Paper Abstract

For investigation of influence of pulsatile blood volume fluctuations on the saturation measurements more than 10 thousand pulse wave signals for 5 subjects in 20 experiments were measured and the modulation (M), modulation ratio (MR) of the red and infrared light signals, cardiocycle duration (T), correlation (C) between the red and infrared light were determined. There were C > 0.97, for all pulse wave signals, C > 0.995 for 90% of them. Changes of the M within an experiment were from 10 to 100 percents while the MR changed from 1 to 20 percents. The periodical changes of the M, MR, and T which one can associate with a breath rhythm were registered. The M and T changed synchronously. Obtained high C between red and infrared signals, when M spontaneously changed significantly, gives basis to suppose that pulsatile blood volume fluctuation does not effect on MR and arterial blood saturation (SaO2) measured. One could suppose that the periodical changes of MR might be caused by variation of the blood saturation on different phase of breathing process.
