The sole purpose of Chemically Altered Hemoglobin is to increase the oxygen supply to the body. This is accomplished by researchers chemically connecting tow of the four peptide chanis found within hemoglobin. Such tests, when performed on animals, have been very successful. At both low (10 degrees C) and common body temperatures, it has been shown that Chemically Altered Hemoglobin delivers more oxygen to the body's tissues than unaltered hemoglobin can. (The affect of temperature changes in the hemoglobin is relevent to heart surgeries in which a patient's body temperature is often lowered.) Chemically Altered Hemoglobin will not fragment in the blood, even though unaltered hemoglobin does.

bacterial endotoxins
poisons that are created by certain bacteria and are released upon the destruction of that bacterial cell
Unfortunately, Chemically Altered Hemoglobin retains its ability to transmit disease to the reciever of this substitution. In addition, bacterial endotoxins adhere to altered hemoglobin. Lastly, this hemoglobin would not be located in erythrocytes, as natural hemoglobin is; it would be free within the blood. Some research shows that hemoglobin that is not contained in erythrocytes can constrict blood vessels, which would make the delivery of oxygen to the body's tissues more difficult than if the Chemically Altered Hemoglobin has never been used at all. So although more oxygen would be available for use, the body would not benefit from it's presence.
