VO₂ = 1.34*CO*Hb*(SaO₂-SvO₂)

English Name: Oxygen consumption, VO₂

Normal Range: 150～200 ml/(min*m²)

Oxygen is not stored in the body and is fully utilized upon intake. Therefore, measuring oxygen delivery (DO₂) and oxygen consumption (VO₂) helps understand the circulatory system's capacity to transport oxygen and the tissues' ability to uptake and utilize oxygen.

DO₂ and VO₂ are influenced by cardiac index (CI), hemoglobin (Hb), arterial/venous oxygen partial pressure (PaO₂/PvO₂), and oxygen saturation (SaO₂/SvO₂).
