Lung Simulation

Why TTL & PneuView?

With a range of calibrated lung compliance and airway resistance settings, our test lungs can simulate a wide variety of healthy and diseased pulmonary conditions, and provide accurate measurements of key respiratory parameters. Unlike more basic test lungs, TTL and PneuView systems offer residual lung volumes and a dynamic response to therapy that more realistically represents the human pulmonary system. Our systems are available in Adult and Infant models.

TTL vs PneuView – What’s Right For You?


TTL Training Test Lungs

(no Electronics or Software)

The Michigan Instruments TTL Test Lungs are mechanical (analog only) simulators that replicate a wide variety of pulmonary conditions and pathologies. They provide accurate measurement of lung volumes, lung pressures, and airway pressures using analog gauges and printed scales. TTL’s provide a dynamic simulation and response to mechanical ventilation and other therapies, making them ideal tools for teaching, testing, training, and research. TTL’s are available in adult and infant configurations.

PneuView Systems

(TTL with Electronics and Software)

PneuView Systems add electronics and software to the TTL Test Lung package. The PneuView electronic module is built into the Test Lung assembly and incorporates pressure transducers, environmental sensors, signal conditioning and analog-to-digital converter circuitry. This module communicates with PneuView software installed on a host computer. The PneuView software can display several respiratory parameter measurements and waveforms in real time. This data can be graphed, tabulated, or digitally recorded, then retrieved for later review and analysis.
