What effect would upper airway obstruction have on ventilation-perfusion ratio, PAO2and PACO2? A) The V/Q ratio and PACO2will decrease and PAO2will increase. B) The V/Q ratio and PAO2will decrease and PACO2will increase. C) The V/Q ratio and PAO2will increase and PACO2will decrease. D) The V/Q ratio and PACO2will increase and PAO2will decrease.

Upper airway obstruction reduces ventilation, leading to a decreased V/Q ratio. This results in lower PAO2 and higher PACO2 due to impaired gas exchange.
