Abstract:
Temperature-dependent spectral changes of human haemoglobin A (HbA) derivatives were investigated in the range 20-40 degrees C. The intensity of the deoxy-HbA decreased by 3-3.5%, while that of oxy- and met-HbA by less than 1%, when the temperature increased from 20 degrees to 40 degrees C. The present findings can be employed to improve the algorithms used in in vivo near infrared spectroscopy.
