Session Description

It is increasingly recognized that adults with preserved ratio impaired spirometry (PRISm) lung function patterns are prone to increased morbidity. This talk will review the current state of knowledge on the physiology of PRISm.  Emerging evidence interrogating the physiological responses to cardiopulmonary exercise testing, and the mechanisms of exertional dyspnea and exercise intolerance in PRISm will be discussed.

Learning Objectives

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

  • Identify pulmonary function patterns consistent with PRISm
  • Compare and contrast PFT and CPET patterns in PRISm versus COPD
  • Summarize the basic neurophysiological constructs of dyspnea
  • Summarize the known pathophysiological mechanisms of activity-related dyspnea in PRISm
