I've noticed that a lot of people are starting to carry advanced first aid kits when at the range or out and about, one of the devices that a lot of these kits has are nasal airways, Here is a video that was put together to help out basic EMS crews in the use of two different types of airways, the latter is the NPA that is in these kits.
