Physiologic rationale of Sv-O2 monitoring.
Mixed venous oxygen saturation is a global indicator of the balance between oxygen transport and oxygen demand. In critically ill patients, the delivery of adequate quantities of oxygen to meet the cellular oxygen demands is paramount. While parameters such as SaO2, PaO2, and CO reveal important information about oxygen transport, the SvO2 indicates the adequacy of supply in relation to tissue oxygen demands.
