Depends: In some patients with severe copd, the drive to breathe depends on the oxygen level and not the carbon dioxide level. Normally, the level of carbon dioxide in the blood is a very potent stimulus for breathing. But in people with severe copd, this stimulus is blunted because the carbon dioxide level is high for a long time. Thus, the body depends on oxygen levels. This is not very common, though.
