Bit late...
Other than the usual stuff on google scholar...

The lead author there was, last I heard, trying to get our guidelines changed so that we use paeds bags during adult cardiac arrest. I probably can't access them now, so I can't tell, but I suspect they're not exactly what you're looking for. However, I seem to remember one of them having a reasonable lit review on the topic of barotrauma. Maybe worth a look if you're stuck.
