Clinical Usefulness of Response Profiles to Rapidly Incremental Cardiopulmonary Exercise Testing
Figure 1
Noninvasive estimation of the lactate threshold by the -slope method (gas exchange threshold (GET), panel (a)) and the ventilatory method (ventilatory threshold (VT), panel (b)) in a normal subject. Note that the GET slightly precedes the VT as the later depends on the ventilatory response to the “extra-” generated by buffering of associated with (lactate) increase. and refer to the two sequential slopes (before and after the GET) with being characteristically steeper than (i.e., slope inclination >1.)
