Exacerbations of COPD at home
TX |
1. Increase dose/frequency of short beta-2 agonist (SABA). If not on anticholinergic, add anticholinergic .
2. If baseline FEV1< 50% of predicted, short course of oral steroid (30-40mg prednisolone/day x 7-10 days) OR if condition not severe (i.e.; patient is not acidotic) consider nebulized budesonide |
|
Hospital management of exacerbation
|
1. SABA
