My mistake there. I was using the copy of SOP that I have on my HDD from before I moved. It had PTLA, EOA, Combi, and LMA. Looks like they finally took out EOA and added King (which was not allowed when I left NM earlier this year by any service. The date on the new ones on the website say 2008 but I wasn't certified until Jan 2008 and we were flat out told in all my education following that that Kings were not allowed in NM at that point. I dunno. I'll just smile and nod and stand corrected.
EDIT: Looking over the SOP from NMEMS.org, it looks like EOA might still technically be in scope since it can be classified as a supraglottic airway device. My first service I worked at still had a few of those laying around, fun to play with on a dummy
