Well, I'm no expert yet, but I'll give this one a try.
Question: What are the whether conditions that caused the Lifelight heli not to fly? Is there water present in the ditch from rain?
I am BLS (actually still an EMT student), so I am assuming that my partner is the paramedic. I would drop an NPA because my partner's preparing to intubate and that will save him or her the trouble of taking the OPA out first. Then, I would start bagging the guy with a BVM with 15 lpm of O2 while my partner gets ready to intubate. If there is water in the ditch, I would perform an urgent move of the patient so that he doesn't drown in the water in the ditch. In fact, if there is water in the ditch, then the patient may also have water in his lungs. As soon as we get him tubed, I would transport him code 3 to the ER.
Take care!
