COPD. COPD has many treatments -- first and foremost, the patient must quit smoking (if they are a smoker). The next line of treatment includes inhalers. There is a newer pill that is available to prevent COPD exacerbations, but this is often not used first line. Oxygen supplementation is used in the more severe forms of copd.
Treatment... COPD is treated with bronchodilator and steroid inhalers. Smoking cessation is a necessary part of treatment. Oxygen therapy is given if the oxygen level is low. There is no cure for COPD but, with therapy, the symptoms can be controlled. Additional therapies depend on the symptoms present. See your doctor for treatment!
