Cardiac output and global oxygen delivery in rats at varying levels of anemia. (A) A strong inverse relationship (y = -0.07x + 24.9, r² = 0.83) is observed between cardiac output and arterial blood oxygen content. Decreasing arterial oxygen content and increasing severity of anemia results in a proportional increase in cardiac output. (B) A strong positive relationship (y = 0.01x + 0.86, r² = 0.82) is observed between global oxygen delivery and arterial oxygen content. Reduced arterial oxygen content results in decreased global oxygen delivery, especially under severe anemic conditions. Data from Tsui et al. 2014.⁴¹
