1.1 Foreword
The Ergocard CPX is a medical device manufactured by Medisoft S.A. which allows cardio-
pulmonary exercise testing (CPET) for children and adults. The Ergocard CPX is intended for
measuring gas exchange during a maximal exercise. Additionally, other options are available
to complete the cardio-pulmonary testing.
The Ergocard CPX is operated by Expair, a software program developed by Medisoft S.A. that
functions on Windows based PC systems.
The Ergocard CPX is manufactured, calibrated and applied in conformity with latest technical
requirements and official recommendations of the ATS and ERS. The Ergocard CPX adopts
Pitot tube technology for flow/volume measurement. A full weather station (temperature,
humidity and barometric sensor) for the correct determination of the BTPS correction factor
is included.
The Ergocard CPX device has two models available:
• Ergocard CPX Clinical
• Ergocard CPX Professional
The Ergocard CPX Clinical is the basic model. It uses an electrochemical cell for oxygen
measurement and a non-dispersive infrared CO
2
analyser.
The Ergocard CPX Professional model is more complete and flexible. It uses a laser
spectroscopy analyser for oxygen measurement and a non-dispersive infrared CO
2
analyser.
Options can be added to this model to complete the range of tests: lung volume
measurement, CPET under hypoxia or hyperoxia conditions, and cardiac output
measurements.
On the following pages, you will find the instructions needed to operate your instrument
effectively for practical uses. Please read this manual carefully before using the equipment
for the first time.
The content of this document is subject to periodic update and revision. Please note that
some items may be modified slightly in later versions of the software.
