Did you know that one or more of our test lung simulation products are used in the majority of Respiratory Therapy programs throughout the United States and even in many countries around the world? It’s true! Test lung simulators designed and manufactured by Michigan Instruments are utilized in many Colleges, Universities and Training Schools because of their accurate and reliable human pulmonary system simulation capabilities.

As we continue to improve our line of test lung simulators, the investments made by Respiratory Therapy programs have never been so good – and here 10 reasons why.

Test lung simulators work well within Respiratory Therapy programs because:

  1. Facilitators can simulate a wide variety of healthy and diseased lung conditions by altering the lung compliance and airway resistance in a one- or two-lung simulation.
  2. Students work with a realistic total lung volume and residual volume (especially when using the Dual Adult Lung Training & Test Lung).
  3. There is great versatility in the models in regard to introducing gases, tapping into the lungs or airways, and connecting axillary devices like CO2 monitors.
  4. With the Dual Adult Training & Test lung, facilitators can simulate unilateral lung disease and the resulting ventilation dynamics.
  5. You can simulate a spontaneous breathing patient and evaluate the response of devices in various support modes.
  6. The available Head Simulation Modules facilitate education and studies with various oxygen delivery systems and non-invasive ventilation devices/techniques.

With the addition of PneuView Software

  1. You can get data and waveform displays of pressure, volume, and flow, even when using simple ventilation devices like BVM’s, emergency ventilators, and CPAP systems.
  2. Facilitators can store recordings of ventilation runs for later demonstration and evaluations.
  3. Students and others can conduct research and easily save their data.

At Michigan Instruments, our Test Lung Simulators are used for a number of different applications. From classroom instruction to product evaluation, pulmonary research or clinical intervention, our customers value the versatility, accuracy, and realism of our test lung simulations. But what if the simulation and testing isn’t for a human?

The Challenge:

A veterinary facility located in Ponte Verde, Florida recently reached out to the experts at Michigan Instruments with a unique request.

They were developing a ventilator designed for use on dolphins when putting them under anesthesia and needed a way to test this piece of equipment. The Test Lung Simulator had to be able to measure at a much larger pulmonary capacity than is necessary for humans – 12 liters to be exact – and there was nothing available on the market.

In short, they needed to simulate dolphins under anesthesia, and needed a device that could simulate and measure large tidal volumes to successfully test their equipment before using it on live animals. They looked to Michigan Instruments for help.

The Solution:

The team at Michigan Instruments began developing and testing a unique solution for the veterinary clinic, helping them ensure their ventilators were safe and effective for medical use.

By taking three of our dual adult test lungs and manufacturing a special airway assembly that connected all three together, we were able to provide the lung capacity that was required to simulate the dolphin pulmonary system.

We forged and built the custom airway in-house, developed in-depth operational documents and sent the test lungs directly to the veterinary clinic with everything they needed to accurately test their equipment.

The Results:

The veterinary clinic was able to successfully test their ventilators in preparation for use on large mammals such as dolphins. They were also able to train other specialists on their ventilator’s operation in advance of any anesthetic surgery.

From Michigan Instruments’ perspective, it was a lot fun to develop this custom product for such a unique application!

“It was a fun adventure,” says Eric Hadesh, Document Control Manager at Michigan Instruments, “it was definitely something we don’t do day-to-day and it was interesting to determine how best to complete and assemble the system, then come up with the pictures and documentation. It was a great learning experience for us, but also an exceptional application of our lung simulation products and capabilities.”

This is just one example of many that shows how Michigan Instruments continues to forge ahead as an innovative pioneer in the respiratory care industry. Setting the standard in quality, versatility and durability, we never shy away from a challenge and are always operating from a ‘what’s next’ mentality.

Train & Practice with Mechanical Ventilators

Our Training Test Lungs are mechanical devices that simulate the dynamic anatomic forces at play during ventilation. These sophisticated devices provide students with the ability to train and practice with mechanical ventilators and other respiratory care equipment before and during their clinical experience. The realistic simulations and real-time feedback help students learn how to properly manage a variety of respiratory conditions, better preparing them for real lifesaving scenarios.

Unlike more basic test lungs, Training Test Lungs 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 as well.

The study referenced here and available for download (PDF) here used the Michigan Instruments Dual Adult TTL to test several emergency and transport ventilators over their range of operation.

The TTL was able to simulate various respiratory conditions with decreased or increased compliance and resistance. The TTL was also used to simulate spontaneous breathing patients, using one lung as the “driver” and one as the spontaneous breather. This allowed the investigators to evaluate the responsiveness of the ventilators to patient effort. In Summary: applying realistic loads and forces on these ventilators revealed important differences, including significant weaknesses in the performance of some models.

Evaluation of Ventilators Used During Transport of Critically Ill Patients: A Bench Study

by Salah Boussen PhD MD, Marc Gainnier PhD MD, and Pierre Michelet PhD MD

OBJECTIVE: To evaluate the most recent transport ventilators’ operational performance regarding volume delivery in controlled mode, trigger function, and the quality of pressurization in pressure support mode.

METHODS: Eight recent transport ventilators were included in a bench study in order to evaluate their accuracy to deliver a set tidal volume under normal resistance and compliance conditions, ARDS conditions, and obstructive conditions. The performance of the triggering system was assessed by the measure of the decrease in pressure and the time delay required to open the inspiratory valve. The quality of pressurization was obtained by computing the integral of the pressure-time curve for the first 300 ms and 500 ms after the onset of inspiration.

RESULTS: For the targeted tidal volumes of 300, 500, and 800 mL the errors ranged from –3% to 48%, –7% to 18%, and –5% to 25% in the normal conditions, – 4% to 27%, –2% to 35%, and –3% to 35% in the ARDS conditions, and 4% to 53%, 6% to 30%, and 30% to 28% in the obstructive conditions. In pressure support mode the pressure drop range was 0.4 –1.7 cm H2O, the trigger delay range was 68 –198 ms, and the pressurization performance (percent of ideal pressurization, as measured by pressure-time product at 300 ms and 500 ms) ranges were –9% to 44% at 300 ms and 6%– 66% at 500 ms (P < .01).

CONCLUSIONS: There were important differences in the performance of the tested ventilators. The most recent turbine ventilators outperformed the pneumatic ventilators. The best performers among the turbine ventilators proved comparable to modern ICU ventilators. Key words: mechanical ventilation; transport ventilator; bench study; ICU patient transport; pressure support ventilation; inspiratory trigger; ventilator performances.
