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 C cell crises. The peripheral smear demonstrates mostly target cells and only a few sickle cells. However, persons with hemoglobin SC disease (HbSC) have more significant retinopathy, ischemic necrosis of bone, and priapism than those with pure SS disease. People with hemoglobin C trait, or hemoglobin C carriers, have one gene for HbC and one normal gene. Their red blood cells contain both normal hemoglobin A and also hemoglobin C. People with hemoglobin C trait have slightly more hemoglobin A than hemoglobin C in their cells. Hemoglobin C disease is an autosomal recessive disorder that results from the biparental inheritance of
