An increased cardiac output causes the:
1. C(a-v)O2 to decrease.
2. SvO2 to increase.
3. total O2 delivery to decrease.
4. O2ER to increase.
a. 1
b. 2, 3
c. 3, 4
d. 1, 2
D
As cardiac output increases, less oxygen is extracted from the blood. Because of this, the C(a-v)O2 decreases and SvO2 increases. Increased cardiac output would also increase total oxygen delivery and decrease the oxygen extraction ratio.
