Low Medical Gas Pressure — Diagnostic Mini-Scenario
Project Overview
Designing a guided diagnostic mini-scenario to help healthcare facilities technicians troubleshoot low medical gas pressure indications in patient care environments.
The activity focuses on reinforcing systematic inspection and troubleshooting practices aligned with NFPA 99, using short, decision-based tasks rather than full simulations.
Designing the Mini Scenario
This experience is structured as a set of three independent diagnostic tasks that learners can complete in any order. Each task presents a realistic system issue related to medical gas pressure indicators and requires the learner to apply inspection logic before taking action.
The design prioritizes diagnostic reasoning over speed, allowing learners to pause, reflect, and retry with guidance.
Client Context
Facilities technicians often encounter intermittent or ambiguous medical gas pressure indications that do not immediately point to component failure. In practice, these situations require careful inspection, standard-based judgment, and avoidance of unsafe shortcuts.
The client needed a lightweight practice activity that reinforced correct troubleshooting sequences without overwhelming learners or interrupting operational training schedules.
What this activity is (and isn’t)
It is a guided diagnostic practice, not an exam or simulation.
It reinforces standard inspection logic through short decision tasks.
It supports skill development with hints and corrective feedback.
- It is not a scored assessment or audio-driven experience.
Design Approach
Each task is designed with two attempts. On an initial incorrect response, learners receive a contextual hint aligned to NFPA guidance. On the second attempt, full feedback is provided before progression.
The activity includes multiple interaction types—MCQs, drag-and-drop ranking, and click-to-reveal—to reflect the varied nature of real troubleshooting work while maintaining a consistent instructional flow.
Key Components
Three independent diagnostic tasks with free task order
Two-attempt structure with hints and corrective feedback
NFPA 99–aligned inspection and decision logic
Mixed interaction types to support applied reasoning
Safety-first framing with explicit “do not bypass” guidance
Reflection-oriented key takeaways at completion
Role & Contribution
I designed the instructional flow, task mechanics, feedback logic, and developer guidance.
This included translating regulatory standards into concise diagnostic decisions, defining hint and feedback rules, and shaping the activity to function as a quick, repeatable practice experience.
Outcome
The mini-scenario helps learners strengthen diagnostic habits without relying on trial-and-error or unsafe assumptions.
It supports more consistent troubleshooting behavior, reinforces inspection-first thinking, and builds confidence in applying medical gas standards in real facility contexts.
Reflection
This work demonstrates how short, well-scaffolded scenarios can be used to reinforce professional judgment in safety-critical environments.
By focusing on how technicians think, rather than simply what they know, the activity supports safer decision-making and more reliable system maintenance.
