With the EasyCal calibration service, IMT Analytics offers a simple and quick way to annually calibrate your FlowAnalyser / FlowAnalyser PRO as well as the mobile test devices CITREX H3 / CITREX H4 and CITREX H5.
Yes. The combination of an IMT Analytics test lung with the gas flow meter FlowAnalyser is a cost-effective and practical alternative to high-end test lungs. With this link it is possible to adjust not only different parameter, there is also a precise measurement of various values available.
Our Flow Analysers allow you to check and calibrate any type of medical device that generates pressure or flow. The gauges can measure bidirectional flows, pressures, temperatures, humidity and oxygen concentrations.
All gas flow meters from IMT Analytics are designed for maximum precision and reliability. However, the FlowAnalyser PF-300 has the highest accuracy, which is ± 1.75 percent. Because of its high precision, the FlowAnalyser PF-300 is considered the industry standard in some countries in Asia and Central Europe.
IMT Analytics advises users to calibrate their medical gauges once a year. This allows us to guarantee you measurements with the highest precision. With our calibration service EasyCal you can do this with little effort – worldwide. Among other things, this service includes a complete device check, the maintenance of the device and an update to the latest firmware and software.
With the following links you can directly access the operating instructions of the respective measuring device: FlowAnalyser PRO, FlowAnalyser PF-300, CITREX H5, CITREX H4, CITREX H3. In addition, you will find in our IMT Analytics academy on YouTube and our website various videos and notes with application examples and tips for the optimal use of your test device.
With the CITREX H5, you can receive updates via Wi-Fi directly on your device or download them from the IMT Analytics website. The Updates for FlowAnalyser PRO, FlowAnalyser, CITREX H5, CITREX H4, CITREX H3 can be also be downloaded to our Website. Otherwise can be software updated during the annual calibration.
The additionally available sensors – the MultiGasAnalyser OR-703 for the FlowAnalyser/FlowAnalyser PRO and the oxygen sensor for the measuring devices CITREX H3, CITREX H4 and CITREX H5 or the oxygen sensor for the FlowAnalyser – can be replaced at any time. To ensure the accuracy and reliability of the gauges, users must not replace other sensors themselves. Should this be necessary, IMT Analytics will carry out the change during the annual calibration and maintenance.
Our FlowLab software can be used across our entire range of gas flow and pressure meters – except with the CITREX H3 – while Webserver monitoring is only available for the two gas flow and pressure meters CITREX H4 and CITREX H5. FlowLab offers some additional features compared to the Webserver: This includes trending up to 100 hours, as well as the option to save and print measurements as reports. The connection to the PC takes place via USB interface.
A plateau is detected if the flow drops below a threshold value for at least 5ms and the flow is stable.
For the adult and pediatric respiratory modes, the threshold is set to 3L/min and 1L/min respectively. For the automatic respiratory mode, the threshold is automatically set based on the measured tidal volume. The flow is considered stable if it does not change quickly. This means that the flow must not change more than 0.4L/min during the plateau.
Some medical ventilators may induce oscillations when a plateau is initiated. Fast oscillations that are decaying quickly, are registered as the start of the plateau.
Furthermore, a plateau has a minimum duration of 80ms. If the detected plateau is shorter, no plateau correlated values are displayed.
Note that the plateau detection is not active for the Respiratory Mode ‘High Frequency’.
To measure the static compliance Cstat, you must ensure that your gas flow analyzer detects a plateau pressure after an insufflation (see breathing parameter Pplateau). Cstat is then calculated as follows:
Cstat = Vti / (Pplateau - PEEP)

With the FlowAnalyser PRO two new settings regarding the pressure were introduced.
The first setting is called Ventilation parameter pressure source. The second setting is called Dynamic pressure compensation. They are both available via the main menu -> settings -> measurement.
Ventilation parameter pressure source
With this setting, the reference pressure for the respiratory parameters can be selected. Three options are available: Pressure in Flow (default), Pressure Difference High and Pressure Difference Low.
As an example, by selecting Pressure Difference High and connecting the corresponding positive differential pressure port to the inside of a test lung, the peak pressure PPeak or other ventilation parameters could be determined inside the test lung. Furthermore, the gas standard and the trigger use the selected pressure as reference.
Dynamic Pressure Compensation
The pressure sensor Pchannel inside the flow channel of the FlowAnalyser PRO is located in front of the mesh. The mesh is used to generate a pressure drop from which the flow can be calculated. More about the mesh as a measuring principle can be found here https://biomedical.blog/flow-measurement-with-pneumotachograph/
When the Dynamic Pressure Compensation setting is enabled, a virtual pressure is calculated, to be found downstream in the device (hence the measurement is independent of the orientation of the device.). This replicates the behavior of the FlowAnalyser. When the Dynamic Pressure Compensation setting is disabled, the displayed pressure value is the value which is measured by the pressure sensor in the flow channel.
The Dynamic Pressure Compensation setting affects the displayed PChannel value. Since the pressure trigger threshold is set based on the displayed PChannel value, the trigger also uses the compensated value, if the setting is active. No Respiratory parameters or gas standards are affected by this setting.
The Dynamic Pressure Compensation setting for the pressure trigger threshold is only considered if the pressure source is set to Pressure in Flow. It has no effect on pressure measurement via one of the Pressure Difference sensors.

