Which of the following statements about delivery-dependent oxygen consumption are true?
A. Below the critical oxygen delivery (D(overdot)O 2crit), one would expect to see a decrease in the lactate-pyruvate ratio.
B. D(overdot)O 2crit may be increased in patients with sepsis.
C. A desirable goal in the treatment of shock is to achieve delivery-independent oxygen consumption.
D. The oxygen extraction ratio remains constant as long as oxygen delivery remains above D(overdot)O 2crit.
