There is new textbook called Practical emergency resuscitation and critical care, with notable editors like Scott Weingart no less!
Our good friend Seth Trueger of MDaware wrote the airway chapter (so it must be good)
Here is a free sampler of the airway chapter
Declaration: Seth and I make no money from the textbook. We do not receive any royalties from its sale.
This article was peer reviewed by Dr Seth Trueger and myself.
