Primary outcomePrimary: Mean Variability in Peak Inspiratory Flow (PIF) — 67.6 Liters/minute
Summary
This is a multi-center 3-month study to determine the variation in ProAir Digihaler metrics [peak inspiratory flow (PIF), inhalation volume, number of inhalation events] amongst COPD patients in the ambulatory setting.

Eligibility Criteria
Inclusion Criteria
- Age >40 years old
- History of cigarette smoking >=10 pack-years
- Established COPD defined as physician diagnosis along with spirometry confirmation [post-bronchodilator (BD) forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC)<0.70] within the last two years and an FEV1 ≤80% predicted
- Regular albuterol use (defined as at least one puff weekly for each of the last four weeks)
- Currently non-hospitalized
- Medical records confirmed history of two moderate AECOPD (defined as use of antibiotic or steroids to treat clinical event consistent with AECOPD) or one severe AECOPD (defined as emergency department/hospital visit) in prior 12 months
- Access to smart phone, tablet or computer and internet
- Willingness to switch current rescue inhaler/device to ProAir Digihaler
Exclusion Criteria
- Allergy or inability/contraindication to use Albuterol Sulfate
- Any condition that, in the opinion of the site investigator, would compromise the subject's ability to participate in the study
