Exacerbation

  • O2 administration improves oxygenation to areas of lung with low V/Q ratio
  • increase in sputum volume, purulence, and dyspnea
  • severe: all 3 present
  • moderate: 2/3
  • mild: 1 of the above, plus another finding such as URI, fever, cough, wheezing
  • treatment depends on severity.

Treatment
