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 ?
Decreased ventilation-perfusion ratio-Decreased oxygenation due to decreased ventilation with respect to perfusion-PaO2 decreases and Pco2 increases.
