As an EMT-B I have come to realize proper BVM use, is one of the most important things I can learn. I can generally get a good seal, due to my mammoth hands, and know my proper vent intervals ect. However, I've heard of things like "Sellick’s maneuver" being tossed around by other people, and i just have to wonder, does it really work? I'm also wondering any tips or tools of the trade anybody has for dealing with a "difficult BVM pt", other then(for those that know where i work) get your partner to intubate. I find obese patients to be particularly hard to vent properly, along with toothless patients, and heavy bearded men.
