Patient condition simulation

Test lungs which are used for more than just a routine functional check require an adjustable compliance and resistance. Only by assessing these values, can changes in a patient’s condition be simulated and understood.

A good test lung allows for changing the resistance from 5 mbar/L/s up to 200 mbar/l/s. The compliance (stretchability) must be adjustable between 1 mL/mbar and 30 mL/mbar. Furthermore the test lung should have an adjustable leakage in order to simulate leaky tubes, masks and mishandled connections.

The easy adjustment of compliance and resistance make the IMT Analytics test lungs a compact and user-friendly tool for your daily needs.

IMT Analytics test lungs are a low cost alternative to high-end test lungs, who not only allow for adjustable parameters but also record measurements. If you combine an IMT Analytics test lung with our FlowAnalyser, you will achieve a comparable performance.

The benefits of IMT Analytics test lungs

  • Every part is exchangeable
  • Autoclavable
  • High quality
  • Longevity
  • Patented

Adjustable resistance

Simulate multiple airway-resistances with a simple twist of the connector.

Leakage simulation

The leakage can be adjusted by turning the bolt on the side.

Adjustable compliance

Change the lung-stiffness by simply shifting the slider without the need for an adapter.

Compact and user-friendly

Always ready to hand with the practical transport bag.

SmartLung 2000

With the new SmartLung 2000 you can test if a ventilator is in compliance with the following standards: IEC 60601-2-12,IEC 60601-2-13 and EN 794-3

  • 2000-ml-bag
  • Applicable volume from 0 to 1000 mL
  • Testing according to IEC standards (ventilators and anaesthesia machines)
  • The only test lung on the market that covers all the necessary test points
  • Outstanding features for patient simulations in ventilator training

With the SmartLung adult, you can control the function of a ventilator over all norms. The SmartLung 2000 has the same size as ordinary test lungs, but it comes with an adjustable compliance and an adjustable resistance from 5 up to 200 mbar/L/s. The leak-compensation of a ventilator can be tested, thanks to the controllable leakage. It is also possible to test the patient-trigger-function with the SmartLung 2000.

The SmartLung 2000 is the best tool for testing your ventilator and anesthesia devices and an ideal addition to the flow- and pressure measurement device FlowAnalyser. By simply using the slider, the test lung can simulate different degrees of lung-hardness according to different standards and a simple twist of the connector is all it takes to simulate different airway-resistances.

SmartLung Adult

The SmartLung Adult simulates adult lungs.

  • 1000-mL-bag
  • Applicable volume from 0 to 600 mL
  • The lung parameters resistance, compliance and leakage can be set to different levels
  • Extremely handy and user friendly
  • Top price-performance ratio

SmartLung offers the same performance as large, expensive test lungs. It is extremely simple to use and so compact that it can be connected directly to the ventilator tubing system. The SmartLung is unbeatable in terms of price/performance ratio. Resistance (airway resistance), lung compliance and leakage are all adjustable.

Its size eliminates the cumbersome side-tables needed by large test lungs. Different bag sizes ensure that virtually all patient lungs can be simulated; from babies to adults. The SmartLung does not require any additional adapters.

The Leakage is infinitely variable and enables verification of premature infant ventilators as well as mask ventilation. Even the sensitive function of the patient flow triggering can be tested with the SmartLung.

Combined with the FlowAnalyser from IMT Analytics you can also measure pressure, flow and volume specifications with the SmartLung.

  • 500-mL bag
  • Applicable volume from 0 to 200 mL
  • The lung parameters resistance, compliance and leakage can be set to different levels
  • Extremely handy and user friendly
  • Top price-performance ratio

IMT Analytics test lungs are a simple and cost-efficient solution to safely verify ventilators and anesthetic devices for functionality and precision.
