Can Too Much Oxygen Make You Sleepy?
My Grandma who is 80 years old, with COPD/emphysema is usually on 3 liters of oxygen. She has had trouble keeping her sats above 90 today. She is also really sleepy. Could this be too much oxygen?
I think it is more likely that she is sleepy because she doesn't have a high enough oxygen sat due to her COPD.
