Bias: difference between CI Aesculon and CI Vigilance. CI: 95% confidence interval. LOA: limits of agreement. Time point () 1 prior to surgery, after induction; prior to cannulation of the aorta;   10 minutes after protamine administration; 30 minutes after arrival at the ICVU ward; one hour after extubation at the ICU ward; on day one postoperatively at 8:00 a.m. in the ICU ward.
