I gota ad my 2 cents. I think it's a great idea for EMT's to use combitubes. it helps secure an airway, you get less gastric distention (come on, I know you have all seen the rookie bag the pt at a rate of 40X a min and with as much force to cause a double pneumo) and it's one less thing an als provider has to be concerned with during an intercept. You can't push drugs down (unless you are a mirical worker and get it in the trachea) but that's what IV's are for. if you got no IV access, then remove and try for an ETT, but I would love to see a combitube inplace prior to my arrival (on a cardiac arrest or resp arrest pt). as for ECG monitoring and interp strips, I'm leaning towards no. There is so much info you have to take into concideration when reading a strip and so many diffrent effects meds do, that I feel if you want to hook up the monitor, then become an als provider. Plus that desire to just see what rhythm the pt is in even when not an als call might become too great and that's not something an EMT -b should be doing. If you want to learn to better yourself, that's great and I'm all for that, but not for interpreting rhythms in the field as a non als provider.
