layman's terms-- what was happening. He goes, "I'm a doctor, just tell me what's up." So, we show him the 12-lead EKG and say "check out the elevations in five & six". Right away he goes, "um, I'm a actually a psychologist, sorry."
Back to the tourniquet issue... I can't speak for what a PA or MD would do, but current practice (for arterial bleeding) is direct pressure and then straight to tourniquet if that doesn't work. I could care less what Silver thinks of EMT/paramedics-- if someone gets shot outside of an ER, then it's prehospital and therefore our turf. Not trying to start a pissing contest here, but being a good ER doc doesn't necessarily translate to providing good prehospital care. What the average Joe at Koko Head will have in his IFAK is closer to what we carry on the rig, and any advice that any HM/68W/MICT has to offer is completely relevant.
I can't tell you the number of calls where I'd have some person come up and say "I'm a doctor" and start giving orders. Occasionally, it would be someone with some relevant experience, but I always found that it was those guys that "offered" to help rather than tried to commandeer the scene. Most of the folks that tried that were completely out of their element (optometrist, third year medical resident, dermatologist, etc.). I'd usually tell them we were alright and operating off our protocols, but with the extra pushy ones I'd simply ask for their name and proof of professional licensure, and then explain that they could, if they wanted, assume full and complete responsibility for the scene, including associated liability if they wanted. None ever took me up on the offer. I have even had the cops remove these self-professed "doctors" from the scene for me if they continued to be a PIA. I love it when you watch them drug away by the cops screaming "...but I'm a doctor...."
As for his grammar and syntax, that and his completely dated advice pegged him immediately as someone who didn't have the background he claimed....hey, maybe he can be our very own version of the mall ninja. You know, the ninja doc.....wonder when he'll start advocating for intra-cardiac epinephrine and massive bicarb administration for arrests?
