Assessment of Systemic and Cerebral Oxygen Saturation during Diagnostic Bronchoscopy: A Prospective, Randomized Study

Figure 1

Absolute values of systemic and cerebral oxygen saturation at baseline (0 sec) and averaged values during bronchoscopy (mean). Means and standard deviations are shown. 2 l and 4 l indicate 2 l/min and 4 l/min supplemental oxygen administration.
