[Dynamics of the measured oxidative potential of preserved blood]

An expression for oxidative potential (phi) of conservated blood is suggested proceeding from the assumption of the steady character of the system methemoglobin -- hemoglobin, oxihemoglobin included. This system is suggested to be responsible for the formation of phi in the blood. The equation qualitatively describes the experimental relation of phi on time at the contact of blood with air. Relationship between the changes of oxidative potential in the blood during its storage with the state of conservated blood hemoglobin is discussed. The experimental data show that measuring of the oxidative potential may be the basis for creating a control method for the state of conservated blood during its storage.
