The affinity of hemoglobin for oxygen.
The delivery of oxygen to the cell depends in good measure upon the affinity with which hemoglobin binds oxygen or releases it from erythrocytes for use by the other cells of the body. The release of oxygen by normal human hemoglobin A, over a range of partial pressures of oxygen, may be represented graphically by the familiar, sigmoid-shaped, oxygen dis-sociation curve. Numerically, the affini...

متن کاملOxygen Affinity of Hemoglobin in Persons
THE OXYGEN affinity of hemoglobin (Bohr effect)1 may vary in different subjects. Under conditions of organ ischemia, these variations may be of significance. A study was undertaken to assess the affinity of hemoglobin for oxygen among patients in various states. Included in the study were patients with typical acute myocardial infarction, subjects with clinical and electrocardiographic signs of...
متن کاملThe oxygen affinity of sickle hemoglobin.
The right-shifted oxyhemoglobin dissociation curve of sickle cell disease (SCD) has been thought to result in abnormally low arterial oxygen saturation (S(o)(2)), even when oxygen partial pressure (P(o)(2)) is normal. However, without polymer formation (minimal under normoxic conditions), HbS oxygen affinity is normal. We hypothesized that in SCD, in vivo S(o)(2) is normal when P(o)(2) is norma...
