Relationship between acute hypercarbia and hyperkalaemia during surgery

Figure 1 pH-dependent ion channels involved in potassium homeostasis of a skeletal muscle cell.

Figure 2 Box and Whisker plots. A: Changes in plasma potassium measured at baseline and at 15 min; B: Changes in plasma potassium over time. Repeated measures ANOVA, P = 0.95; C: Changes in arterial carbon dioxide at baseline and at 15 min; D: Box and Whisker plots with changes in arterial carbon dioxide over time. Repeated measures ANOVA, P < 0.0001.
