Grade and Group
- GOLD grades 1-4 based on FEV1 % of predicted.
- GOLD group based on mMRC, number of exacerbations per year.
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
- O2 goal 88-92%, because they are dependent on hypoxia for respiratory drive, since they are chronically hypercapnic.
