KY jelly (lube for the airways)
I'm not sure where you're planning on inserting your airways where you'll be needing KY Jelly <img src="/images/graemlins/wink.gif" alt="" /> I've used Lidocaine gel for ET tubes. Nothing for the hard plastic orals (mostly used to protect an ET tube).
IV stuff... oxygen bottle ... sterile saline
Are you a physician? I believe all this requires an Rx. At least it did back when I was a paramedic. You also have shelf life issues. How do you roll over your IV stock with fresh supplies?
I agree with what others have said about the Magills. Used them once in a decade in the back of an ambulance. In desperation, after a drunken patient had tried to swallow a side of beef ... whole. Didn't work. The swallowing OR the Magills! <img src="/images/graemlins/wink.gif" alt="" />
If you personally own one of these, why are you asking first aid advice on this forum? No offense intended, but there are probably only a few of us here who even know what this is and are trained in its use. Either you have significant medical training to use (and own) all this stuff, or you've collected things that you really shouldn't be messing around with without training and experience. Again, no offense intended, but you questions seem odd taken in context with the advanced equipment you apparently own. Please don't tell me you've got a LifePak sitting on your coffee table! <img src="/images/graemlins/wink.gif" alt="" />
