Abstract
Abstract Introduction The use of the pulmonary artery catheter has decreased overtime; central venous blood gases are generally used in place of mixed venous samples. We want to evaluate the accuracy of oxygen and carbon dioxide related parameters from a central versus a mixed venous sample, and whether this difference is influenced by mechanical ventilation. Materials and Methods We analyzed 78 healthy female piglets ventilated with different mechanical power. Results There was a significant difference in oxygen‐derived parameters between samples taken from the central venous and mixed venous blood (Sv¯O2 = 74.6%, ScvO2 = 83%, p
