Document Summary
Allergic reaction/chest constriction= difficulty breathing caused by constriction of smooth muscle around brochus/bronchioles. Pneumonia-induced buildup of fluid/pus + inflammation of alveoli= inhibit gas exchange (decrease in gas exchange efficiency) Pleurisy= disorder of pleura when visceral and parietal membranes rub against each other and therefore become inflamed= severe chest pain with every breath. Thoracotomy= needle in chest to remove pressure and tube implanted to remove air. Haemothorax= blood in the pleural space due to physical trauma= diagnosed by x-ray or ct scan= treated with a chest tube to drain the blood. Asbestosis= long term inhalation of small asbestos fibres which scar lung tissue= accumulate in pleural space/alveoli= chronic chest pain and breathing pain= can result in lung cancer or cancer of the pleura (mesotheloma) Restrictive pulmonary disorder= interfere with lung expansion and therefore inspiration= caused by damage to chest wall/lungs/pleura= for example. Pulmonary edema (expansion of alveoli inhibited by fluid in the lungs) or pulmonary fibrosis= increase in fev1/fvc ratio.
