Abstract |
To observe the relationship between oxygen consumption and body temperature during cardiopulmonary bypass, the authors checked nasopharyngeal and rectal temperature, hemoglobin, and arterial and venous blood gas analysis. At the time when nasopharyngeal and rectal temperatures were equal, it was shown that oxygen consumption had a good relationship (r=0.78) with body temperature. From this data it was revealed that oxygen consumption decreased with decreasing temperature at the rate of about 0.16 ml/kg/min/C. |
Key Words:
