Inspiratory capacity manoeuvres and flow-volume loops are increasingly being used to characterize ventilatory limitations during cardiopulmonary exercise testing (CPET). Accurately measuring inspiratory capacity is essential when examining dynamic hyperinflation and if using flow-volume loops to measure expiratory flow limitation and other ventilatory abnormalities during exercise. This presentation will discuss key methodological factors to maximize the accuracy of these measurements and to ensure correct CPET interpretation.

Learning Objectives
At the end of this presentation, attendees will be able to:

  • Determine how to accurately measure, analyze and interpret inspiratory capacity manoeuvres during CPET; and
  • Critically evaluate the factors involved in generating exercise flow-volume loops and determine how key errors can affect your interpretation.
