Why is it so dangerous to give large amounts of oxygen to a patient with emphysema?

In brief: Not usually

In the late stages of emphysema or copd, patients do not respond normally to stimuli that make normal patients breathe.
They only keep breathing in response to low oxygen in their bloodstreams. If they are given too much oxygen, their systems think that they don't need to breathe and they can actually breathe less or stop breathing. This is a rare problem. Oxygen helps most emphysema patients.

In brief: Oxygen...

Oxygen is a drug and like any drug, there are side effects if too much is taken.
In a patient with copd, too much oxygen can cause an increase in the carbon dioxide level which will result in the person being sedated and hypoventilating, resulting in higher carbon dioxide levels. Long term, too much oxygen results in more lung damage over time. The lowest amount of oxygen needed should be used.

In brief: Can Be

Some patients can get a rise in their carbon dioxide levels with high doses of oxygen - this doesn't happen in every patient but if it does it can be dangerous.
