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
