BLOOD GAS ANALYSIS FROM NEONATAL β-EPITHELIAL NA⁺ CHANNEL–OVEREXPRESSING MICE AND WILD-TYPE LITTERMATES^*

Genotype	pH	Pco2 (mm Hg)	Po2 (mm Hg)	HCO3− (mmol/L)	BE (mmol/L)	Sat O2 (%)
Wild-type	7.42 ± 0.01	48.7 ± 1.7	49.9 ± 2.0	30.8 ± 0.6	5.6 ± 0.5	83.7 ± 1.8
βENaC overexpressing	7.40 ± 0.01	48.8 ± 1.4	43.1 ± 2.4†	29.2 ± 0.6	3.8 ± 0.5†	77.0 ± 2.4†

Definition of abbreviations: BE = base excess; βENaC = β-epithelial Na⁺ channel; Sat O₂ = O₂ saturation.

^*n = 8–14 mice per group.

^†P < 0.05 compared with littermate control mice.
