What is COPD ? Chronic Obstructive Pulmonary Disorder (COPD) is one of the most common lung diseases. Smokers are prone to developing COPD, although nonsmokers can get it too; if they lack a protein called alpha-1 antitrypsin. There are two main forms of COPD: Chronic bronchitis, which involves a long-term cough with mucus. Emphysema, which involves destruction of the lungs over time.

Diagnosis information Medical history and examination is used to diagnose COPD. If someone in the family has this disease, than it can be passed down through genetics. Physical examinations may show a barrel chest, decreased breath sounds, and wheezing. The most reliable way to diagnose this disease would be spirometry.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
