Fetal Hemoglobin

A type of hemoglobin found in fetuses that has a higher affinity for oxygen than adult hemoglobin.

Oxygen-Dissociation Curve

A graphical representation showing the relationship between the oxygen saturation of hemoglobin and the partial pressure of oxygen, important for understanding oxygen transport in blood.

BPG Levels

Refers to the concentration of 2,3-Bisphosphoglycerate, a compound that affects oxygen binding and release from hemoglobin, thereby influencing oxygen delivery to tissues.

Oxygen-Hemoglobin Dissociation Curve

Graph describing the relationship between the percentage of hemoglobin saturated with oxygen and a range of oxygen partial pressures.
