Figure 5From: Nebulization of the acidified sodium nitrite formulation attenuates acute hypoxic pulmonary vasoconstrictionChanges in nitrite and nitrite/nitrate (NOx) concentration in perfusate after nebulization. Perfusate samples were collected as depicted in Scheme 1. Samples were immediately frozen and stored at -20°C until analysis. Measurements were performed using a modified Griess reagent according to manufacturer's instructions. (A) Changes in nitrite concentration in recirculating perfusate. (B) Changes in NOx concentration in perfusate.Back to article page
