ERS technical standard – Reference values for cardiopulmonary exercise testing: summary report and a call for action

Significant heterogeneity in CPET testing methodology and outcomes between sites precluded the development of reference ranges for VO_2peak and W_peak. This Task Force has developed a framework for prospective data collection with strictly standardised protocols and centralised data analysis to reduce variability and establish robust, clinically meaningful reference ranges for CPET outcomes.
