Lungs Pulmonary Shunting, Please Explain?

How would blood flow obstruction during shunt cause pO2 and pCO2 to approach that of mixed venous blood? Should one consider contributions from healthy alveoli in this question or not?
Also, when V/Q approaches infinity how would pO2 and pCO2 approach that of inspired air?
