Fig. 3From: Pupil maximum constriction velocity predicts post-induction hypotension in patients with lower ASA status: a prospective observational studyScatter plots demonstrating the associations between MCV and CR with decreases in MAP relative to baseline following general anesthesia induction. MCV: Maximum Constriction Velocity, CR: Constriction Ratio (%), \(CR=\left(\frac{MPD}{BPD}\right)\times 100\%\)  Back to article page
