Measurement of Total Body Hemoglobin by Bloodless Technic

[摘要] The theory and methodology for the determination of total body hemoglobin by Sjostrand's closed breathing technic has been evaluated. The results show that it is possible to determine total body hemoglobin from the measurement of alveolar carbon monoxide concentrations. A system for closed breathing measurement was designed and assembled which permits continuous monitoring of alveolar carbon monoxide and oxygen. Improvements in this system are suggested such that total body hemoglobin may be read out directly, from the determination of alveolar carbon monoxide concentrations, by means of a sensitive infrared analyzer. Such measurements of total body hemoglobin have a high correlation coefficient with measurements of total body hemoglobin made by the Risa (radioiodinated serum albumin) blood volume technic.
