Normal values for cardiopulmonary exercise testing in children

BACKGROUND: A reference set of data of normal values of newly developed cardiopulmonary parameters of exercise testing in an 8-18-year-old population is lacking. PATIENTS AND METHODS: Cardiopulmonary exercise testing was performed in 175 healthy school children (8-18 years old). Continuous electrocardiography was performed, and minute ventilation, oxygen uptake (VO2), and carbon dioxide (CO2) production were measured continuously with a respiratory gas analysis system. RESULTS: Peak VO2/kg did not change with age, whereas the ventilation to carbon dioxide exhalation slope was lower in the olde... Mehr ...
