Champion L. Oxygen delivery, cardiac function and monitoring. In: Fuller J, Granton J, McConachie I, eds. Handbook of ICU Therapy. 3rd ed. Cambridge University Press; 2015: chapter 1. Oxygen delivery = cardiac output × arterial oxygen content; ×10 converts mL O2/dL to mL O2/L, so DO2 (mL/min) = CO (L/min) × CaO2 (mL/dL) × 10. Typical resting adult values: CO about 5 L/min, CaO2 about 200 mL/L, DO2 about 1 L/min (1000 mL/min). (2015)
