Figure 2From: Incidence of low central venous oxygen saturation during unplanned admissions in a multidisciplinary intensive care unit: an observational studyCentral venous oxygen saturation (ScvO2) trends in the different patient groups. Trends are divided into an intensive care unit admission ScvO2 of less than (a) and greater than (b) 60%. ScvO2 is displayed as mean ± standard deviation. *Student's paired t test, p < 0.05, versus admission ScvO2. CNS, central nervous system; n, absolute number of patients per subgroup.Back to article page
