Figure 4:

Example of Continuously Derived Bilateral Non-Invasive Cerebrovascular Reactivity Indices

a.u. = arbitrary units, COx_L = cerebral oxygenation index (correlation between rSO2_L and MAP), COx_R = cerebral oxygenation index (correlation between rSO2_R and MAP), MAP = mean arterial pressure, rSO2_L = regional cerebral oxygen saturations (Left), rSO2_R = regional cerebral oxygen saturations (Right), % = percent. Figure displays 10-second moving average data, with bilateral COx indices derived using the moving correlation between slow-waves in rSO2 and MAP, updated every 10-seconds for this case example.
