<prompt> The right of the oxygen dissociation curve shifted in:Fetal hemoglobin2,3 DPGpHTemperature  <response>: pH4: Ref: 593-H, 581-SL, 667-G, 468-GTN 611- Ganong 23rd Fetal haemoglobin HbF does not bind, 2, 3 D PG, so it tends to have a higher oxygen affinity in vivo, the oxygen hemoglobin curve shifted to left:Right side shift of oxygen - hemoglobin dissociation curve - causes1. Increased CO2 concentration2. Increased temperature Hyperthermia3. Increased 2,3 DPG, DPG is a by product in EMP-pathway of carbohydrates metabolism. It is present in RBC, in conditions like muscular exercise and in high altitude, the DPG increased in RBC, so the oxygen, hemoglobin dissociation curve shifts to right to a great extent4. Decrease in partial pressure of oxygen5. Increase in hydrogen ion concentration and decrease in pH Acidosis6. In anemia, curve is shifted to right side 56-SLLeft side shift of oxygen-hemoglobin dissociation curve1. In fetal blood-because fetal hemoglobin has got more affinity for oxygen than the adult hemoglobin2. Decrease in H concentration and increase in pH Alkalosis3. Hypothermia4. Blood transfusion: - In stored blood, the 2,3DPG levels falls and the ability of this to release 02 to the t issue is reduced, this leads to curve shift to left side The decrease in 2,3DPG can be prevented by adding substance such as inosine hypoxanthine-ribose to storage medium 32- Lippancotts 2nd
