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
Hemoglobin D-Punjab Angeles”. Hemoglobin D is the 4th most common hemoglobin variant. It developed as a response to the selective pressures of malaria in these regions of Asia. Hemoglobin is the main ingredient in red blood cells. People with hemoglobin D trait have slightly more hemoglobin A than hemoglobin D. People with Hemoglobin D trait do not have health problems related to having the trait. People with hemoglobin D trait do not have Hemoglobin D disease or sickle cell disease. They cannot develop these diseases later in life. Hemoglobin helps red blood cells carry oxygen from the lungs to other parts of
