WebOxyhemoglobin is the normal, oxygen-carrying form of hemoglobin in which iron is in the reduced (ferrous) state. Methemoglobin is a nonfunctional form of hemoglobin in which ferrous iron is oxidized to ferric iron. Methemoglobin is nonfunctional because it cannot bind oxygen. In healthy animals, approximately 1% of oxyhemoglobin is converted to ... WebWe examined the relationship between venous and arterial hemoglobin in healthy subjects during rapid volume expansion with isotonic fluid. Methods: Four time-matched venous and arterial hemoglobin samples were collected from healthy volunteers aged 18-30 years during hemodilution with Isolyte® (40cc/kg) following phlebotomy of 1 unit whole blood.
