Na+ (mmol/L)	141 [139, 144]	140 [138, 143]	0.11
Glucose (mg/dL) (n = 416, 704)	181 [153, 212]	170 [141, 197]	<0.001
K+ (mmol/L) (n = 417, 700)	3.8 [3.5, 4.2]	3.9 [3.5, 4.2]	0.14
Ca++ (mmol/L) (n = 416, 704)	1.23 [1.09, 1.37]	1.21 [1.08, 1.33]	0.029
Lactate (mmol/L) (n = 406, 699)	2.1 [1.5, 3.0]	1.9 [1.5, 2.9]	0.12

Values shown are number (percent) or median [25th, 75th percentiles].

¹pH on bypass was measured at 37 °C (alpha-stat) for all cases performed at >30 °C. pH on bypass was measured at the target temperature (pH-stat) for all cases ≤30 °C.