Moreover, all CITREX biomedical testing devices can distinguish the following 9 gas standards: ATP, ATPD, ATPS, AP21, STP, STPH, BTPS, BTPS-A und BTPD.
Additional gas types and gas standards are available for the biomedical testing devices CITREX H4 and CITREX H5: These are the two gas types Heliox (21% O2) and N2 as well as the 8 gas standards 0/1013, NTPD, NTPS, BTPD-A, 20/981, 15/1013, 25/991 und 20/1013.
The high number of gas standards and gas types allows a very wide range of applications in medical devices.
If you were unable to clarify your concern with the FAQs or the operating instructions of your gas flow analyser, please contact our technical support. You will receive feedback as soon as possible.
A plateau is detected if the flow drops below a threshold value for at least 5ms and the flow is stable.
For the adult and pediatric respiratory modes, the threshold is set to 3L/min and 1L/min respectively. For the automatic respiratory mode, the threshold is automatically set based on the measured tidal volume. The flow is considered stable if it does not change quickly. This means that the flow must not change more than 0.4L/min during the plateau.
Some medical ventilators may induce oscillations when a plateau is initiated. Fast oscillations that are decaying quickly, are registered as the start of the plateau.
Furthermore, a plateau has a minimum duration of 80ms. If the detected plateau is shorter, no plateau correlated values are displayed.
Note that the plateau detection is not active for the Respiratory Mode ‘High Frequency’.
To measure the static compliance Cstat, you must ensure that your gas flow analyzer detects a plateau pressure after an insufflation (see breathing parameter Pplateau). Cstat is then calculated as follows:
Cstat = Vti / (Pplateau - PEEP)

The EasyLung Neonatal is a test lung designed for neonatal ventilators. It can simulate lungs of premature babies, neonates or toddlers, which require small and precise tidal volume.
Our test lungs are used for validation and annual inspection as well as for the daily short check of ventilators and anesthesia devices. Since all of them except the EasyLung Neonatal (OD 15) have a double cone (OD 22 and OD 15), they offer ideal connection possibilities for all patient systems.
Yes. The combination of an IMT Analytics test lung with the gas flow meter FlowAnalyser is a cost-effective and practical alternative to high-end test lungs. With this link it is possible to adjust not only different parameter, there is also a precise measurement of various values available.
Good test lungs can change lung resistance and lung compliance. In addition, an adjustable leakage valve should simulate leaky hoses or leaks in respiratory masks. These features are offered by the IMT Analytics SmartLung 2000, SmartLung Adult and SmartLung Infant.
Yes. The SmartLung 2000, the SmartLung Adult and the SmartLung Infant are suitable for simulating various patient conditions. Because of the ability to change compliance and resistance, these test lungs are the optimal means for advanced inspections of your anaesthesia machines and respirators. In addition, it is possible to simulate a leak without an additional adapter.
With IMT Analytics test lungs, the functions and precision of your ventilator or anesthesia machine can be tested easily and cost-effectively before each use.
The SmartLung 2000 offers the settings to test your device according the standards IEC 60601-2-12, IEC 60601-2-13, EN 794-3. The compliance and resistance as well as a leakage can be simulated. The functionality of the patient trigger can also be tested with the SmartLung 2000.
The SmartLung 2000 is ideal for quick and cost-effective testing of ventilators and anaesthesia machines in accordance with IEC 60601-2-12, IEC 60601-2-13 and EN 794-3 standards. With a robust slider different lung compliances and resistances can be adjusted. Besides, leaks can be simulated.
With its high level of customisability, the SmartLung 2000 is also ideal for simulating patient conditions in ventilator training.
Yes. Our test lungs are an ideal tool to simulate different patient conditions and to test ventilators accordingly in different conditions. IMT Analytics’ test lungs offer an ideal complement to the CITREX H4 and CITREX H5 ventilator testers.
Our test lungs offer the unique advantage of being able to reorder all individual parts. Please contact your dealer or [email protected] directly.
SmartLungs offer the advantage over EasyLungs that volume, resistance, compliance and leakage can be set in different stages. Since they can simulate different patient conditions in this way, their field of application widens.
The SmartLung 2000 enables various compliance values to be set (simulation of lung stiffness). The smallest (at the same time also the hardest) compliance setting is 25 mL/mbar at a volume of 1000 mL.
The silicone bag of the SmartLung 2000 has a production tolerance which can lead to the bag popping out a little at the side at a volume of 1000 mL. This can lead to the compliance value deviating from 25 mL/mbar and becoming larger.
Remedy:
Use a smaller volume of approx. 500 - 600 mL to achieve a compliance of 25 mL/mbar.
