WebMVO2 = Mixed venous oxygen saturation “it serves as an index of the adequacy of the oxygen delivery system” dissociative shock = blood has decreased ability to carry oxygen to the tissues (example causes: CO poisoning, cyanide poisoning, anemia) Webarterial oxygen desaturation often occurs in cardiogenic shock as a result of a decrease in mixed venous oxygen saturation (SVO2) and intrapulmonary shunting. SVO2 decrease occurs as a result of increased tissue oxygen extraction because of the low CO. In addition as systemic perfusion falls, compensatory neurohumeral mechanisms are activated.
