Mnemonics should only be used when you can't remember what you need to do or ask. Unfortunately many emt classes hammer the mnemonics into the students' heads.I found the mnemonics helped when I was in paramedic school. However, now before I intubate someone, I'm looking for the clues that may predict a difficult intubation without having to rely on reciting LEMONS or BONES. The same with a history. New EMTs always try to gather a SAMPLE, while experienced providers have a focused Q and A to get the information they need.
