Clinical Usefulness of Response Profiles to Rapidly Incremental Cardiopulmonary Exercise Testing
Figure 2
Procedures to establish 3 dynamic submaximal relationships by simple linear regression during incremental CPET in young (24-yr-old, left panels) and old (70-yr-old, right panels) subjects. (a) oxygen uptake work rate (WR); (b) heart rate (c) minute ventilation carbon dioxide output . The arrows show the range of values considered for analysis. RCP is the respiratory compensation point.
