Oxyhemoglobin dissociation curve

An oxyhemoglobin dissociation curve is a sigmoid plot of percent oxyhemoglobin saturation vs. P_O2. The curve illustrates hemoglobin's affinity for oxygen.

Under normal resting conditions in a healthy individual, the normal position of the curve is at a pH of 7.4.

A shift in the position of the curve with a change in pH is called the Bohr effect.
