Figure 1From: The concentration of oxygen, lactate and glucose in the central veins, right heart, and pulmonary artery: a study in patients with pulmonary hypertensionOxygen saturation and lactate concentration at the various sampling sites. Nine patients were included. Values are expressed as mean ± standard error. *P < 0.01, §P < 0.05 comparing right atrium (RA), right ventricle (RV) and pulmonary artery (PA) versus inferior vena cava (IVC). †P < 0.01, ¶P < 0.05 comparing RA, RV and PA versus superior vena cava (SVC).Back to article page
