From: Nebulization of the acidified sodium nitrite formulation attenuates acute hypoxic pulmonary vasoconstriction

Figure 4

Impact of nitrite nebulization on the concentration of exhaled NO in the isolated perfused lung model. (A) Exhaled NO was monitored online from the exhaled gas mixture. (B) Hypoxic challenges induced a rapid and reversible decrease in NOex. Nitrite nebulization increased NOex during the hypoxic phase. Values represent the difference between NOex concentrations during hypoxia and during the preceding normoxic phase. * p < 0.05 vs. PB, # p < 0.05 vs. nitrite.
