ABSTRACT:
A method and system for measuring the oxygen carrying capacity of normal and abnormal hemoglobins and red cells under controlled pH, ionic strength, temperature and gas conditions is described. A blood sample and a physiologically balanced medium are placed in a cuvette and means are associated therewith for measuring the fractional saturation of the sample and the partial pressure of the oxygen (sometimes referred to as the oxygen tension) and provide output signals to an X-Y plotter for continuous recording. Preferably, means for maintaining the temperature of the medium and the blood sample is provided.
