Neco Model Questions Vol1 2017 Biology Question 29
Practice objective / multiple choice question 29 from the 2017 Neco Model Questions Vol1 Biology examination.
A mountaineer ascends to an altitude where the barometric pressure is 560 mm Hg. He breathes ambient air (FiO₂ = 0.21). His arterial PCO₂ is measured at 40 mm Hg and the respiratory quotient (R) is 0.8. Using the alveolar gas equation \( P_{A}O_{2}=F_{i}O_{2}(P_{B}-P_{H_{2}O})- \frac{P_{a}CO_{2}}{R} \) (where \( P_{B} \) is barometric pressure and \( P_{H_{2}O}=47 \) mm Hg), calculate the alveolar partial pressure of oxygen \( P_{A}O_{2} \). Round your answer to the nearest mm Hg.
