What would the P_IO₂ equal at the summit of Mount Everest where the P_B is 253 mm Hg? A) 43 mm Hg B) 159 mm Hg C) 79 mm Hg D) 100 mm Hg

Question

Quizplus · Accepted Answer

The partial pressure of inspired oxygen (PIO2) can be calculated using the formula: PIO2 = (PB - PH2O) * FiO2. At the summit of Mount Everest, PB is 253 mm Hg, and PH2O (water vapor pressure) is typically 47 mm Hg at body temperature. FiO2 (fraction of inspired oxygen) is 0.21 (21% oxygen in air). So, PIO2 = (253 - 47) * 0.21 = 43.26 mm Hg, approximately 43 mm Hg.
