Innovative instrument design meets the most powerful cardiopulmonary software in the world!

The new Q-CPX System is the culmination of several years of collaboration between Qubit Systems Inc. of Canada and Morgan Scientific Inc. of the USA.  The combination of expertise in gas measurement technology and cardiopulmonary exercise testing has led to the most innovative and comprehensive CPX system currently available.  At the heart of the system is ComPAS software, used in numerous hospitals and testing facilities throughout the USA.  ComPAS now combines comprehensive CPX and PFT measurements in an enormously powerful and versatile system for exercise testing.

Experience the Power of ComPAS Software

Simply stated, ComPAS software is the most comprehensive and sophisticated software package for CPX  and PFT measurements currently available.  No other software comes close with respect to features, data handling, reporting or ease of use.  The GUI guides the operator through all aspects of set up, calibration and running tests.  Defaults are provided for screen displays and reports, but the operator may customize any aspect of these, as required.  All raw data are always saved, but the operator has the option to select and reject data points, and to recalculate parameters at will.  For so many reasons, ComPAS software is the choice of top medical centers throughout North America.
