  2. Oxygen–hemoglobin dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Oxygenhemoglobin...

    The fetal dissociation curve is shifted to the left relative to the curve for the normal adult because of these structural differences: In adult hemoglobin, the binding of 2,3-bisphosphoglycerate (2,3-BPG) primarily occurs with the beta chains, preventing the binding of oxygen with haemoglobin.

  3. Bohr effect - Wikipedia

    en.wikipedia.org/wiki/Bohr_effect

    Hemoglobin's oxygen binding affinity (see oxygen–haemoglobin dissociation curve) is inversely related both to acidity and to the concentration of carbon dioxide. [1] That is, the Bohr effect refers to the shift in the oxygen dissociation curve caused by changes in the concentration of carbon dioxide or the pH of the environment.

  4. Hill equation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Hill_equation_(biochemistry)

    Plot of the % saturation of oxygen binding to haemoglobin, as a function of the amount of oxygen present (expressed as an oxygen pressure). Data (red circles) and Hill equation fit (black curve) from original 1910 paper of Hill. [6] The Hill equation is commonly expressed in the following ways: [2] [7] [8]

  5. Oxygen saturation (medicine) - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation_(medicine)

    At around 90% (the value varies according to the clinical context) oxygen saturation increases according to an oxygen-hemoglobin dissociation curve and approaches 100% at partial oxygen pressures of >11 kPa. A pulse oximeter relies on the light absorption characteristics of saturated hemoglobin to give an indication of oxygen saturation. [4]

  6. Haldane effect - Wikipedia

    en.wikipedia.org/wiki/Haldane_effect

    In addition to enhancing removal of carbon dioxide from oxygen-consuming tissues, the Haldane effect promotes dissociation of carbon dioxide from hemoglobin in the presence of oxygen. In the oxygen-rich capillaries of the lung, this property causes the displacement of carbon dioxide to plasma as low-oxygen blood enters the alveolus and is vital ...

  7. Shunt equation - Wikipedia

    en.wikipedia.org/wiki/Shunt_equation

    Using the fact that each gram of hemoglobin can carry 1.34 mL of O2, the oxygen content of the blood (either arterial or venous) can be estimated by the following formula: = [] ( /) + PO2 is the partial pressure of oxygen and reflects the amount of oxygen gas dissolved in the blood. The term 0.0032 * P02 in the equation is very small and ...

  8. Oxygen saturation - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation

    In medicine, oxygen saturation refers to oxygenation, or when oxygen molecules (O 2) enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation ((O 2) sats) measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen ...

  9. Dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Dissociation_curve

    Dissociation curve may refer to: Ligand (biochemistry)#Receptor/ligand binding affinity represented in a graph; Oxygen-haemoglobin dissociation curve, a graphical representation of oxygen release from haemoglobin; Melting curve analysis, a biochemical technique relying on heat-dependent dissociation between two DNA strands
