Shown is the mean (± SE) etCO2 (mmHg) of rats treated with systemic L-NAME or D-NAME and SS-RBCs or AA-RBCs. The LN-SS stroke group etCO2 was significantly lower than the other experimental groups beginning 10 minutes after the completion of the RBC infusion (*P < .05) and significantly different from baseline levels within the same group (time = 0) beginning 15 minutes after the completion of the RBC infusion (†P < .05).
