Figure 2 Response of pulmonary vascular resistance (PVR) and systemic arterial pressure (SAP) to inhalation of treprostinil versus iloprost: dose effects. (A) Inhalation of 7.5 µg iloprost (in 6 min) versus 7.5 µg treprostinil (6 min) (n = 14, in randomized order). (B) Inhalation of 7.5 µg iloprost (6 min) versus 15 µg treprostinil (6 min) (n = 14, in randomized order). (C) Inhalation of 7.5 µg iloprost (6 min) versus 15 µg treprostinil (3 min) (n = 16, in randomized order). Data are shown as percent of baseline values (mean ± 95% confidence interval). Circles = iloprost; triangles = treprostinil.
