WebThe VO2 observed (oVO2) by a clinician (either measured or calculated) is the product of an observed DO2 and an observed EO2, such that oVO2 = oDO2 × oEO2. Similarly, the specific patient’s requirements (nVO2) may be formulated as the product of the needed DO2 and the needed EO2: nVO2 = nDO2 × nEO2.
