Incidence and risk factors for potentially suboptimal serum concentrations of vancomycin during cardiac surgery

Figure 1 Distribution of patients without serum samples with a vancomycin level < 10 mg/L and of those with 1 or more serum samples with a vancomycin level < 10 mg/L during cardiac surgery.

Figure 2 Distribution of patients according to the duration of vancomycin infusion. The target time for the duration of vancomycin infusion is 60 min.
