Primary reasons for conducting CPET in patients with ILD.

Reasons for conducting CPET
• Determining the cause(s) of exertional dyspnea
• Assessing functional capacity and the mechanism(s) of exercise intolerance
• Determining the magnitude of exercise-induced hypoxemia
• Establishing a baseline prior to and setting exercise training intensity for pulmonary rehabilitation
• Evaluating the acute and chronic response to pharmacological and non-pharmacological interventions on exercise performance, symptoms, and physiology
• Evaluating pulmonary gas exchange abnormalities
• Patient prognostication
• Determining the presence of co-morbidities
• Evaluation for lung transplantation
