The problem that shaped the device
Tubes are built forgas exchange.Bougies are built fortracheal access.
Endotracheal tubes are built to ventilate. Tube introducers are built to travel. Their adoption—and the evolution of the devices and techniques around them—reflects a single clinical reality: sometimes the most reliable way to deliver the tube is to secure access to the trachea first.
This PACscape traces the evolution from the classic gum-elastic bougie to modern tube introducers designed for the era of video laryngoscopy. It examines the techniques and evolving evidence supporting their use—not only as backup rescue devices, but as frontline tools within a deliberate, repeatable strategy for first-pass success. Explore the collection online, or scan the same visual artifacts as you move through a physical practice space.
Read the evolution
Connect design changes to the clinical problems each generation attempted to solve.
Select deliberately
Distinguish devices by geometry, stiffness, tip control, and the route they make possible.
Build the hand skill
At the station, practice classic, preloaded, and next-generation tube-delivery sequences while developing the microskills that make each technique reliable.

Build the physical collection.
Print the eight posters, place the corresponding devices at each station, and turn the collection into a hands-on comparative study. The learner should be able to see the design, handle the object, and rehearse the technique in one continuous encounter.
