A reduction in CVO2 with all else remaining stable is consistent with
an increase in metabolic rate
hyperventilation
polycythemia
hypothermia and induced paralysis
CvO2 stands for Central venous oxygen saturation. This is oxygen present in mixed venous blood.
It depends on SvO2 (amount of oxygen bound to Hb) and hemoglobin concentration in blood.
CvO2 is always measured from pulmonary artery. Reduced CvO2 means reduced oxygen in venous blood; this will not lead to increase in metabolic rate. It can be hyperventilation. In hyperventilation, the body respires fastly; so, enough oxygen is not able to enter the lung.
So, your answer is hyperventilation.

Everything else remaining unchanged, an increase in the supply of a good will lead to: a fall in price and an increase in consumption of the good. (this is the correct answer) an increase in the cost of production of the good. an increase in the price of the good. a leftward shift of the supply curve. an upward movement along the supply curve (this one is wrong) I found the answer!
