Chronic obstructive pulmonary disease (COPD) is one of the most common lung conditions in the world. It’s known for developing slowly over the course of many years, leading to increased breathlessness, chest pain, coughing, and wheezing. As this incurable disease progresses, flare-ups and exacerbations become more common, so COPD patients need to pay especially close attention to the treatment plan created by their doctor. Since a core aspect of most treatment plans involves supplemental oxygen therapy, it’s also important for COPD patients to find an oxygen device that serves their long-term goals.
