The main questions it aims to answer are:\n\nIs OPEP therapy able to improve the impact of cough symptoms as measured on a validated symptom score? Is OPEP therapy able to improve the properties of the lung (called reactance) as measured by oscillometry?\n\nResearchers will compare the results of the same tests performed before and after 4 weeks of OPEP treatment to see if OPEP treatment improves cough symptoms and lung mechanics.\n\n* Participants with COPD will complete in-person baseline tests and will then receive the smart OPEP device.\n* These participants will then use the smart OPEP device at home, at least twice a day, for 4 consecutive weeks.\n* Finally, these participants will return to complete in-person end-of-study tests.", "detailedDescription"=>"The objectives of this prospective, non-pharmacologic interventional cohort study are to determine the effect of four consecutive weeks of twice-daily or greater OPEP usage among patients with COPD with a chronic bronchitis (sputum-producing) phenotype on disease impact and on respiratory system dynamics.
