Does too much oxygen cause confusion in the elderly?

Answer 1

Too much oxygen can confuse anyone. Our bodies are adapted to atmospheric levels of oxygen, which is about 21% of the air we breathe. Oxygen from inside of one of those pressurized canisters is usually present in much higher concentrations, generally speaking it is usually pure oxygen. So yes, elderly people who are on oxygen can experience some side effects, including headaches, increased sleepiness, and confusion. If any of these seem to be an issue, its is important to contact your physician, as the flow rate or concentration of the oxygen may need to be adjusted.
