AirwayLadder: Real-Time Plan A–D Intubation Cognitive Aid

A tablet app that guides medical teams through the official steps of a difficult airway rescue.

A step-gated tablet app that guides hospital teams through the official 2025 airway-rescue ladder during a difficult intubation, enforcing continuous oxygen delivery, first-attempt optimization, a waveform capnography confirmation gate, and timed escalation to the next rescue step.

Concept

A step-gated cognitive aid that lives on the anesthesia machine display, a wall tablet, or the videolaryngoscope cart in every OR, ED resuscitation bay, and ICU bed space. When an unanticipated difficult intubation is declared, one tap opens the DAS 2025 linear algorithm as a live ladder the whole team can see:

  • Plan A — tracheal intubation: a first-attempt optimization checklist (positioning, continuous peroxygenation, best available device, bougie ready) with a hard confirmation gate — ventilation must be verified by waveform capnography before success is declared.
  • Plan B — supraglottic airway device ventilation, Plan C — facemask ventilation, Plan D — emergency front-of-neck airway: single-tap escalation, each with its own short sub-checklist and a running elapsed-time counter that makes stop-retrying-Plan-A a visible, shared decision.

Every tap is time-stamped and exported as a structured event record for the chart and the quality system. The single wedge: convert the guideline's core philosophy — maximise the chance of first-attempt success and progress deliberately through the algorithm — from a wall poster into an interactive gate that a stressed team actually follows.

Why now

Paper [0] reports that the Difficult Airway Society built its 2025 intubation guideline through a systematic review of 1241 papers, a 3-round Delphi process, 65 meetings over 3 years, and 16 international airway experts, producing 65 recommendations organized around a linear Plan A–D algorithm. The guideline's stated priorities — continuous oxygen delivery throughout airway management, maximising the likelihood of success at the first attempt, confirmation of ventilation with waveform capnography, and progressing through the algorithm in the event of failure — are precisely the enforceable steps and gates of a step-gated app, and its explicit human-factors and multidisciplinary-teamwork recommendations are the argument for a shared visible interface over individual recall. Until this consensus codified the sequence, an algorithm app would have encoded contested logic; now the ladder, gates, and escalation triggers are defined.

AI assessment

Backed by 1 paper88

A high-utility, low-complexity cognitive aid that digitizes a gold-standard medical consensus to reduce human error during high-stress airway crises.

Evidence strength
5/5
The idea is a direct digital implementation of the DAS 2025 guidelines, which were developed through an exhaustive, multi-year, expert-consensus process involving 1,241 papers.
Market pull
4/5
Hospital systems have a strong incentive to reduce 'never events' and medical errors in intubation, making this a compelling tool for risk management and quality departments.
Novelty & moat
3/5
While digital checklists exist, the specific application of the 2025 DAS 'ladder' as a gated, time-stamped clinical record provides a distinct edge over generic checklists.
Feasibility
5/5
The product is essentially a state-machine application with a timer and a logging function, requiring no complex AI or hardware development.
Wedge clarity
5/5
The wedge is extremely sharp: a single-purpose tool for the 'unanticipated difficult intubation' event, avoiding the trap of a general anesthesia platform.
Simplicity / focus
5/5
The product is focused on one specific clinical workflow (Plan A-D) with a clear start and end point.

Who benefits

  • Difficult Airway Societyorganization

    The 2025 guideline is its product; an endorsed bedside aid is the fastest route from 65 recommendations to changed practice in member hospitals, and it already runs the education channels to distribute it.

  • Society for Airway Managementorganization

    Its members — anesthesiologists, ED and ICU clinicians — are the exact users of a Plan A–D escalation aid, and the society can distribute it through its courses and annual meeting.

  • Mayo Clinicorganization

    A multi-site anesthesia practice that needs uniform crisis behavior across dozens of ORs; a shared step-gated aid enforces the escalation decision where wall posters and individual recall fail.

  • Verathoncompany

    Its GlideScope videolaryngoscopes sit at the center of first-attempt optimization; embedding the cognitive aid on the GlideScope cart makes its device the default Plan A instrument.
