Algorithm of procedures applied in the decline in the value of NIRS cerebral oximetry. ScrO2 – local saturation of the cerebral cortex; MAP – mean arterial pressure; SaO2 – oxygen saturation of arterial blood; Hb – hemoglobin; CO – cardiac output; ScvO2 – central venous oxygen saturation; CMRO2 – cerebral metabolic rate of oxygen; ICP – intracranial pressure.

Graph of MAP (mean arterial pressure), NIRS1 and NIRS2 (near infrared spectroscopy – cerebral oxygen saturation) correlations in a 32 year – old woman participating in the study. A positive correlation between the recorded parameters was detected.

5. Fig. 4
Graph of MAP (mean arterial pressure), SpO2 (systemic pulse oximetry saturation), NIRS1 and NIRS2 (near infrared spectroscopy – cerebral oxygen saturation) correlations in a 60 year-old woman participating in the study. No positive correlation between the recorded parameters was detected. The arrow indicates unilateral decreases in the value of NIRS2 despite increases in MAP. SpO2 values remain unchanged, despite the fluctuations in the value of NIRS.

Graph of MAP (mean arterial pressure), NIRS1 and NIRS2 (near infrared spectroscopy – cerebral oxygen saturation) correlations in a 60 year – old man participating in the study. The arrow indicates the decrease in MAP with no decreases detected in the value of NIRS.

7. Fig. 6
Graph of MAP (mean arterial pressure), NIRS1 and NIRS2 (near infrared spectroscopy – cerebral oxygen saturation) correlations in a 29 year – old woman participating in the study. The arrow indicates the decrease in MAP during which no declines in the value of NIRS were detected.
