== Diagnostic Criteria (CTS 2017) ==

=== Required Criteria ===

# Diagnosis of COPD based on risk factors, history, and spirometry
# History of asthma, either as a past history or as current symptoms and spirometry consistent with asthma
# Spirometry showing post-bronchodilator fixed FEV1/FVC <0.7

=== Supportive Criteria ===

* Bronchodilator improvement in FEV1 of 12% and 200 mL
* Sputum eosinophils >3%
* Blood eosinophils > 300 cell/uL

== Management ==

* Same non-pharmacologic/preventative management as both COPD and asthma
* For puffers, try to use ones that are good in both
** Don't use LABA monotherapy (b/c not good in asthma)
** Don't use inhaled steroid alone (b/c not good in COPD)
* Puffers:
** SABA prn
** Next add ICS/LABA
** Next add LAMA
