This is a an urban myth. Casinos DO NOT pump in oxygen to the casino. For one reason (and probably the most important) it is illegal! A felony, actually (IANAL).
Secondly, it is a fire hazard. An oxygen rich environment will cause any fire to be accelerated, even if only a little.
Thirdly, considering the amount of air exchanged each hour, an incredible volumn of oxygen would be necessary to make a difference. This would also mean special equipment, more staff, etc.. It would be incredibly expensive, and the risk/reward ratio is just too small. Actual casino interior/exterior design (besides location) is the single most important factor in drawing patrons.
The truth is that a MASSIVE amount of air is replaced each hour. The casino has huge air handlers that keep the air free from smoke. They sometimes add scents to the air to keep it smelling fresh. A typical casino can exchange the entire volumn of air in the casino several times an hour. This, of course, gives the impression that oxygen is being pumped in because it smells so fresh and clean.
Yes, casinos pump oxygen into the air so they can keep people awake so they keep gambling thus the casino receives more money.
If there is a problem with us breathing oxygen, we all have a very big problem. The Earth's atmosphere is composed of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. It is common practice in trauma treatment to supplement additional oxygen to the patient. Finally, it is a common practice in casinos to pump in more oxygen. Perhaps you want to look at your data and rethink your question.

Smog Pump is the slang term used for a oxygen pump on a car/truck.
The amphibian's heart does pump out a mixture of oxygen-rich and oxygen-poor blood. They are vertebrates, and this is how vertebrates' circulatory systems work.

Smog Pump is the slang term used for a oxygen pump on a car/truck.
the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
When you are exercising, you are breathing in oxygen (O2) and it is get the heart to pump more blood to your body
