Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Using various types of inhalers is the treatment cornerstone for COPD patients to control their symptoms. Many inhaler devices require minimum inspiratory effort to activate the device, COPD patients commonly use such devices. Those devices deliver the medications only when the patient forcefully inhales so the drug can reach the lungs, thus exerting their therapeutic action. The effect of appropriate use of the inhalers in patients with COPD is not well studied, and the impact of demonstrating that a patient can inhale forcefully enough to activate a device on its' effect on symptoms is also lacking in the medical literature. The purpose of this study is to find out: 1. the frequency of COPD patients demonstrating an appropriate use of inhalers that have flow-triggered systems, 2. whether the appropriate use of inhalers impacts the Quality of Life and Shortness of Breath of COPD patients, and 3. the impact of appropriate use of inhalers on FEV1 in COPD patients.
