Overview
• Medical Simulation– What is it?– Why use it?
• Three Ventilator Simulators– The cheap– The expensive– The ridiculously expensive
• Designing a curriculum
What is Medical Simulation?
“A situation or environment created to allow persons to experience a representation of a real event for the purpose of practice, learning, evaluation, testing, or to gain understanding of systems or human actions.”
– Center for Medical Simulation, Cambridge, MA
What is Medical Simulation?
• Simulation vs. Simulator• Task / Skills Simulator
– Intubation, Ventilator with test lung, Bronchoscopy• Standardized Patient• Human Patient Simulator
– High fidelity simulator with a scenario– Evaluate knowledge, skills and attitude– Excellent for team training
• Virtual Reality– Virtual task– Virtual patient– Virtual scenario
Why Use Simulation?
• Patient Safety (Useful mistakes)• Experiential / Emotional Learning (next)• Teach integrative approach to problems• Standardize curriculum• Teach decision making• Practice working in teams• Planned experience of rare events• Because the ACGME and Joint
Commission wants us to…J Qual Pat Saf 2007; 31:185-202

METI-HPS and your ventilator
Pulmonary• Spontaneous respiration• Mechanical ventilation• Assisted ventilation• Chest excursion• Oxygen consumption• Uptake and elimination of anesthetic gases• Variable lung and thorax compliance• Variable airway resistance• Breath sounds• Intrapleural volume• Functional residual capacity
METI – HPS (Human Patient Simulator)
Designing a Simulation Curriculum
• Make sure you know how to do “it” correctly
• Do your Homework– Evidence Based– Expert Review
• Ask for Help– Physicians– Nurses– Respiratory therapists
Planning & Evaluating a Scenario
• What is the learning objective?– Value of the scenario is not in complexity– Use the Simulation Recipe
• Checklist evaluation– Break down into smallest identifiable task– Go / No Go for each task– Scaled evaluation sometimes more useful
• Who will evaluate?– One of the players vs. outside the room– Depends on resources available and goals of the simulation
Simulation Recipe
• Who is your target audience? – goal is to push them to the edge of their practice
• Needs Assessment – what does your audience need to work on?
• Learning Objectives - choose 2 or 3 objectives based on your needs assessment. Objectives may be clinical and/or behavioral.
Note – it is not cost effective to use simulation to teach purely factual knowledge. Use it to teach application of knowledge to a new clinical situation or to work on behaviors.
Simulation Recipe - example• Who is your target audience? – Respiratory
Therapists just out of school• Needs Assessment – Many of the therapists are very
green and get very nervous around sick patients• Learning Objectives –
– Demonstrate ability to perform patient/ventilator assessment
– Demonstrate ability to identify common problems causing tachypnea and hypoxia on the ventilator (mucous plugging, bronchospasm, pulmonary edema)
– Demonstrate the ability to respond to these problems with appropriate therapy
Simulation Recipe• Plot - Use real cases from experience or QI data
that illustrates learning objectives. Give to students verbally before the scenario and/or have it in the form of a medical record.
• Set-up - Room, mannequin, monitor, crash cart, IV poles, other props, actors as other RCP, physician, nurse, family member, etc
• Script of the scenario - What the mannequin and actors will do – start simple and focus on target audience.
Simulation Recipe-example• Plot –
– RT called stat to patient’s bedside – 62-year-old man with pneumonia on ventilator– Peak pressure is alarming on ventilator and patient is hypoxic
due to mucous plugging• Set-up –
– SimMan - RR- 34, BP-190/100, P-114, O2 sat-85% , decreased breath sounds
– Ventilator set with AC, rate-16, TV-420cc, peak pressure limit of 40, FiO2-50%, vent is alarming with Peak pressure limit
– ASL 5000 simulator – 85% of max tracheal resistance– Assigned bedside nurse actor (can direct simulator issues)
• Script of the scenario – – Patient will continue to deteriorate until patient is removed
from ventilator, bag mask ventilated and suctioned– If above done, resistance will fall to normal and ventilation will
be normal when ventilator restarted with improved patient VS
Simulation Recipe
• Medical record (Optional) – patient notes, history and physical, medication list, ECG’s, labs, x-rays
• Teaching Points – Critical actions -- series of steps necessary to
successfully complete task and demonstrate understanding of the teaching points.
– Common Pitfalls -- common mistakes that your learners may make that you specifically want to remind them to avoid.
• Debriefing – most important part– based on the teaching points outlined above – based on what you observed during the simulation

Summary – Simulation Recipe
• Simulation allows students to experience a “true- to-life” scenario where they can make mistakes and learn without hurting patients
• Know your audience and their needs• Develop learning objectives (2-3)• Develop the plot, set-up and script• Observe critical actions/common pitfalls• Give Feedback/Debrief• Have serious fun and your students will, too!
