TREATMENT BY PFT EVALUATION
Stage I: Mild
FEV1/FVC < 70%
FEV1 = >= 80% predicted
TREATMENT
SABA or inhaled anticholinergic (tiotropium) PRN
Stage II: Moderate
FEV1/FVC < 70%
FEV1 = 50-79% predicted
SOB on exertion
TREATMENT
regular use of LABA
consider combining LABA + long-acting anticholinergic
Stage III: Severe
FEV1/FVC < 70%
FEV1 = 30-49% predicted
SOB on exertion
frequent exacerbations
TREATMENT
add inhaled steroids
consider combining steroid + LABA (fluticasone + salmeterol)
Stage IV: Very Severe
FEV1/FVC < 70%
FEV1/FVC < 30% predicted or <50% predicted + chronic respiratory failure
TREATMENT
add long term O2 therapy if justified
consider lung reduction surgery (emphysema)
