Blood Oxygenation Comparison Between SNP and Epinephrine During CPR
Alveolar-arterial (A-a) gradient (A) and arteriovenous oxygenation gradient (B) over the 30 min of CPR. All parameters are statistically significant between treatment groups after the 20-min CPR time mark. A-a gradient values are unitless. The 10-min CPR directly precedes intervention of SNP or epinephrine administration. The p values of treatment for A-a gradient and arteriovenous oxygenation gradient is <0.001 and 0.004, respectively. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001. Abbreviations as in Figures 1 and 2.
