- Protocol
- Obtain baseline Pulmonary Function Tests
- Perform Exercise
- Patient wears nose clip
- Reach 80-90 of maximal Heart Rate within 2 minutes
- Maintain increased Heart Rate for 8 minutes
- Test performed under constant conditions (humidity <50%, air Temperature 60 to 70 F or 20 to 25 C)
- Obtain post-exercise Pulmonary Function Tests
- Minute 1-3 post-Exercise
- Minute 5 post-Exercise
- Minute 10 post-Exercise
- Minute 15 post-Exercise
- Minute 20 post-Exercise
- Minute 30 post-Exercise
- Minute 45 post-Exercise
- Interpretation: Positive test criteria
- FEV1 or FVC declines 10% or more between any 2 consecutive points in the first 30 minutes post-Exercise
- Diagnostics: Eucapnic Voluntary Hyperpnea
- Specialized lung function testing at designated centers (per International Olympic Committee)
- Indicated for olympic level athletes to be approved for Bronchodilator use prior to Exercise
