Deming fit (solid blue line) for sodium ion levels. The sodium ion levels determined using the arterial blood gas analyzer (ABGA) are presented on the X-axis, while the sodium ion levels determined using the chemistry are presented on the Y-axis. Deming regression equation: chemistry Na (mmol/L) = 20.7 + (0.9 × ABGA Na [mmol/L]), R 2 = 0.43
