Carbon Monoxide is a gas that prevents oxygen from entering the bloodstream, that's the reason why it's so deadly
Oxygen is a gas.
Oxygen gas is made up of one substance = oxygen. So oxygen gas is not a compound
Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
By chemical analysis; also a candle burn in oxygen (or in a gas containing oxygen) but not in nitrogen, argon, carbon dioxide.
When water splits, hydrogen gas and oxygen gas are formed.
Oxygen is the gas that passes from the lungs to the bloodstream.

Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
I don't know of any common cell that uses oxygen gas. The cells that I know of use dissolved oxygen delivered by the bloodstream.
In a way, yes, if there is not enough oxygen getting to it, and there is an excess of non-vital fluids in your bloodstream, your brain could be considered as drowning. Alternatively, if you are inhaling gas that is not oxygen, or another fluid that is not oxygen, your brain could be considered as drowning.
You're likely thinking of oxygen.
When the discharge valve is opened, the CO2 is forced out of the tank by pressure, and changes to CO2 gas. This is a heavy gas that will not burn, and blocks the fire from getting oxygen.
Carbon Monoxide is the gas that is found in cigarette smoke, which binds to the hemoglobin in the red blood cells limiting oxygen supply to your body. However, it is unlikely that you would die from carbon monoxide poisoning due to the fact cigarette smoke does not produce enough parts per million to overrun your bloodstream with the CO gas.
carbon monoxide (CO)
The process in which oxygen enters the bloodstream through the alveolus and carbon dioxide exits the bloodstream also through the same alveolus to be exhaled.
