Blood oxygenators circulation

Oxygenator An apparatus by which oxygen is introduced into the blood during circulation outside the body, as during open heart surgery. [NIH]... 

Oximetry refers to the determination of the percentage of oxygen saturation of circulation arterial blood. Oxygen saturation is defined as follow ... 

Fainting is another reaction to the heat. As blood is circulated to the skin surface and extremities to aid in cooling body temperature, it can accumulate in the lower part of the body if the person is standing still. When less oxygen and blood reaches the brain, fainting can occur. 

Hemoglobin in blood dynamically circulates through the whole body and delivers oxygen from the lungs to terminal tissues. The hemoglobin solution... 

Another consequence of the effect of pressure on gas solubility is the painful, sometimes fatal, affliction known as the bends. This occurs when a person goes rapidly from deep water (high pressure) to the surface (lower pressure), where gases are less soluble. The rapid decompression causes air, dissolved in blood and other body fluids, to bubble out of solution. These bubbles impair blood circulation and affect nerve impulses. To minimize these effects, deep-sea divers and aquanauts breathe a helium-oxygen mixture rather than compressed air (nitrogen-oxygen). Helium is only about one-third as soluble as nitrogen, and hence much less gas comes out of solution on decompression.
