Asthma
Chronic lung disease characterized by airway inflammation, airway and variable expiratory air flow obstruction
There are 2
obstruction: • FEV1 / FVC ... lower • FEV1 / FVC ... Increase of FEV1 or FVC ... greater in FEV or FVC
Forced vital capacity (FVC) curves comparing normal, obstructive, and restrictive disorders. Curves are as they appear

Consensus diagnostic criteria for asthma-COPD overlap syndrome (ACOS) in patients with airflow limitation. COPD=chronic obstructive pulmonary

Asthma vs COPD Presentation and Diagnosis
Asthma:
 • Epidemiology: Age usually < 45, History (personal or family)
spirometry - FEV1/FVC ... spirometry - FEV1/FVC
Management of interstitial lung disease (ILD)-associated with systemic sclerosis (SSc)

Therapeutic indication: absolute decline in FVC >10%
absolute decline in FVC
Pulmonary Function Test (PFT) Interpretation Algorithm

Approach to PFTs:
1) Look at Flow-Volume Loop if available
2) FEV1/FVC <
available 2) FEV1/FVC ... 3) FVC < LLN?
