Orientation // PACscape preview
Great views are only
the beginning.
Meet the system, watch the opening film, and preview the four chapters that will turn a powerful view into a deliberate intubation strategy.
Entered from the physical poster? You are in the right place. The online and in-person paths begin with the same short film.
One idea before you begin
See the system. Then learn the moves.
HAVL carries the camera around the tongue rather than requiring a direct line of sight. That changes both the view and the route the tube must travel.
Across the next four posters, you will build the mental model, control the blade, deliver the tube with a rigid stylet, and combine those skills into one deliberate sequence.
The screen is a map, not the destination.
The largest image is not always the best working view.
Tube delivery is a related—but separate—skill.
Your route through the PACscape
Four posters take it from here.
Each poster adds one layer. Move in sequence online, or enter at the matching station when you are learning in the physical space.

A signal—not a universal promise
Why the strategy matters.
In a single-center trial of 8,429 cardiac, thoracic, and vascular surgical procedures, repeat attempts were less frequent with hyperangulated video laryngoscopy than with direct laryngoscopy.
The setting matters. This supports HAVL in that operating-room context; it does not establish a universal default for every airway.

Two ways to go deeper.
These short extensions add evidence context and strategic perspective without interrupting the main route.
Skip this extension ↓01What the evidence tells us＋
Two single-center operating-room trials support stronger HAVL performance in defined populations: fewer repeat attempts than direct laryngoscopy in cardiac, thoracic, and vascular procedures, and higher first-attempt success than Macintosh videolaryngoscopy in anticipated difficult ENT or maxillofacial airways managed by experienced consultants.
These findings support the strategy in those settings. They do not promise effortless intubation or establish one universal device choice for every airway.
02Where HAVL belongs in an airway strategy＋
HAVL can be valuable when creating a direct line of sight is difficult or undesirable, but it remains one part of a complete airway plan. Match the technique to the patient, setting, available rescue options, and the expertise of the team.
Device fluency matters—and so does recognizing when the geometry, conditions, or clinical trajectory should prompt a change in strategy.
