Document Summary
Case study: a 65-year old man presented with one-week history of. Shortness of breath due to mucus in the bronchioles. Cough (productive loose yellowish and somewhat foul smelling sputum) A feeling of pain in the chest when inhaling during normal breathing: nerves in the pleura are irritated (plueritis) Is feeling generally very weak due to some hypoxia: on examination: Indicates some solidification in the lungs: diagnosis: pneumonia (lung infection, next step. Two ways to do it: choose the drugs that affect common infectious organisms, specifically identify the organism and then give appropriate drug. Alveolar = pmn leukocytes are in the alveolus. May be focal or diffuse, and unilateral. Usually bacterial, may be due to other. Focal = confined to terminal bronchioles or the bronchi. Interstitial pneumonia = inflammation of the alveolar septae (or interstitium) due inflammatory cells invading the alveolar septae. Does not result in exudation in the alveolar spaces. Causes of pneumonia 75% are caused by bacteria.
