Graph given below demonstrates ventilation-perfusion ratio curve for the normal lung. If V/P ratio is decreased , what shall be the effect on pCO2 and pO2 ?

A
| O2 tension, | CO2 tension
B
O2 tension-No change , | CO2 tension
C
|O2 tension, |CO2 tension
D
| O2 tension, | CO2 tension
High-Yield Explanation
Decreased ventilation-perfusion ratio-Decreased oxygenation due to decreased ventilation with respect to perfusion-PaO2 decreases and Pco2 increases.
