Study Notes

Pulmonary Function Test

  • Used to diagnose and monitor asthma, COPD, and other lung diseases
  • Provides information on whether disease is restrictive or obstructive
  • Usually done using spirometry

Pulmonary Function Test Values

  • FVC (Forced Vital Capacity): the volume of air that you can forcibly exhale in 1 breath
  • FVC normal range value is greater than 80% predicted
  • FEV1 (Forced Expiratory Volume in 1 second): the volume of air that you can forcibly exhale in 1 second
  • FEV1/FVC: ratio of FEV1 to FVC
  • PEFR (Peak Expiratory Flow Rate): the maximum rate at which air flows out of the lungs

Reversibility in Lung Function

  • Measured by an increase in FEV1 or FVC after the administration of bronchodilators
  • Criteria for bronchodilator reversibility: an increase of 12% and 200 mL in FEV1 or FVC over baseline values
  • Used to distinguish between asthma and COPD

Bronchodilator Reversibility Test

  • Measures how reversible the airway obstruction is
  • Helps distinguish between asthma and COPD
  • Asthma is reversible, while COPD is not reversible
  • Steps to perform the test:
    • Do spirometry testing and obtain baseline FEV1 and FVC values
    • Administer a short-acting bronchodilator (such as albuterol) and wait 10 minutes
    • Repeat spirometry

Clinical Implications

  • Reversibility testing is essential in pulmonary function testing
  • The diagnosis and classification of severity of COPD are based on post-bronchodilator spirometry
  • Administration of bronchodilators is still required as part of pulmonary function evaluation
  • Information obtained from BDR testing should be used to inform treatment decisions and disease management

Asthma Treatment

  • Non-Pharmacological:
    • Smoking cessation
    • Reducing secondhand smoke exposure
    • Keeping pets outdoors
    • Removing carpets
    • Using pillow and mattress covers
    • Using a dehumidifier to reduce mold and dust mites
    • Using HEPA filters
    • Avoiding occupational exposures (using appropriate PPE)
    • Masking and vaccinating to prevent respiratory illnesses
    • Pretreating with bronchodilators before exercising
  • GINA Guidelines 2023:
    • Track 1: Preferred controller and reliever using ICS-formoterol as the reliver reduces the risk of exacerbations compared with using SABA reliever and as a simpler regimen
    • Track 1 Steps 1-2: As needed only low dose ICS-formoterol
    • Step 3: Low dose maintenance ICS-formoterol
    • Step 4: Medium dose maintenance ICS-formoterol
    • Step 5: Add on LAMA and consider high dose maintenance ICS-formoterol
    • Reliever: As needed low dose ICS-formoterol
