Multicenter Study Comparative Study
Spirometric correlates of dyspnea improvement among emergency department patients with chronic obstructive pulmonary disease exacerbation.
To examine whether change in slow vital capacity (SVC) correlates to dyspnea improvement during emergency department (ED) treatment of chronic obstructive pulmonary disease (COPD) exacerbation. ⋯ Increase in SVC significantly correlated with dyspnea improvement among ED patients with moderate-to-severe COPD exacerbation. Change in SVC merits consideration when evaluating therapeutic response during COPD exacerbation.
