Alternative Names COPD; Chronic obstructive airway disease; Chronic obstructive lung disease Causes, incidence, and risk factors The leading cause of COPD is smoking. Between 15% and 20% of long-term smokers will develop COPD. Prolonged tobacco use causes lung inflammation and destroys air sacs in the lungs. (In rare cases, an enzyme deficiency called alpha-1 anti-trypsin deficiency can cause emphysema in non-smokers.) Other risk factors for COPD are exposure to secondhand smoke, male gender, and working or living in a polluted environment. Symptoms Shortness of breath (dyspnea) persisting for months to years Wheezing Decreased exercise tolerance Cough with or without phlegm Signs and tests An examination often reveals increased work involved in breathing: nasal flaring may be evident during air intake, and the lips may be pursed (the shape lips make when you whistle) while exhaling. During a flare of disease, chest inspection reveals contraction of the muscles between the ribs during inhalation (intercostal retraction) and the use of accessory breathing muscles. The respiratory rate (amount of breaths per minute) may be elevated, and wheezing may be heard through a stethoscope. A chest X-ray can show an over-expanded lung (hyperinflation), and a chest CT scan may show emphysema. A sample of blood taken from an artery (arterial blood gas) can show low levels of oxygen (hypoxemia) and high levels of carbon dioxide (respiratory acidosis). Pulmonary function tests show decreased airflow rates while exhaling and over-expanded lungs. Treatment Treatment for COPD includes inhalers that dilate the airways (bronchodilators) and sometimes theophylline. The COPD patient must stop smoking. Continue reading this article

Pulmonary atresia (Doctor-Reviewed information)
Pulmonary atresia is an extremely rare form of congenital heart disease in which the pulmonary valve does not form properly. The pulmonary valve is a flap-like opening on the right side of the heart that allows blood to move to the lungs. In pulmonary atresia, a solid sheet of tissue forms where the valve opening should be. Because of this defect, blood from the right side of the heart cannot go to the lungs to pick up oxygen.
