Oxygen haemoglobin dissociation curve gives the relationship between the saturation of haemoglobin and oxygen tension. The curve obtained by plotting the per cent saturation of Hb against time is sigmoid, at $38^{\circ }\mathrm{C}$ and pH 7.4. Dissociation of oxyhaemoglobin can be promoted by rise in the body temperature and low $\mathrm{pH}($ high ${\mathrm{CO}}_2)$.
