Lung Simulators for Training, Testing, and Research

“Michigan Instruments has the best test lung. They are easy to use and durable. We wish we had more!”

Ann Flint, Grand Valley University

Realistic respiratory simulation you can see, feel, and measure.

Training under pressure? Verifying device performance? Developing and testing new respiratory technology? Each of these moments depend on simulation tools that behave like real lungs, not simplified models.

At Michigan Instruments, our TTL®, PneuView® and Spontaneous Breathing Lung Simulators are designed to replicate true pulmonary mechanics. They respond dynamically to ventilation, provide realistic lung volumes, and deliver repeatable performance you can trust across training, testing, and research environments.

“The Michigan Instruments lungs are tremendously useful tools that can be easily manipulated by our students, are cost effective and readily available in our classroom. We consider the TTL’s an essential part of our training program.”

Built for How You Actually Use Them

Classroom & Clinical Training
Hands-on learning works best when students can see cause and effect in real time.

Our lung simulators help create those “aha” moments by allowing learners to adjust compliance and resistance, observe realistic ventilator responses, and build confidence through repetition. No unnecessary complexity. Just clear, clinically accurate feedback that reinforces understanding.

Ideal for:
- Respiratory therapy programs
- Hospital education departments
- EMS and prehospital training
- Ventilator management instruction

Biomedical Engineering & Device Testing
When you’re calibrating, verifying, or troubleshooting respiratory equipment, consistency matters.
Michigan Instruments lung simulators provide stable, repeatable mechanical behavior across repeated tests. That reliability supports confident evaluation of ventilators, anesthesia machines, CPAP/BiPAP systems, circuits, valves, and accessories without introducing unwanted variability.

Common applications include:
- Equipment verification and validation
- Preventive maintenance and calibration
- Performance benchmarking
- Troubleshooting under controlled conditions

Research & Development
For engineers and researchers, data integrity starts with predictable simulation.
Our simulators are fully to scale and offer a wide range of calibrated compliance and resistance settings. That flexibility allows you to recreate hundreds of healthy and diseased lung conditions while maintaining consistent mechanical behavior across trials.

Used in:
- Ventilator and respiratory device development
- Quality assurance testing
- Pulmonary physiology research
- Specialized breathing system evaluation including SCBA, aviation, diving, and aerosol delivery

“We use the Michigan Instruments Test Lungs/Lung Simulators (TTL) in our program for demonstration for mechanical ventilation, laboratory practice with ventilators, and aerosol and ventilator research. The TTL is valuable in showing students the effects of changes in compliance and resistance on volume and pressure. They are also valuable to show differences between tracheal and intrapulmonary pressure.”

Why Michigan Instruments Lung Simulators Feel Different

Because they behave differently.

Unlike simplified test lungs, our simulators include realistic residual lung volumes and lifelike responsiveness to therapy.

When ventilated, they move and react like real lungs, helping users trust what they’re seeing and measuring.

Each device is fully calibrated and includes a Certificate of Calibration. We recommend recalibration every two years.

Lung Simulator FAQs

Click on the question below to see the answer. If you have a specific question, please contact us directly.

How do I choose the right lung simulator?

The right lung simulator depends on how you plan to use it. First, choose your configuration: Single Adult, Dual Adult or the Adult-Infant for the widest range available. Next decide if you want a TTL or PneuView version. They both provide the same fully adjustable and realistic mechanical representation of the human pulmonary system. The TTL provides analog readings while the PneuView systems add electronic measurement and data visualization for testing and analysis. Finally, if you want spontaneous breathing capability, be sure to include the Spontaneous Breathing Lung (SBL) module (an available addition to all TTL and PneuView devices).
Can’t Decide? Contact us, we would be happy to talk it through with you.

Why does realistic lung behavior matter in training and testing?

Realistic lung behavior helps users see and feel how ventilators interact with actual pulmonary mechanics. Simulators that respond dynamically to changes in compliance and resistance reinforce correct decision-making, improve skill transfer to clinical settings, and support accurate device evaluation. Without realistic behavior, training and testing results can be misleading.

Can one lung simulator support multiple use cases?

Yes. Michigan Instruments lung simulators are designed to support training, testing, and research using a single platform. Adjustable compliance and airway resistance settings allow users to simulate a wide range of lung conditions, making the same device suitable for classrooms, hospital labs, biomedical engineering work, and device development.

What makes Michigan Instruments’ lung simulators different from other test lungs?

Michigan Instruments lung simulators are fully to scale, include realistic residual lung volumes, and provide a wider range of calibrated compliance and resistance settings than many basic test lungs. They move and respond like real lungs when ventilated, which improves training realism and measurement confidence across repeated use.
