The value of SVO2 monitoring is to determine
a. oxygen saturation at the capillary level.
b. an imbalance between oxygen supply and metabolic tissue demand.
c. the diffusion of gases at the alveolar capillary membrane.
d. the predicted cardiac output for acute pulmonary edema.
B
Three of these factors (CO, Hgb, and Sao2) contribute to the supply of oxygen to the tissues. Tissue metabolism (Vo2) determines oxygen consumption or the quantity of oxygen extracted at tissue level that creates the demand for oxygen.
