Rorkes/Matt,
Stabilising or improving PEFR is a good thing.
"greater variability in daily PEFR measurements in patients with severe to very severe COPD (with similar comorbidities, age, medication use, and symptoms) could help to objectively identify patients with more unstable disease with a propensity for greater exacerbation and a higher mortality."
