  1. Chronic Obstructive Pulmonary Disease (COPD)
    1. Lung disease in which it is hard to breathe.

    2. Damage to bronchi partially obstruct them, making it difficult to get air in & out

    3. Usually smokers or former smokers who also have chronic bronchitis & emphysema.
  2. Chronic bronchitis
    1. Airways have become inflamed & thickened

    2. Increase in number & size of mucus-producing cells

    3. Results in excess mucus production, which causes coughing & difficulty getting air in & out
  3. Emphysema
    1. Progressive loss of lung function

    • 2. Characterized by:
    • .....a. Decrease in total # of alveoli
    • .....b. Enlargement of remaining alveoli
    • .....c. Progressive destruction of walls of remaining alveoli

    3. As aveoli are destroyed, breathing becomes inreasingly rapid, shallow & difficult.

    4. To compensate for loss of capacity, the lungs expand, sometimes causing an enlarged barrel shaped chest.

    • 3. Compare to hypoxia - below-normal O2 levels in body tissues & cells
  51. Hypoxia
    1. Condition of having below-normal levels of oxygen in body tissues & cells

    2. Less severe than anoxia.

    3. Compare to hypoxemia - below-normal O2 levels in the blood
  52. Altitude Hypoxia (altitude sickness)
    Condition brought on by the decreased oxygen in the air at higher altitudes, usually above 8,000 feet.
  53. Respiratory failure (respiratory acidosis)
    Condition in which the level of oxygen in the blood becomes dangerously low OR the level of carbon dioxide becomes dangerously high.
  54. Smoke inhalation
    Damage to the lungs in which particles from a fire coat the alveoli & prevent normal exchange of gases
  55. Sudden infant death syndrome (SIDS or crib death)
    1. Sudden & unexplainable death of an apparently healthy sleeping infant between the ages of 2 weeks & 1 year
