MasterScreen™ CPX metabolic cart

Easily obtain exercise stress testing data

The MasterScreen™ CPX metabolic cart helps quickly and easily run exercise stress tests and obtain high-quality testing data. The cart can also share the data with the electronic patient record.

Stress and energy testing

The metabolic cart takes a breath-by-breath gas exchange measurement for stress testing and energy expenditure.

Optimized and controlled training

The cart can determine basal metabolic rate and exercise-dependent energy expenditure, including macronutrient breakdown.

Accurate assessments

Dynamic flow volume loops help assess a ventilatory limitation due to possible distribution or diffusion disorder.

Reduced time and risk of error

The fully automated calibration of the flow sensor and gas analyzers reduces start-up time and potential for error.

Software enhancements

The software automates calculations, and displays color-coded normal and sub-program macros for user-definable controls.

Heart rate options

The metabolic cart offers 12-lead ECG and Polar heart rate options.

Data interpretation

IntelliSupport software guides you through data interpretation using an easy-to-follow graphical flowchart.
