Reliability data [Intraclass Correlation Coefficients (ICC), Confidence Intervals (CI), and Typical Error of the Measurement (TEM)] collected during the Pilot Study for pH and ${\text{sHCO}}_3^{-}$ measures obtained from the ABL 80 Flex (Radiometer, Copenhagen, DK).

Within-sample reliability	ICC (95% CI)	TEM (95% CI)
pH (au)	0.76 (95% CI 0.66 to 0.84)	0.02 (95% CI 0.02 to 0.04)
${\text{sHCO}}_3^{-}$ (mmol·L−1)	0.99 (95% CI 0.98 to 0.99)	0.4 (95% CI 0.3 to 0.5)
Week-to-week variability	ICC (95% CI)	TEM (95% CI)
pH (au)	0.30 (95% CI 0.04 to 0.59)	0.04 (95% CI 0.03 to 0.05)
${\text{sHCO}}_3^{-}$ (mmol·L−1)	0.77 (95% CI 0.59 to 0.89)	1.5 (95% CI 1.2 to 1.9)
