Ventilator Testing and Calibration: How Lung Simulators Ensure Reliable Performance

Ventilators must deliver precise volumes, controlled pressures, and consistent flow patterns—any deviation can impact patient outcomes. That’s why testing and calibration are essential for biomedical engineers, respiratory departments, and device manufacturers.

Michigan Instruments’ lung simulators replicate real pulmonary mechanics, giving teams repeatable, measurable feedback they can trust. They bridge the gap between theory and real-world performance, helping ensure ventilators operate safely and effectively.

Why Ventilator Testing Matters

Testing confirms that ventilators function as intended under patient-like conditions. It allows teams to:

  • Verify tidal volumes and pressure limits
  • Check alarms and waveform consistency
  • Identify performance drift over time
  • Validate operation after maintenance or repair

A realistic test lung simulates human lung resistance and compliance, letting technicians evaluate ventilator responses with confidence.

How Lung Simulators Deliver Realistic Feedback

Not all test lungs respond the same way. Our simulators provide:

  • Adjustable, calibrated settings to replicate a wide range of patient conditions
  • Built-in volume scales and pressure gauges for real-time feedback
  • Multiple ports for additional monitoring or instrumentation
  • Durable, repeatable performance for frequent use

This ensures each test provides actionable, reliable results.

Applications Across Settings

Hospital Biomedical Engineering: Supports routine maintenance, post-repair verification, and alarm troubleshooting with objective data.

Respiratory Therapy Education: Students see how ventilator settings translate into pressures and volumes, building confidence and understanding.

Device Development & Manufacturing: Engineers and researchers test ventilators under realistic loads, reducing variability and ensuring products meet clinical expectations.

Flexible, Practical Solutions

Michigan Instruments offers both analog and digitally enhanced simulators.

Both versions are available with or without the Spontaneous Breathing Function.  Models available are Single Adult, Adult Infant and Dual Adult

Reliable, Repeatable Performance

Ventilator calibration isn’t a one-time task. Our simulators deliver consistent results over time, with minimal maintenance, supporting repeated testing, education, and device validation.
