Bond Oxygen vs Dissolved Oxygen

There are two types of Oxygen in the body – Oxygen which is bound to hemoglobin and Oxygen which is dissolved freely in the blood. Normal respiration only involves transport of Oxygen which is bound to hemoglobin. However, because hemoglobin is larger than the size of most capillaries in such vital organs as the lungs, Kidneys, Liver and Skin hemoglobin – bound the Oxygen transport is not sufficient to attain full – body circulation

Bond Oxygen vs Dissolved Oxygen

If the atmospheric pressure of Oxygen is high, Oxygen will not readily bind with hemoglobin in red blood cells, the content of dissolved Oxygen will be increased, transport across capillary walls will efficient, free movement into the smallest areas of the circulatory system will become easier, and cellular activity will also be increased

Hyperbaric Oxygen Treatment (HBOT) involves breathing pure oxygen at higher than atmospheric pressures in an enclosed chamber. This process causes oxygen to be absorbed by all body fluids and by all body cells and tissues, even those with blocked or reduced blood flow. This increased flow of oxygen stimulates and restores function to damaged cells and organs, including those of the liver and brain.

The air we normally breathe contains 21% oxygen, 78% nitrogen, with the remaining 1% being contributed by the noble gases and carbon dioxide. The concentration of these gases is determined by the atmospheric pressure which is determined by the weather and is reduced at altitude. Unfortunately the variations in this pressure are ignored in general medical practice. Atmospheric pressure is accorded the unit 1 to represent atmospheric pressure absolute (1 ata) and this unit is divided according to the percentages of the gases in air to give their ‘partial pressures’ that is the part of the total pressure each gas is responsible for – oxygen therefore being 0.21 ata (21% of 1) and nitrogen 0.78 ata (78% of 1).
