The Cortex MetaMax 3B-R2 – The Ultimate CPET Device

The Cortex MetaMax® 3B is a battery powered CardioPulmonary Exercise Testing (CPET) system for professional outdoor use. Designed to meet your individual needs – no matter how exceptional they might be. The Cortex MetaMax 3B-R2 uses Breath-by-Breath measurement method.

Never lose any data

During a CPET test, the device continuously measures Oxygen concentration, Carbon Dioxide concentration and Volume flow. The values recorded are stored in the device’s internal data logger, sent in real time by Bluetooth to the PC and evaluated in using the software MetaSoft Studio. This allows for use in offline mode and gives you peace of mind that your data will never be lost.

Long Range Bluetooth for increased range

The Cortex MetaMax 3B-R2 has new Long Range, Bluetooth technology allowing for much more stable data transmission with maximum ranges of more than 1,000 m. Even in densely populated regions with high exposure to electromagnetic fields, the new technology strongly increases the robustness against such disturbing factors.

Therefore reliable transmission of all test data between MetaMax 3B-R2 and the Metasoft Studio software is ensured over considerably longer distances.

Flow sensor options

Cortex present two options when it comes to measuring Ventilation, choose from either; Triple ‘V’ Reusable Turbine or a Disposable Turbine. At point of purchase you must choose which option you would prefer, at a later date you can choose the alternative flow sensor if required.

MetaSoft Studio

The beating heart of all Cortex systems is the software, MetaSoft Studio. It manages and monitors all processes of Cardiopulmonary Exercise Testing and controls all peripheral systems such as; Heart Rate, Blood Pressure and Ergometers, amongst other measurement systems.

Intuitive Workflows

MetaSoft Studio allows users to easily perform an exercise test in a simple, step by step way through guided workflows. These simple, repeatable steps make learning how to use MetaSoft Studio easy. Allowing you more time to spend testing and less time on staff training.

Customisable Graphical display

Useful graphical displays make it easy to evaluate the measurement data. The user can select from different display options or configure the display of test data according to his or her preferences.Reporting functions allow you to display the test results in a clearly structured form.

Further expand MetaSoft Studio to suit your needs


All Cortex products for CPET can be used as spirometers. The software features basic Spirometry functionality as part of MetaSoft Studio. Allowing you to perform a Maximum Flow Volume loop prior to testing.

The MetaSoft Studio Spirometry module allows for further spirometry evaluation of a test subject. It is possible to perform spirometry tests at rest such as VC, FVC and MVV tests independently. The validation criteria of the individual manoeuvres are compliant with the ATS criteria and the available standard values for spirometry naturally include ‘LLN – Lower Limit of Normal and ‘Z-Score’.

Energy Metabolism for CPET

A well-functioning energy metabolism is the prerequisite for any type of performance. A person’s metabolism can easily be improved by well-balanced training units. This license provides you with all values of energy expenditure and indirect calorimetry during a CPET-Test. The variables fat, carbohydrates and proteins are available for live display during exercise and the according analysis.

Basal and Resting Metabolic Rate

With this license you can measure either basal or resting metabolic rate. A specially created module provides appropriate standard values, as well as other settings such as different calculations methods for BMR/RMR or steady state conditions. A pie chart of substrate utilization and live steady state bars during
test allow easy individual analysis.

Performance Assessment

This option gives you an inter- and intra individual assessment of your client’s performance. Both comparisons (one to reference values and the other to the own performance) will be provided in easy to understand reports.

Furthermore, you will obtain very precise and individual heart rate training zones for your client. Ten (10) predefined modules plus free configurable training zones based on both ventilation threshold VT1 and VT2 may be created.

Exercise Scheduler

The Exercise Scheduler is built up on the “PA and Heart rate full training zones.” There are extensive tools at your disposal to create individual endurance-oriented micro-cycle, meso-cycle and macrocycle
training plans. Numerous exercise schedule templates are included in the package. Moreover, you can freely create and edit your own templates.

Note: The license ‘MSS Performance Assessment’ is mandatory to acquire the ‘MSS Exercise Scheduler’.

6 Minute Walk Test

This license allows the 6-minute-walk-test (6MWT) within MetaSoft Studio. The 6MWT can be performed as a stand-alone or complex test in combination with a CPET test. Corresponding standard values are stored. In addition, each round and minute values can be compared to norm values or the oxygen uptake to the VO2max can be considered in the analysis.

Pre-operative Risk Assessment

The Pre-operative risk assessment module has a semi-automatic results interpretation features, especially designed in collaboration with Paul Older to evaluate risk relating to surgery. A 4-step-interpretation will help to objectively understand the surgical risk and is a tool for hospitals to derive an appropriate perioperative management plan with help of CPET results.

Hardware options for the Cortex MetaMax 3B-R2

Calibration Kit

Every Cortex device requires periodic calibration to ensure consistency or measurement. Our calibration kit includes two small bottles of calibration gas, an “on-demand” regulator, barometer and carry bag as a minimum. Should you be using the re-usable Triple V Turbine, the calibration kit will also include a 3L Volume Syringe. Otherwise, this is not required as the disposable turbines are pre-calibrated and disposed of after use. Available here

Stationary Kit

Do you want the best of both worlds when it comes to CPET testing? The Cortex MetaMax 3B-R2 Stationary Kit effectively turns your mobile device into a lab based CPET system. Supplied with a longer (2m) sample line, Opto-electronics extension cable (flow sensor) and external power supply, the Cortex MetaMax 3B-R2 no longer needs to be worn on the person to perform a measurement.

CORTEX Remote Control

The new touch-screen Remote Control from CORTEX allows you to see MetaMax 3B-R2’s essential measuring data such as heart rate, oxygen uptake, carbon dioxide output, respiratory exchange ratio, breathing rate, tidal volume, minute volume, velocity and load during a field test on a handheld device.

This way, you constantly receive valuable feedback from MetaMax 3B-R2 without having to take along a PC or laptop. You also have the option to use the Remote Control to carry out all calibrations required in the field test.

GPS receiver

The optional GPS receiver allows for speed of an athlete to be determined during field testing. Additionally, an altitude profile of a covered distance relative to the starting point can now be measured.

Blood Pressure – Metronik BL-6

The METRONIK BL-6 is a robust, easy to use blood pressure device with very high reliability. It is designed for the measurement of non-invasive blood pressure in most applications. Use of the Metronik BL-6 is only possible when combined with the Stationary Kit.

The Metronik BL-6 features the most advanced Blood Pressure Cuff you can buy thanks to each cuff having a removable bladder with in-built microphone, thus allowing for the cuff to be washed between uses. Learn more about the Metronik BL-6 here.

Service & Warranty

Worldwide, the “Made in Germany“ label stands for quality and a promise of guarantee. CORTEX feel committed to these values and keep this promise every day. All Cortex products are manufactured with precision to ensure reliability in all applications.

The Cortex MetaMax 3B-R2 is considered almost maintenance free from a day to day perspective, with a gas calibration only mandated once every 4 weeks. However, whilst the device has been manufactured to high standards it is recommended that an annual service is carried out. The Cranlea service team has many years experience working with Cortex devices and can validate your system on-site. Contact our service team here.
