Figure 2. Cardiopulmonary variables.

Figure 2

Groups are low‐altitude (LALL) and high‐altitude (HALL) newborn llamas infused with NaCl 0.9% (Control) or l‐NAME, basally and during a superimposed episode of acute hypoxia. Cardiac output (CO) in LALL (open symbols) and HALL (filled symbols) infused with (A) NaCl and (C) l‐NAME and pulmonary vascular resistance (PVR) in LALL and HALL infused with (B) NaCl and (D) l‐NAME. Values are means + SEM. B, basal; B + I, basal + l‐NAME infusion; EH + I, early hypoxia + l‐NAME infusion; LH + I, late hypoxia + l‐NAME infusion; R, recovery. Significant differences P < 0.05 (ANOVA + Student–Newman–Keuls test): * vs. basal; ** vs. B, B+I, R; § vs. all in the same group; †LALL vs. HALL; #NaCl vs. l‐NAME.
