Description : 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 ... oxygen extraction ratio remains constant as long as oxygen delivery remains above D(overdot)O 2crit.
Last Answer : Answer: BC DISCUSSION: Oxygen consumption is said to be delivery dependent below a critical point, D(overdot)O 2crit, at which anaerobic metabolism supervenes. Above this point, oxygen ... the therapeutic benefit of trying to achieve supranormal oxygen delivery has not been firmly established
