Measuring size of OPA and NPA mnemonic

The oropharyngeal and nasopharyngeal airway are temporary airway devices. You need to select an appropriate size before inserting the airway.

Here is a mnemonic for the same!

Size of Oropharyngeal airway mnemonic: AA
Angle of mouth to angle of the mandible

Size of Nasopharyngeal airway mnemonic: TT
Tip of the nose to the tragus

If you get confused between which one is for which - AoA and TnT mnemonic.

That's all!
