Improved simulation system for routine cardiopulmonary exercise test equipment. Part II: A new metabolic simulator system: practical applicability. The European Coal and Steel Community (ECSC) Working Group on Standardization of Stress-test Methods.
The utilization in clinical practice of an improved metabolic calibrator was tested. The morphological characteristics and integration patterns of the signals were checked with a reference stress-test instrument and compared with physiological recordings. No significant differences were observed. Conversion formulae were developed to compare the calibrator's data with those produced by routine instruments. Simultaneous graphical representations of erroneous and reference signals and computer processing of data allowed on-line detection of even minimal sources of error in dynamic working conditions.
