Infant Lung Simulators

Adult/Infant Model

“These Lung Simulators easily provide simulation of a variety of lung conditions.”

Infant & Adult Lung Simulators for Respiratory Training and Testing

Michigan Instruments Infant Lung Simulators provide realistic, repeatable simulation of infant and pediatric pulmonary mechanics for respiratory training, ventilator testing, device development, and research.

The Adult-Infant configuration combines an adult and infant lung simulator in one system, allowing users to work with different patient populations and adjust lung mechanics to create a range of respiratory conditions.

If you need to create spontaneous breathing, the model is also available as a Spontaneous Breathing Lung (SBL™).

Realistic Infant Lung Simulation You Can Adjust

Our Infant Lung Simulators are designed to help users understand how changes in compliance and airway resistance affect ventilation in smaller patients.

Adjust the simulator to create different respiratory conditions and observe how ventilators and respiratory devices respond.

Simulate:

Different levels of lung compliance
Increased or decreased airway resistance
Healthy and diseased infant lung conditions
Different ventilator settings and respiratory scenarios
Adult and infant conditions using the same system

Adult and Infant Simulation in One System

The Adult-Infant Lung Simulator combines one adult lung and one infant lung in a single unit.

The two lung models operate independently and can be used simultaneously, giving educators, engineers, and researchers the flexibility to work across patient populations.

The system provides:

Adjustable compliance and airway resistance for both lungs
Unfant tidal volume capacity up to 200 mL
Adult tidal volume capacity up to 2.0 L
Independent adult and infant operation
Realistic lung volumes and mechanical response

This configuration is especially useful for programs that train across adult and pediatric populations or need flexibility for different testing applications.

The simulator provides adjustable mechanical conditions that can be repeated across trials, helping researchers evaluate devices and techniques consistently.

Ventilator & Device Testing
Biomedical engineers, manufacturers, and service providers can use Infant Lung Simulators to evaluate ventilators and respiratory equipment under controlled, repeatable conditions.

Applications include:
- Ventilator performance testing
- Equipment verification
- Troubleshooting
- Respiratory device development
- Quality and performance testing

Respiratory Training & Education
Give students hands-on experience with infant and pediatric ventilation in a controlled environment.

Educators can adjust compliance and resistance and observe how those changes affect pressure, volume, and ventilator response.

The simulator can be used to demonstrate:
- Infant respiratory mechanics
- Mechanical ventilation
- Lung compliance
- Airway resistance
- Different disease states
- Ventilator response

HEAD SIMULATION FOR RESPIRATORY SUPPORT APPLICATIONS

An Adult or Infant Head Simulation Module can be added to support applications involving non-invasive ventilation, oxygen delivery, and other respiratory support systems.

The head module provides an additional way to simulate patient-facing equipment and introduce leak and airway-related scenarios.

Testimonials

“We have been using Michigan Instruments Training Test Lungs in our Respiratory Care program for many years and we love them. Michigan Instruments has the best test lung to easily provide simulation of a variety of lung conditions that even students can adjust to complete a large variety of lab exercises. They are versatile, and a great tool for giving our students hands-on experience with mechanical ventilation techniques, simulation of disease states for understanding pathology, performing experiments to test various concepts, and much more. They are easy to use and durable. We wish we had more!”

Dr. Ann FlintProgram Director, Respiratory Care - Jackson College

“We use the Michigan Instruments Test Lungs / Lung Simulators (TTL) in our program for demonstration of 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. In research, we use the breath simulation module to drive the left lung which lifts the right lung to act as a breathing lung for aerosol deposition studies.”

Tim Op’t Holt EdD, RRT, AE-C, FAARCProfessor and Chair, Cardiorespiratory Care - University of South Alabama

“Our Respiratory Therapy Program currently owns 4 of the Michigan Instruments TTL® Lung Simulators. We use the TTL’s to enlighten students on the basic concepts of lung compliance and airway resistance. This is especially important when training on mechanical ventilation but is also valuable with manual ventilation techniques such as use of a resuscitation bag. While our school does have a “hi-def” simulation lab, it is not always accessible, and the lab is not right here in our department. The Michigan Instruments lungs are tremendously useful tools that can be easily manipulated by our students, are cost effective, and are readily available in our own classroom. We consider the TTL’s an essential part of our training program!”

Debbie Grube RRT, MSMDirector of Respiratory Care - Muskegon Community College

“I like that they are easy for the students to use when adjusting compliance and resistance, it is also visual so they can see what is happening with those changes.”

Helen Grim, M.S., RRT, RRT-ACCSRespiratory Care Program Coordinator | Mott Community College

“Easy to use when Training students in NIV, Invasive Ventilation”
