Figure 4From: The protective effects of a phosphodiesterase 5 inhibitor, sildenafil, on postresuscitation cardiac dysfunction of cardiac arrest: metabolic evidence from microdialysisLeft ventricular function evaluation based on invasive hemodynamic variables and oxygen metabolism. (A) Heart rate (HR). (B) Cardiac output (CO). (C) Mean aortic pressure (MAP). (D) Coronary perfusion pressure (CPP). (E) Mean pulmonary arterial pressure (MPAP). (F) Oxygen delivery (DO2). (G) Oxygen consumption (VO2). (H) Lactate (Lac). The values are reported as mean ± SD. ROSC, restoration of spontaneous circulation; SA, saline. *P < 0.05 vs. sham, **P < 0.01 vs. sham, ΔP < 0.05 vs. saline (one-way repeated-measures analysis of variance).Back to article page
