Blood gas tension constant 0.0031 represents the amount of oxygen dissolved in plasma. The dissolved-oxygen term is generally small relative to the term for hemoglobin-bound oxygen, but becomes significant at very high PO (as in a hyperbaric chamber) or in severe anemia. This is an estimation and does not account for differences in temperature, pH and concentrations of 2,3 DPG. Blood gas tension Blood gas tension refers to the partial pressure of gases in blood. There are several significant purposes for measuring gas tension; the most common gas tensions measured are oxygen tension (PO), the carbon dioxide tension (PCO) and carbon monoxide tension
Blood doping used by cyclists in combination with cobalt chloride/desferrioxamine stimulate and de-regulate the natural production of erythropoietin hormone. At physiologically low PaO around 40 mmHg, EPO is released from the kidneys to increase hemoglobin transportation. The combination of drugs consistently releases EPO due to increased transcription at the cellular level. The effect wears off when the HIF stabilizers, cobalt chloride/desferrioxamine is excreted and/or decayed by the body. Myo-inositol trispyrophosphate (ITPP), also known as compound number OXY111A, is an allosteric effector of hemoglobin which causes a rightward shift in the oxygen–hemoglobin dissociation curve, increasing the amount of oxygen released from red blood
