1. Etiological Clues From Cardiopulonary Exercise Testing
Measurements obtained during maximal cardiopulmonary exercise tests (CPET) are commonly used across clinical populations to make determinations regarding cardiac, pulmonary, and metabolic deficits that may underlie disablement, as well as to stratify the severity of functional impairment. Similarly, maximal CPET has been used in people with ME/CFS. The purpose of this chapter is to introduce the learner to inferences that can be made regarding the pathoetiology of disablement in ME/CFS, based on maximal CPET data.
