Figure 4From: Parenteral diclofenac infusion significantly decreases brain-tissue oxygen tension in patients with poor-grade aneurysmal subarachnoid hemorrhageCorrelation between P b tO 2 (x) reaching minimum values after parenteral diclofenac and P b tO 2 values before intervention. Lines represent PbtO2 threshold of 20 mm Hg. The right lower quadrant indicates PbtO2 values ≥20 mm Hg at baseline reaching hypoxic values after intervention.Back to article page
