Methemoglobinemia
Methemoglobinemia (or methaemoglobinaemia) is a disorder characterized by the presence of a higher than normal level ofmethemoglobin (metHb) in the blood. Methemoglobin is an oxidized form of hemoglobin that has a decreased affinity for oxygen, resulting in an increased affinity of oxygen to other heme sites and overall reduced ability to release oxygen to tissues. The oxygen–hemoglobin dissociation curve is therefore shifted to the left. When methemoglobin concentration is elevated
